TomTom Go510 and Garmin 2610 set up for European trip. Standard RAM mounts and homemade sun shields from cover of a dollar-store document folder, attached with velcro. Use one for navigation and other to examine entire route; one in mph, one Km/h; backup in case of failure, etc.
TomTom is hacked to add music playing capability (via BT) and trip logging featues. It's not waterproof but a sandwich bag fixes that if it rains hard enough. Both POI databases were crap in France. TomTom's was latest at the time and was worse than useless for basic things like finding hotels and ATMs
I have several 2610s and still keep hoping someone will find a way to create/convert/hack some updated non-NT maps. There are some things the 2610 does better than anything that has come since but their utility is slowly being compromised by more and more outdated maps. Shame Garmin opted to force obsolesence.
