OK Guys, after some advice / technical know how / diagnosis etc
Recently I've been having intermittent problems with the main entertainment unit in my 2016 Superb 220hp. Sometimes the Sat nav wont start, i get a message saying Satellite Navigation database is unavailable. I would think this would just be updating etc but at the same time, the music that I have loaded on to the media card is not found , and what is even more strange is that when I remove the keys from the ignition, the radio doesnt always turn off. I have to hold down the volume button for 10 secs to get it hard shut down but even when it reboots the radio sometimes still wont turn off. Yet strangely I can start the car occasionally and everything works fine.
This has me flumoxed, all I can think of is disconnecting the battery and reconnecting but was wondering if there is a set way to do this without setting off alarms etc. I think Its the columbus unit with the physical buttons down each side of the screen, with Canton upgrade.
