Went to work and back yesturday all ok. Started car this morning radio and display all lit up as normal.But then relised no sound and not showing anything on the display. Drove to work work turned off engine and the radio and display wouldnt turn off. I had to remove fuse 12 to get it to turn off. Left it for a couple of hours and put the fuse back in and it all worked fine. Any ideas please i think its probably just a gremlin.
I had the same problem with my radio (CCR 2006) except that after putting the fuse back the radio and display gets lit up again and the radio doesn't function at all. I tried to switch it off manually by pressing the power knob but in vain. Since it happened I am forced to remove the fuse every time I leave the car for longer to prevent battery discharge.
I would remove the radio to do a hard reset - as Dave suggests, but don't have the required keys.
Any ideas on where to buy the removal tools or find a car audio service? Please help
