Hi!
Yesterday I got new firmware for my Andream Wireless CarPlay MMI CIC
LINK to site
You can find the files
here
Reason that I asked for the latest version was that I hade problem getting Android Auto to display in 720p view on 8.8" screen in my BMW Z4 E89 2011 (wireless)
At first it didn't help until I reset my system settings on my Samsung S10
If you still have problems try to set 720p in developers mode on Android Auto
I have tested with Iphone 5S wireless without any problems.
In my car you need to use AUX cable to get sound from Andream.
Best place for the microphone is beside center speaker under the grill
My box is placed behind and under the original stereo unit.
Wi-Fi antenna is placed above stereo unit on plastic ledge.
