I *love* my new Nuvi 660, it's by far the best NAV I've had (on on my 3rd), and it tops all the reviews I've read too. But I have a problem trying to organize my MP3 library. (Or I will as soon as the 8GB SD card arrives) The MP3 player has a very limited BROWSE function, I can't see how to browse hierachically, e.g. Genre -> Artist -> Album -> Track, and I can't find a SEARCH functon either. With over 2000 tracks in my library it's going to be a nightmare trying to find stuff. I know many fellow Prius drivers have a nuvi 660, so I'm guessing others have come accross the same limitation. Perhaps there's a 3rd-party MP3 player one can install on the nuvi, or maybe there's an upgrade from Garmin (didn't see one)? Anyone ?? oops! miss-spelled "Garmin" in the tread title
