I've had both the Quest 1 and the Quest 2. Trust me when I say that the Quest 1 is the better of the two. Granted it has less memory but it's easy to load the maps along your route and it's very reliable. The Quest 2 (and I've had two of the poxy things) lost satellite lock at the first sign of a tree and had a painfully slow screen redraw rate so that I ended up riding off the screen. Not such a drama on the motorway but in town a total pain.
