[Android Head-Units] mimoat:
Hello guys, first I want to say thanks to everybody sharing their knowledge!

In my case I have a Ford Kuga (Escape) 2015 and a Junsun 6/128 GB MTK 825X and got hard times to setup everything correctly.

I thought maybe my notes are helpful for others.

Bad things first.

Whats annoying me:

For the keys in the middle I have sometimes no backlight (even in the evening). When rebooting (Via TorstenH's apk) or using Code 4 in Factory Code prompt, it works again; my guess is that in FastBoot / SleepMode the clock is may not correctly synced with CAN Bus (or Ford "SYNC" system).

May good to know:

Android Head Unit Fitting

There was always a gap between the Android Radio Unit Frames and the rest of the other parts of interrior, which annoyed me.

Luckily I read a comment on a youtube video of android radio installation on my car. The video was partly crap, but the comment gave me the correct hint:

With a dremel I had to cut some interrior parts, to make the frames kind of fit (not fun work, but ok).

Additional note: Even if put back the old radio unit, it will not be a problem because the original parts will also cover the cuts, so that was a good option for me.

Bluetooth

It seems like - if you set up selection of CAN configuration correctly - the Ford SYNC stuff now will be available again:

So e.g. if your device was connected before installation of Android Head Unit to Ford Sync, It will be connected again after installation. This caused a lot of unwanted issues for me.

So it is may better to delete SYNC from bluetooth from your phone.

External Mic

The shipped mic was crap. bought a Blaupunkt for about 15 €. (https://www.amazon.de/dp/B07CC9R8S4?psc=1&ref=ppx_yo2ov_dt_b_product_details)

Also had to desolder the microphone (my JUNSUN had no cables for microphone, so "new design" of the board). Even no problem for me desoldering the very first time in my life. Now internal mic will not interfere with external one. At least my wife says that she can understand me better.

GPS

My Android Head Unit was shipped with a small GPS Mouse. But then I noticed that my car already has a "FAKRA" cable (original), which seemed to be the GPS antenna (because the connector had small blue parts).

Bought a FAKRA to SMA Antenna Adapter and have about 6 sattelites more than with the GPS mouse.

USB Stick /Firmware Updates

On my macbook I used Disk Utility to format a 64 GB usb stick to FAT32. The firmware update did not work out due to not finding files (can't remember the exact error, sry).

I checked it aferwards on windows and noticed it was not FAT32 but exFAT - so macOS lied to me ;-)

Then I noticed that Windows did not allow me to format the stick to FAT32. I think it is because it's storage is >32 GB

So used an old 16GB stick and formatted it in Windows and added necessary files, then the Firmware Update was no problem, but took quite some time:

Imho plan about 25 minutes for firmware update. I took the risk and did it in the car, but decided to at least move the car to have less battery drain while doing the firmware upgrade not risking bricking the Unit by sudden death of battery.

Also I noticed that the update itself was tilted/rotated by 90 degree against clock, which first scared me.

After the bootlogo popped up the bootanimation took a loooooong time and got me nervous again, but after about 10 - 15 minutes my home screen popped up.

RADIO (WIP)

FM Radio is ok, but not as good as original radio. I learned that the original Ford Radio had a "Dual" Receiver, which the Android head unit has not.

Also my Ford Kuga has 2 antennas: One is already active / has power on it (currently connected to Android Head Unit) and the other antenna is passive.

Upcoming steps:

Install/Configure TorstenH's AppSwitcher App

before that I think I have use Some Logging App to find the correct KeyCodes, right?
