Hi,
I was also torn between the 2610, 2720 & Tom tom rider.
In the meatime I got a Tom tom rider from my other half for christmas.
So far...it's very easy to use & much easier to see with its bigger screen.
It did come with several different mounting brakets,
though none seemed to really fit on the Sprint,
(even though the tom tom brackets fitted ok on my other bikes), I ended up using a universal nokia handsfree bracket (as a base for the Tom Tom mount) mated on the LH bar bolts on the top yoke!
It only came with the UK Map loaded so I guess I'll end up forking out for the Europe map set on CD or SD card (if the SD has the same map detail).
Tho don't think they cover Eastern Europe (Bulgaria & Romania) yet !
Also waiting for the car mounting kit to be released soon, so I can use it on 4 wheels as well.
Neil.
