I'm planning a trip to Norway in September and am thinking about getting sat nav for the bike. Problem is I don't know which to get. Rider 2 and Zumo 550 seem to be the main options but not sure which is going to be better. Rider 2 comes complete with basic bluetooth headset and is cheaper than the Zumo which, if you get what you pay for, suggests it's not as good as the Zumo. This concurs with some opinions I've received wich point to the Zumo being easier to use. Does anyone out there have any experience of one or the other (or both) that might help me make the decision? To be honest I probably won't use it much beyond longer trips like this so if it's a bit awkward to use it's not a problem as I won't be using it on a daily basis. Failing that, I'll just plan it on google maps and take a print out with me
