Mine just started having issues last week, I havent' made any changes to it, etc. but here's what I've noticed:
Only 1/2 of the Map Screen loads in Map mode, in the Home mode, you only get the name of the road with no "map- This happens about 50% of the time.
All of my Map history/saved locations are gone.
It "lost" the connection to my WiFi- I reconnected it successfully and when I turned the vehicle off and back on, it had lost the WiFi into and was not connected, it will not stay connected.
The radio defaults to Sirius Channel 0 "SID" OR it will default to an FM channel (even when I've had it on a Sirius channel when I turned the vehicle off).
Voice Commands are working about 50% of the time.
Contacts aren't downloading about 50% of the time.
I have Version 3.4 Build 22251.
Having read people with similar issues, it seems it could possibly be a defective APIM module?
Note that it's going to the dealer for the Rear Axle Bolt and Rear Camera recall on 4/4, so I'm hoping they can fix this issue also.
Any suggestions would be appreciated as this is maddening
