I'm still thinking the radio as, for some, it has turned itself on during the night and drained the battery by the morning. It really doesn't matter either that you have the settings so that the radio unit turns off with the engine, if the fault is there it can still come on at any stage during the night and run the battery flat without you knowing. I've caught The Yellow Peril discoing away in my garage a few hours after he's been parked up :slayer: - No key in ignition...
