I went for the Garmin Zumo 550.

I've noticed that there isn't alot of space on the left hand side of the bars and there is a wire covering what space there is. I'm just hoping that the clamp is small in width.

I've got a TomTom One for my cage. It'll be no good on the bike and to be honest it's so slow since I've added all the speed cameras and not waterproof. It's ok for a starter but lacks processing power. The other problem I have with my TomTom is I have a heat shield windscreen which make reception a bit slow. This Garmin I'm getting will be purely for the bike. I'm just hoping it's the dogs danglies as it aint cheep but hopefully a worthwhile investment.

Cheers for the pic Guv.
