DIY: Improving Aux Input for Modern Saabs (Simon's Mod) - Trionic Seven
HTML-код
- Опубликовано: 1 май 2017
- Aux not working with your phone? Low Aux volume? This mod fixes compatibility issues with Aux input for Saab 9-5 and 9-3 head units and many phones. If your phone does not recognize that it's connected to the car's audio system you need this fix. Also, we raise the volume of Aux so that the radio isn't too loud.
The mod is Simon's Mod (named after the inventor), and his original guide in Swedish is here: forum.saabturboclub.com/showth...
This video also shows how to remove the stereo head unit and the full disassembly. This car has an integrated CD changer, but it also works in cars with a normal CD player.
Cars affected: Saab 9-5 2006-2010 and Saab 9-3 2007- without navigation.
My Samsung Galaxy S5 has this issue, and many Android phones do, too. It seems like iPhone is unaffected.

Swedish: Om du har problem med att Aux-ingången inte fungerar med din telefon, eller om ljudvolymen är för låg, kan du göra denna modifikation till stereons huvudenhet.

WATCH OUT! Removing resistors (those in series, not pull-up resistor in the front panel) and replacing them by a jumper or 0R resistors may result in damaging the DSP!! Because there is no input buffer realised on operational amplifiers or transistors.
The damage may be caused by malfunctioning aux cable or power surges.
Of course DSP cannot be bought easily and you will need to resolder the IC from the other radio. Soldering such DSP is not easy, it has a lot of outputs and also ground pad.
Thanks for sharing your knowledge!
@@TrionicSeven hi are you gonna make any more videos? Its been a while and i miss your videos😢
Thanks for sharing this fix. It has solved a problem that annoyed me for so long! It's not too difficult as long as you have a small tipped soldering iron and probably a magnifying glass. Be careful not to overheat the soldering iron else you risk damage to the PCB pads. The only improvement I would recommend to the process is that it's far easier to remove the 4 black plastic cosmetic screw covers in the dashboard by using a bit of very strong adhesive tape and simply pulling them out. If you try to prise them out it's almost impossible not to scratch them. Thanks again!
Thanks for sharing your experiences! :)
Just done this - took me 45 minutes and my AUX is finally loud!!! Thanks so much for posting this up - I dont really solder but found it not a bad job to do
Awesome! Good job :)
These deepdiving videos you make are really interesting to watch. I learn about saabs electronics that I never would on my own! Keep on going!
Dessa djupdykande videor som du gör är grymt intressanta att titta på. Mycket av Saabs elektronik hade jag aldrig förstått mig på annars! Tack för trevliga klipp!
Happy to help! I'm trying to put my own flair on the videos and keep them interesting. This is probably the most deep-diving specific Saab video I've made so far ;)
Nice to see that you like the mod :)
Thanks for finding it for us :)
Great Video. Just did my 9-3 08 Convertible, was buying leads and swapping phones until i watched this. No more aux problem and yeah the sound is twice as loud, took about 2 hrs all together. Many Thanks
Awesome! Glad to hear the mod works :)
T7, love your video yet again! Thank you for making these!
I came across another solution to the problem of Android phones not working in Saabs for music coming out of the car speakers. I had read somewhere that if you hook up an aux cord that has a volume wheel on it that will fix the problem of Android phones not working for music coming out of the car speakers. I went to my local Radio Shack and found one for 7 usd that had a female end and a male end. I used that in conjunction with my normal aux cable, and voila, it worked. Having 2 cables hooked up to eachother was a bit much, but seeing as how I drive people around in my car for a living, it made it so the people in the back seat could play their music without leaning forward or leaving their phone up front. I'm not sure if the cord has to have a volume wheel or if volume buttons on an aux cord would work. Though I don't think it fixes the loud radio/quiet iPod problem you fixed in the second part of this video. I would like to have the cojones to fix that like you did.
Just wanted to share my tiny bit of knowledge on this subject. If it matters, I have an 08 Saab 9-5 Aero that already had an aux jack on the stereo.
Thanks! I did think briefly about soldering a resistor to a 3.5mm cable and using it as that might have reduced that 3.3v output from the head unit into making the phone understand what's happening. Didn't investigate it that much, though. Your solution seems to be something to that effect. Good work :)
Thank you Trionic Seven. I did both mods in my 2007 1.9tid Saab. The only difference is that my car has a single CD drive. It works beautifully. I used duct tape to remove plastic plugs and simply covered the resistors with layer of solder in second mod (without any wires). To be honest the most diffucult part was screwing the radio back to the dashboard without magnetic tip screw driver :)
Hahaha, you are right. Getting the screws back was a nightmare of fiddling! Who at GM thought it was a good idea to do it like *that*!? Glad you got it to work :)
Superb job! Very useful video! I have the same issue in my 2008 Saab 95, now I am looking forward to get it repaired as I am a smd soldering pro.
The best of luck for you. Thanks indeed.
Good luck!
for those interested: this mod is the same on the saab- radio that has only a cd player. not a changer. works great
Thanx very much for this mod . I made the second mod it was very good . I still has the cd-changer too.I will thank Simon too.
Glad it works :)
TACK Jonatan. The same with my LG G4 in my 9-3. Looks like a headunit doesn't see it. Now I know why. On the other hand my old HTC M7 plays well. Thank you so much. Will have to dig my old soldering gun from the cupboard.
I posted your video to Polish SAAB forum as a lot of us have been struggling with this annoying problem. Cheers
Hey Maciej! Yes, you are not alone with this problem, and we can all thank Simon for finding the cause and solving it! Let me know if you have any more questions :)
Very nice methodical approach!
Thanks Jonathan superb video just did both mods ..with much trepidation ..but wow it worked !! Night and day superb !!!
Thanks, robert!
Good video. I do this mod to my 9-3 its littlebit different but can be done with this "guide". Big thanks from Finland.
Glad the video helped :D
Thanks for the video, did mine today and I succeeded! Soldering was pretty hard though, but with a bit of luck everything went like it should :D
You made it! Congratulations :)
Your sun must be over three now. Hope you are well, a lot happend since your last video. Take care!
Ah.. great info... my trick was to cut a audio cable and put two 10uf capacitors in series with the audio lines to get rid of the voltage. But i will now do the mods as described here to get the volume fix... (was about to insert an op-amp module in the audioline but this is much better. :) ) thanks for the info.
9-5 2007 with single cd player.
Yeah, I considered doing something similar before discovering this mod :)
All I had to do to fix the problem was to use another cable.
There's different kinds of audio cables. I changed from a cable with 3 black rings on the connector to a cable with 2 black rings.
Problem solved for me.
Thanks
Very interesting mod, well done...always wondered why the AUX volume is soooo low. (I have a Saab 9-3 2008)...out of curiosity:
Why do you think the original engineers put voltage dividers in the circuit in the first place? There must be some technical rationale behind it.
Was it to avoid accidentally receiving a high voltage (>5V???) on the AUX input to protect the circuit?
Surely the engineers would have noticed the big difference in volume between the radio and an AUX device? ( Did they think "yep can't see how anyone would mind that!!")
With this mod of bypassing the 2 resistors - is there a risk of damage or overload to other components?
Anyone know what is the max voltage in for the AUX?
Has anyone used a headphones amp to increase the volume? Do these devices just increase the input voltage which will get divided anyway (if no mod done)?
I am building up to do this mod as a project (have noticed a few suggestions below on using thermal paste/grease to avoid soldering - anyone tried this?)
Thanks
If you know how to SMD solder you can buy 0 ohm resistor to replace with for the low volume mod inside. 0 ohm will act as a bridge like a direct wire, but looks better.
Exactly. I had no 0ohm resistors available so I went for the wire instead. Thanks!
Schysst video och ett enkelt jobb om man har de rätta verktygen. Du är lite blygsam med ditt lödande :o).
Hehe, tack :)
Excellent video! Today I applied both mods and it all seems to work! Most difficult for me was to remove the air vent above the head unit. What a pain, all these snap joints! At the head unit itself I struggled with removing the antenna cable. The desoldering I did with an SMD desoldering station (I now may sound experienced, but this was my very first SMD work). In the first mod I kind of launched the resistor, because the air flow was set way too high. This proved to be a good training for mod 2 :)
I am now looking for a way to nicely connect my BLE module to the AUX, without using the socket at the front panel. Any advice for this? Would the pins 1,2,9,10 at the second (or right seen from the rear) connector of the HU (12779269) be suitable?
Hey, glad you got it to work :)
Connecting BLE to anything else but the front port is very difficult, however I'm tangentially involved in a project called bluesaab xm that is doing exactly this! Google "bluesaab".
Thanks for the good advice! My MY10 Griffin is suffering the same lack of Aux volume. Does the fix help the audio quality, as when i listen to the radio the bass and diskant is more deeper and clearer than with the Auxiliary. Kind of sad cause i have the Prestige Harman/Kardon audio system!
No, this just removes the attenuating filter on the aux
Hi. Is it possible to change the cd player inside the radio for another or do you need to use tech 2 for this? Just curious if the components are the same on the motherboard and compatible with each others?
I currently have a radio from my 9-5 with single cd. And another one from saab 9-3 with 6cd changer.
I bought a little Bluetooth-thingy from Kjell & Co, with a 3.5mm cable. That one is connected to the stereo and the little Bluetooth-box is attached to the side. Very small and nice. It works perfect.. much easier fix. ;)
That's a great idea, thanks :)

Does this mod, especially the second part also work on the Denso unit (the one with the Sat Nav). I have a 2009 9-3 Cabrio. And just to be on the sure side - the reason behind the AUX input sounding alot "blander" and "washed" out is the same volume reducer mentioned in the part 2 of the fix? What I mean is that FM and CD sound crystal clear and nice and loud and pronounced but the AUX input lacks a certain amount of dynamic. I have tested by burning some MP3-s on a CD and playing the very same MP3 files from my phone through the AUX input. There is quite a noticeable difference in quality.
Thanks in Advance.
Nah, the Denso unit is completely different and won't look like this inside. Don't know why aux sounds terrible, perhaps ask in our forum? facebook.com/groups/733705113501723/
exact same with me ...drove me crazy
Yeah, so annoying.
Hey so I have a question please. I have a 07 9-5 aero with the navigation radio. I owned a 06 9-5 with the unit in the video, it's a much better system. My question is can I swap out the Navi radio with this one without issue. Many thanks!
Unfortunately I think the wiring is different, but don't quote me
I have the galaxy S8, I don't believe I've had this issue. At least haven't noticed. BUT!
Would this make volume louder even if I don't have the issue? Also, my SiriusXM volume is 30%ish more quiet than my radio. I've always chocked it up to Sirius sound quality but now you're making me wonder if it could be something like you're pointing out? Thanks
Thanks for the info
This looks to be the solution I have been looking for, but does this work on the 9-3 2011 model? thanks
Yes, i think so (if you don't have nav)
Hey thanks for all the cool vids but is there a way to do something like this with my 05 model?
Your 05 doesn't even have aux input, so this video doesn't apply. Check out the following: ruclips.net/video/30qahGvou3k/видео.html ruclips.net/video/7CROC_q8KDQ/видео.html
hey, i only have the volume problem, should i only fix the last part or both?
It doesn't hurt to do both if you ever get another phone that doesn't work.
I use an 8Gb MP3 player which lives in the ashtray when not in use. Saves doing all this and doesn't drain the battery of my phone which, in the UK, is an area of motoring law where using your phone gets you a fine and points.
Does this the mod fix for low volume work on the 2007 with Nav? I can't stand how low the volume is coming out of my phone through the Aux!
Nav is a completely different unit!
my 2003 saab 9-3 that came with aux strangely when i put my phone on aux it creates this weird static that i cant seem to remove and its on the old icm3 head unit
Weird. Unfortunately, I don't know much about that car, as the ng9-3 is a completely different car from my 9-5.
Is the phone in the charger at the same time? I would blame the charger then.
Yeahhhhhh love you. one of the resistors has a drop of tin on it, the other one came loos.
Couldn't resist :D
;)
We have the navi unit from 2007. There is no aux input on it. Is there a way to connect a aux/usb signal to that head unit?
9-5 or 9-3? I know that bluesaab works with the 9-5 with navi, that's another DIY solution.
Hey, that's awesome! :)
Överväger också att göra detta.. iallafall det andra med volymen.
Första problemet ligger nog i att du har Samsung ;) skämt åsido, men både sambon och jag har Iphone och där är det inga som helst problem :)
Dock en 9-3 -08 men ska ju vara samma stereo!
Bra video! :)
Jag tyckte det var väldigt värt att göra ingreppet eftersom volymen blev så mycket högre. Lycka till! :)
Do you have a picture of how you shorted out the resistors for the audio level?
Check the guide linked in the description. Swedish text but great pics
Got it! Malwarebytes wouldn't let me visit the site, had to use my phone and translate it.
Thought I was the only one with this problem :D I don't dare to try this myself though
I thought this, too :) We are not alone!
nice! I'll give it a go.
Good luck :)
ska man alltså löda en metalltråd emellan de två motstånden när man vill att radion ska ha samma volym på radio-läget som på aux-läget?
Nej, du ska kortsluta de två motstånden var för sig. OBS: Det blir inte samma volym, men aux-volymen blir mycket högre.
@@TrionicSeven okej så man löser bara "rakt över" motståndet? Har lite svårt att hänga med på engelskan men bra film 👍😃
how did you short circuit the resistors? i noticed in the video you didnt really show how to do it. i have 0ohm resistors. would it be easier to replace the two resistors with two 0ohm resistors? my cd changer doesnt work either. is there a DIY for fixing the cd changer? i have a 9-3 07
Hey. The videos I shot where I showed the closeups where just useless due to the close focus distance of my camera. I used bare wire that I soldered "over" the resistors, shorting them out. You can def. use 0ohm resistors, too, but you must get the right physical dimension.
Do you know how to fix the cd changer?
What do you mean by fixing it? :)
i can load a a disk. it won't take the disk
so i took the head unit apart. tomorrow i will do the resistor replacement along with the removal of the aux resistor. i work at a place where we manufacture pcb
That is a lot of hassle rather than switching from a 3 way to a 2 way audio cable (about £3 on ebay). Still, good to see someone willing to get their hands dirty!
A bit late to the party, but something you can do if you don't want to solder is to use something we do when overclocking graphics cards.
We use a thermal grease that also conducts electricity, and just "paint" it on the resistor. It still has some resistance but way less than the resistor.
The benefit of this is that you can just wipe the thermal compound away if you want to.
I am unsure how long this will last, but I recon it will last for quite some time.
A little guide how you do it for PCs, but the application is the same.

Great idea, thanks for sharing!
hej
jag gjorde första lösningen på min saab 9-5a -06 biopower.
men nackdelen blev efteråt så verkar den inte vilja spela någon cd-skiva genom växlaren, men annars så funkade det riktigt bra.
Intressant, har faktiskt inte testat CD-växlaren efteråt. Borde inte påverka. Satte du tillbaka växlaren korrekt?
Trionic Seven jodå , jag tog inte loss växlaren utan ja tog bara bort fronten å tog bort resistorn så att auxen inte skulle kopplas ifrån.
men riktigt bra videor du gör iaf 👍👍
Ah, ja det förstås. Vet du, jag ska testa någon gång hur min cd-växlare funkar. Men måste hitta en cd-skiva först ;)
Tack för kommentaren :D
Trionic Seven haha precis, mer vanligt att man spelar via aux eller bluetooth.
för det var så konstigt när jag kopplade tillbaka enheten så började cd-växlaren "tugga" å sen när ja skulle spela via cd så står det bara att det är ingen cd laddad 😊
Säker på att du har CD i? Växlaren tuggar eftersom den letar genom förrådet för att se om något är laddat. Testa att mata ut/mata in igen.
No entiendo el inglés soy español quisiera saber cómo acero funcionar el mio
What is the music on your phone
I think it's Granite from the RUclips audio library. Just some generic royalty-free music
thank you
Don't forget that many Android phones have a headphone volume limiter which can be disabled (after ignoring a warning message) in their audio settings. I think that many iPhones are similar. (Example : www.samsung.com/us/support/troubleshooting/TSG01001429/)
While certainly intrepid, the simple fix is a Volume Control Headphone Extension Cord. I bought a few of them at Radio Shack for $49-cents on closeout. But similar types are all over eBay. The ever-sleazy Sears website has it for over $25.00. Sears has become a joke.
The volume control extension cord has a female for the 3.5mm AUX plug to fit into, and it's own male plug that fits into the SAAB's AUX input. Easy, quick, and give full volume.
I had this issue with my Samsung Galaxy Note 3. Since I switched to an iPhone, the volume control extension cord isn't needed.
Here is a link to the Koss VC20. Basically the same as the Radio Shack cord, but much longer. A shame really:
www.koss.com/accessories/cables/vc20
The Radio Shack cord is about 6 inches, and makes for a seamless, stealthy install.
Good tip, thanks! :)
Man, my saab 9-3 decided that it wanted to delete my aux source in my head unit and now I need to find a tech 2.
Which model year?
Trionic Seven it's a 2003 9-3
Strange! However, I don't know anything about the ng9-3, perhaps ask in one of the forums? Sounds strange that it should just forget it.
Omg this is ls soo much work for somthing that is $5 on ebay. And you can get rid of that anoying cable also..
What $5 device on ebay fixes this problem?
Lol mp3 disc, is it still 2001? AUX->Bluetooth adapter från kina brukar kosta ca 50kr. Funkar skitbra, har 3st och mycket nöjd jätte bra ljud, slipper aux kabel.
I've also thought of a Bluetooth adapter, but I actually have even more grand plans (Bluesaab!) In the meantime, however, the cable dance thingy was too annoying so I did the fix while developing the other solution.
I bought a bluetooth adapter. It suffers the same issue as your phone has.
just use a MP3 disc, the sound that comes out of the aux is terrible
mp3 disc? wtf?
Trionic Seven hi mine can play MP3 discs
A disc isn't even remotely comparable to Aux input. I use the phone to stream podcasts, hear navigation directions, audiobooks, music etc. Burning it to disc is like going back 20 years.
Trionic Seven I only meant for.music that's all, but anyways congrats on your channel, I really enjoy watching your videos
Each to his own :)
Smart to not show your soldering skills 🤣
Pro tip: Don't drive a Saab.
