Glad to hear you got it sorted Trueblue, I have same setup and used the Migsel fjr mount which is again superb, thing doesnt wobble at all. I am very pleased with the Rider V2, its a real quality bit of kit.
out of interest, I recently bought a new 650 V Strom for local plodding about and got the suzuki offer of a Zumo 550 for Ł99 ( which I took of course ) ,
comparing the two, Garmin is again a quality bit of gear but the Tom Tom is better to use, garmin on screen maps not as good, voice promts way too quiet even on max, and although both have some good points the other doesnt, I'm glad I have the Tom Tom for the FJR. both traffic updates and speed camera warnings are MUCH better as well.
that Scarlo rider headset's a good bit of gear as well with volume increasing as noise goes up, i'm well chuffed, and glad I got the wife to buy it for me at christmas !!!
