Stereo system gone unexplainably faulty.....

[Danny]

so its possible i may just need to re-seat the radio unit? i havent been able to get down to my car cos i've been a bit busy tho so its not yet sorted

how could it have disconnected itself though? it's been fine all along then suddenly i get in it and its not working

Ok, think I need to explain this a little better!

I am NOT sudgesting that a fuse is blown.

What I am saying is that the screen and radio appear to only talk codes when first powered up so if for some reason the code in non-volatile has become corrupt, it needs the power cycling to get them to re-communicate.

The no function operation is due to the radio and display having not verified they both have the same code.

thank you for all your replies, I went to the garage on friday to collect my car so i could begin faffing with the radio, they'd left the ignition in the ON position and flattened the battery!!

upon charging enough for me to start it, i turn the key and lo and behold the screen comes on fine, and all functions resumed as per correctly!!

had the battery not been flattened i think removing then replacing the main unit would have also been sufficient to cure the problem!!

so did you not have to type in your code?
because I have the exact same problem
radio works can change station using left and right buttons plus can change volume but thats it, no other buttons are working.

Could you tell me which fuse it is please? (sorry, i really am rubbish)

the car is at the garage (another story) but i can nip down and faff with it anyway

F12!

YES ITS WORKING AGAIN, just take out the fuse and put it back in.

honestly I dont know how you knew that but thank you.

i couldnt even change the station with the left/right buttons!

because it's paired properly with its computer, a code wasnt necessary, which is good because i dont seem to have the car pass!

good to know yours is working again too
