thanks... the dealer at a local install shop stated the following
1. it has built in bluetooth
2. it has upgraded 80Gb harddrive
3. It has improved voice recognition
hey don't kill the messenger, that's why I came here to get the facts... I know I'm a noob, but I've been browsing for quite some time now, and have owned and installed numerous Pioneer nav units over the years, anyway, thanks for the response
