Any help would be greatly appreciated. The original 6000CD fitted into my 2007 Mondeo suddenly decided to go permanently into one hour mode. Local Ford franchise thought the radio was defective, sent it away and came back with no fault detected. Then took it to an ICE specialist who checked the radio and no fault found. Re-installed and OK for a short while then reverted to one hour mode. I bought a new radio and fitted it, OK to start with then went into one hour mode. All fuses checked and OK.
I've had suggestions that it may be (1) the switched live feed or (2) the ECU.
Before spending more money on fruitless diagnostics, I wonder if anyone has experienced this or knows what the problem is likely to be?
Any help whatsoever would be appreciated.
