Head unit no AUX sound or joystick responding
Two months after replacing oem screen with inav, the head unit is not responding to console buttons or rotary joystick. No sound from AUX but, head unit DVD and radio works well. Got a quote for replacement with Pioneer unit but, it's expensive and can't wrap my head around having two screens and missing all BMW apps (TPMS, car info, etc). Buying a used knee from ebay is risking failure/mismatch and not guaranteed will work.
What would you do? 2013 x5m, thanks.
