Hey,
Thanks all. Some great info and tips on the Sat nav 'world'. I will be getting one and probably the Tom Tom Rider, as it sounds a good bet. Will be looking at 2nd hand too!   Brill to learn from other peoples experience, definitely can cut down on your own initial expensive mistakes.   I am going to Northern Spain and North Portugal on the bike for a month in July2011 (for those in the know I am not now going to Cambodia) A 'sat nav' as opposed to a 'sat nag' pillion (lol) will help me a lot me thinks, whilst there. In July 2010 I went there with a group of bikers and followed others! This year I am travelling alone and meeting friends over there as I have to miss Faro  (but luckily going to another rally there) Is the Tom Tom Biker ok for Spain and Portugal?
