Ok, quick update. I came downstairs last night to find my car with the headlights and reverse lights on! No idea why, but I pressed the lock button on the remote and they turned off. This morning, no suprise I had a flat battery. The syncmate turned up today, and after a good few hours charge the car now starts.
So if anyone with the thor engine has a sync problem give me a shout and i'll lend you mine.
