VIN Unlocking a GMT800 Navigation Radio for Bench Testing

- This is a brief explanation of how to VIN unlock a GM TNR Radio to test functionality outside of a vehicle. This specific unit is from a 2005 Escalade, but many GM radios in this year range operate in a similar manner.
Can I ship you my radio to be unlocked before I install it into my 05 GMC YUKON DENALI
It's the exact same radio as in your video ?
I have a 2006 gmc sierra 2500hd with the oem rear dvd player and was wondering if when the dealer programs it to my truck if I can still play the players audio through the trucks speakers when I change the source to the player?
Wondering if using the vxdiag could work. Which wires on the radio are for the odb connector ?
I’d like to see how you connected everything, from the tech 2 to the radio, is that possible?
Just an FYI, I used this exact same process of choosing the nav radio and then clearing the VIN info to relearn a junkyard base model radio with buttons and tape player
What year radio? I attempted and it did not work
I’ve got a 2004 Tahoe and am trying to put a nav radio out of 2006 gmc Yukon Denali. Would you be able to relearn the vin? Dealer told me that the part number was not listed in the tech2
It should be able to. Where are you located?
@@andyb1185 I’m in the southeast. I’m going to try and reprogram my eeprom with my vin. I’ve seen people have success with this and it’s a much cheaper option
Can you do that with any Radio
Where did you get your tech 2 from?
I am in Armenia. Can you help me unlock that ?
How do you un locked the same head unit without a tech2 ? Or is that not possible...
Need tech 2
Hey there, just wondering--would you unlock mine if I mailed it over to you? I have a GMC Envoy and I'm thinking of putting that same exact unit into mine. Please let me know. Thanks.
Where are you located?
Same question here if I pay for shipping to you and back could you unlock mine I have the same radio…
I have this radio in my 2006 Denali and have been really happy with it. No biggie, but the date and year no longer are correct. And from searching it seems to be a common problem. I thought this was updated through the GPS? Am I wrong?
They should be, yes. To be quite honest, I don't recall even seeing the date or year listed though
@@andyb1185 you press on the lower right under the time and a window pops up that shows the month and year. It always worked and as of 18 months ago it went back to 2000
@@jewllake I had no idea, I'll have to try that in my truck when it comes out of winter hibernation. I ran into a similar issue with a 2001 Toyota Avalon. The year stops around 2018, but reverting back to around 2002 was able to make the date and day of week display correctly
Looking into the same issue with a friends 05 Denali. The date is around July 20 2004… but the clock is accurate for now
Let me try again, Great video, I’m trying to do the same thing, While I wait for my tech2 to arrive, I built a small harness with the C1 radio connector on one side and an OBD port at the other, I connected 4 wires between them. +12v, 2 Grounds, and Class2 J1850 signal. I plugged a 15800001 in when I press/toggle the power button, the screen toggles between the TOD(time of day) and blank screen. I was hoping that it would display a Theftlock message or the normal power on message. Is there something that I need to do to wake it up like putting another class 2 module on the bus so that the radio wakes up. When I plug in my fancy OBD scanner, it does say the radio part number, but it won’t read the live data so I believe I have wiring correct since it appears it can talk to it.
..... or does your little network have a BCM in it as well and it drives the IGN0 ,Ign1, and Acc inputs to have the BCM think its in a vehicle/network and its then sends the appropriate message to the radio so that can turn itself on?????
What does output control do. Under the navigation radio menu
Primarily just allows you to test speakers
@@andyb1185 so if I wanted to increase the volume or change settings about the sound. Is there a way to do that?
Hi there,
Could someone please tell me what that little green plug on the radio itself is for?
That is the connector for the gps antenna
@@andyb1185 Thank you!

I have a Hummer H2 2009 SUV LUX ... "N" Truck product line I also have a GM TECH 2. My GM Tech 2 does not show a "Nav Radio" In The Menu. It only shows a "Radio'" and below shows "Digital Radio" I just bought a Brand new GM Replacement NAV Radio to replace the original one. It came thru Locked. There is no menu for "Relearn Vin" on the TECH 2. I can call up on the Tech 2 the Original Radio ID and other numbers but nothing where it says "Relearn Vin" Is my Tech 2 out of date? I have followed your video but it does not lead me to Relearn Vin. Thanks: Mark
