Hi Paul One out of two aint bad!! Yes, i had completely forgotten about the centre push button knob! Its always been on the rotating setting which is not a bad thing at all UNTIL last week when trying to find an alternative route south to avoid the M5 Car Park which was J4a to J8, i couldnt get my mind oriented round the screen image and the map book. So, I'll try it this way on the way Oop North on Saturday. Would Factory Reset empty address book or would it mess up the radio stations?? Thanks for the help Ian BTW - I got off at J6, took A4440, then A38 to the M5O J1, which joined M5 south of Tewkesbury. Winner!!
