Have used this NUVI 610 unit with local maps, have to admit that its very useful and an excellent effort. Comes with a build-in bluetooth, so you can connect your cell and dial/receive calls through the built-in mic/speaker. All the major landmarks (markets, fuel stations, atm, hospitals, etc.) are marked and would take you there on a single click think it had an mp3 player too (with a stereo jack, plug it into aux-in) and a detailed screen showing the current/avg speed, miles, etc.
