Hi John
One of the things my car started doing was giving one beep as I went past a certain speed around the legal limit. I could not find anything in the manual that might have been set to tell me I had reached a certain speed. Really irritating going down the motorway as the speed varied around that point! It started after a minor service, I took it back and after a 15 minute wait the OPC stopped it. No idea what might have caused it. On another occasion I tried to update the sat nav maps with a DVD off the internet - it then stopped working even with the old DVD. Again similarly I took it in to the OPC and 15 mins. later it was done FOC - when I offered to pay all they said was 'it's part of the service' - they seem to look after their customers (Lovets, Swindon). Again no idea what the problem was. In my experience, these odd things just seem to need a reset, hope yours is as easy.
