Guess I am a little unclear on the differences between City Select and City Navigator. I already owned a Street Pilot 2610 with City Nav Ver 6. Last week I purchased a Vista C and got a second unlock key to use City Nav on the Vista also. I bought a copy of Topo US on eBay, so I have that capability on both units also. I guess the question becomes is City Select better, and if so, is it superior enough to justify buying a copy to replace my City Nav?
