Finally pulled the trigger and got a cheapo (ish) 9" android (OEM- ish - look) head unit to try out on my e46, specifically to have CarPlay.
So far, it’s great! Easy to install, Android 10 and relatively responsive. It has CarPlay built in, so no dongle necessary.
The only issue I’m having is that when I plug in my phone for CarPlay, it seems to act as an antenna. I hear some static through the speakers briefly, and then a quiet, but high-pitched interference - type noise. Any other mode works fine, radio, bluetooth, etc, but when my phone is plugged in, there’s some odd interference.
Trying to figure out if I should swap units, or if it’s just going to be the same across all of them... I really like it, I just want it to not have the noise! I’ve tried moving cables around, isolating only having one thing plugged in, but nothing seems to change the interference. Maybe I should’ve gone for the Android 9 + dongle instead.
