Sony 6CD DAB - Losing its presets

[JungleJim]

My Sony 6CD Dab (60 plate mondeo if it makes any difference) has decided it no longer wants to remember the preset radio channels.

Even if i re-program it loses them when I switch the radio off.

Any ideas on how to fix this?

It only happened this weekend - so far I know that it happens overnight, and also happened this morning when I tried reprogramming it and switching on/off (engine off).


Edited to add: Its happened after the battery in the keyless ignition key-fob was replaced. I don't know if that is the cause however, as the radio does switch on, just when it comes on its lost all its presets and doesn't find any stations easily.

Yeah, I need to find that out - manual doesn't mention anything about it. I'm hoping it will have solved itself when I get back to the car this afternoon!

Radio loses its presets whether or not engine is running, simply switching the unit off causes a loss of presets. Also, it seems to be taking some time to find stations.

Looks like a warranty claim in the offing then.

I pressed and held the on/off button for a period, the unit went completely black and then came back to life - like it had reset.

Weirdly all my old presets were back as they should be, so its not a complete reset but in any case its operating correctly again.
