On the first tests I noticed that it took some minutes until a fix on the gps, particularly when I got out an interior parking. 3 / 4 minutes, sometimes more, is too much if you are in the middle of an unknown town and you don’t know where to turn to go to your destination.
The gps receiver was previously installed under the dash, then it was changed to the windscreen close to the rear mirror, with minor improvements. I decided then to buy a new gps receiver to see if the problem was there, but with no success.
When I decided last month to buy from AVIN USA a new HU with Android 8.1 I also bought their splitter cable to give a try to OEM GPS.
On the installation of this new unit I saw a “small” problem: there is a Fakra GPS connector on the back of my OEM radio but there is no cable attached to it, so I had to use the antenna that came with the Android HU.
After some search in this and other forums, I found that the connection to the gps antenna is on the trunk in the so called TCU - Telematics Control Unit.
So I bought a 5 m cable extension with Fakra Z-coding connectors and I mounted the splitter on the trunk and routed the extension to android HU.
The difference was immediate! The Gps Test app showed immediately a lot of satellites and a 3D Fix, and this last week the improvement is noticeable.
-------------------------------------
The second inconvenient i had with this unit was that the “original car” screen on the HU is either stretched or duplicated with a strange image.
I managed to solve that by “cheating” the car telling it had a 8.8 HU.
I used E-SYS to set on the HU_NBT the 3001 EXBOX > DISPLAY_VARIANTE = breites_display (wide display) instead of the previous “schmales display“ (narrow display). Then I changed the system parameters on Android to 8.8/10.25 screen and the original car screen is much better with no stretch at all and much nicer!

For those who might be interested not having to do the digging I did, I leave here this information and photos.
I hope it will be useful for someone.

Hi
Thanks for the information, I have exactly the same problem you described, how can I code the screen, I saw that you write something with E-Sys, I don’t really know what it is, thanks in advance
