Does anyone else in here have GPS navigational systems in their cars? (Mods if this is in the wrong thread, please feel free to move and accept my apologies) I have a TomTom GO 910. It has work great for me. I've used it on back roads in western PA, and it has successfully gotten me through the web of ridiculousness that is washington DC. It also has some pretty cool options, with the bluetooth connection. My entire phonebook is stored on it now, and I can make calls directly from the screen. Any other tomtom fans out there?
