The Go 910 is definitely the best GPS device out there today. I used it on a long sojourn on the East Coast over the Fourth of July weekend and it never missed.Before I left I loaded up a bunch of playlists onto the device with plenty of room to spare!! Before I left I was concerned about the mount drooping in the hot weather. I don't know if people have tried this, but you have to turn the dial on the mount such that it clicks in twice. There's a first click, then dial farther until the padlock symbol meets the dot. Even in the 90-degree weather the dock didn't move.Voices had some trouble with street names, but still, with the text-to-speech it was nice to have something more than the generic "turn right here."Love the big screen, better than Nuvi 360 AND the Streetpilot c550, my next turn was always visible well in advance. Phone conversations were clear and map accuracy was fine.A GREAT product!
