I still mostly use my old Garmin but as an Android phone user I'm intrigued by Google's plan to modify their Android app to allow you to download maps of the surrounding area to your phone. Just enough of the surrounding area to avoid problems with cell coverage but not so much that it hogs space. Another option if you're an iPerson is Garmin's Navigon ($60) for the iPhone which supposedly stores maps on the phone.
One thing that appears to be missing from the Garmin's 2595 is full Bluetooth address book integration but that's not confirmed. It's available in some models but the reviews of the functionality are mixed and there appears to be some confusion about which models work with the phone's address book. That's something that I hope to see improved in next year's models. -- "Government is the great fiction, through which everybody endeavors to live at the expense of everybody else." --FREDERIC BASTIAT--
That was long overdue with Google and Google nav, I already have a gps unit but navigon stopped US operations for PND's so the maps are pretty much outdated.. last time I used it I was on a new road in the downtown area of N.C. and it shows me driving on a field.
I never cared much for the built in bluetooth on the nav systems because like you said they don't really show the phone book and unless I know that persons number in my head I most likely will just let it go to voice mail.
And the fact (may not be true now) but it's hard to hear the caller or the caller has a hard time hearing me well. -- It's NOT Ni-kon It's NE-KON!
The problem with downloading surrounding areas to the phone... 1) will you always know you won't have phone service in that area and 2) what a _huge_ pain! When I use my phone for navagation I'm in the vehicle driving. I'm not at home downloading maps so I will have them just in case my data connection is not good.
I still use my stand alone GPS unit all of ther time. I also have a few apps, such as iGo and Navagon installed on my phone. I get lost a lot.
