This morning after taking my car the day before to the dealership to get an airbag light sorted, my sat nav started behaving strangely. It was on map view and started flicking randomly through the screens without me touching it, I then tried to press a button and it did nothing, it locked up and then the screen went off, I've not since been able to get it back on.
Can anyone shed some light on this
Would disconecting the battery help at all? Obviously reconnecting it afterwards
