I have a Nuvi 660 and a Vista from garmin. Although you can connect the Nuvi to your computer and update from the Automated Garmin Update software, this only provides updates to your software and operating system. I assumed when I got the device and started "updating" that it would update the maps also. Then I saw yearly Map Updates for sale and wondered. So Garmin puts out an updated Map each year that costs about $69.00. If you just use the online updater, you can stay current with the various aspects of your devices' working software (i.e. traffic warnings, voices [German update, Romanian etc] and new colors or types of vehicles [motrocycles, monster trucks]). That does not update your maps. For that you need to purchase a map update CD and download the updated map to your device.
I have the 2008 and was in TV in February and it worked well. I did not use it to navigate the various streets as I was trying to do that on my own. It did get me there from Orlando without any problems.
