Summary:
(1) Test the GPS when install the GPS antenna;
(2) If put the antenna inside the car and without GPS signal,
put it outside to test if the car glass film block the GPS signal, if yes, install to A-pillar.
(3) When install 4G LTE antenna, keep a distance (more than 23CM) to GPS antenna.
(4) If have the GPS signal, but when you runs the navigation maps, it still no GPS signal,
that mean: the map might not compatible with the android screen. You can try to use Google maps.

Is the windshield blocking the GPS signal? Then why is it that even a very simple phone can find 10 times more signal than these android gadgets, even if the phone is under your seat or in the trunk!

Hello Paul. How does this device capture gsp signal if you install inside the car pillar? Doesn't the device need to be exposed? Doesn't the metal part of the pillar block the gps signal?
Please help explain to me

[@HifimaxOfficial]

It don’t need to exposed , my car installed to A pillar and it works perfectly in the past 6 years,

[@MaharionPendragon]

​@@HifimaxOfficial Thank you for responding! In this case, can I hide the antenna receiver under the (engine) hood of my car?
If yes, then I can just do it myself with some double-sided tape or just the magnet. If I cannot hide it under the hood of my car, then I have to install it into the pillar, and it will cost me money at the car workshop
