Having had the battery out, I went for a ride and realised I hadn't reset the clock and date. Having tried resetting both, many times, and checking the manual to see if I was missing something, it still will not change to the values entered. The manual doesn't say anything about the delete function which I have been using to delete the existing values, before entering the current date and time values.
I can change everything else in the display but the date and time refuse to be corrected.

Anyone else had this problem or have any handy hints? I really don't have time to go back to the dealer with this one and it's driving me nuts!
