Strange problem here, drove home last night, as normal, music on etc... parked up, went in, went to bed etc.
Woke up this morning, started the car (seemed to take a little longer than usual to start upon turning key) and found my radio was in safe mode?
I entered my radio code, which worked, radio back on etc, turned the car off, turned it back on and the radio is still working.
Any ideas what happened? And no the car has not been tampered with or touched overnight.
