In a car with GPS, DAB and RDS, I am amazed that I have to change the clock myself! 

Not that I have, I expect I will get around to it tomorrow.

What happens if you have it set to sync with GPS?

On the "Time" menu I just ticked the GPS choice & it automatically reset the time correctly.

Leaving it on that setting I hope will obviate the need to reset next Spring - am I being naive ?

When I came to do mine I found a tick box saying 'Summer (DST)' just under the time, I had no idea what is was for, it was showing ticked so I unticked it and the time automatically went back one hour. Guess I'll need to tick it again next summer.

Thanks lads - looks as though I was on the right track, but it defaults the less helpful way - will have a proper look tomorrow.

As "Has" said, I was using GPS sync, but had to untick the BST.  Satellites may need super accurate timekeeping, but they don't care about summer time.

Mine has no SATNAV. So had to unstick BST manually. Surprised it didn't sync with dab though as Juniperz said.
