calnorth I've turned off after it happened yesterday 'auto turn up volume with vehicle speed' so will see if that fixes it.

Not expecting it to really.
Importantly the ON/OFF switch is a press button (contactor thing) which means in your case that its being skirted. Thats one method of powering the headunit and I would expect to be the master control. I see a number of power inputs or triggers to the headunit from the ignition switch + battery...about 4. One of them I think is ACC which provides power when the engine is OFF. There are many others including IPDM and ECU....which complicate things and possibly not relevant?

I only have a diagnostic block schematic for the AV system...so headunit internals are anybody's guess.

If the Power button is OFF and the unit suddenly self switches ON I'd have to say the headunit is faulty. For me it would be a case of seeing what was physically wrong with that switch. Its a bit fishy...power and volume on the same physical control.
