MMI unit in to my E92 335i. Feels like 2016 in here now...
iDrive maps... no DAB etc but still a Bluetooth connection.
I ended up removing this unit twice before leaving it be the third time
I should say I had repeated crashes when trying to play anything besides podcasts with the MMI unit. Carplay would crash when pressing play on Music, Spotify and Radio apps, skipping tracks etc was fine.
Turns out there are some quite widespread issues among Carplay users which seem to stem from when an iPhone is restored from an iCloud backup, originating around IOS 14. Both my XR and 13 wouldn't work but my O/H's 12 would (same IOS). Ended up needing to 'Reset All Settings' (but not a total erase).
Thinking about the reverse camera add in for £35 but I'm not in a rush.
