The folks at Garmin are very responsive and friendly,try calling them and asking their opinion on the most suitable model for you.
I recently got a Garmin Nuvi 660 and got rid of an Alpine Blackbird. Have also had Magellan and various older Garmin Handhelds and StreetPilot's.
The newer units designed for point to point guidance are distinctly different thah the older models which were more utility focused.
The older ones really required route and trip planning from a computer to be uploaded to the GPS for use on the road.
They often had a baseline of maps but only primitive routing and direction capability.
The newer one have all that built-in but lack the basic GPS funcions the older ones had like connecting to a computer for real time mapping on the computer.
Aside from the GPS abilities they are like comparing Apples and Okra.
The Nuvi has been good but does some strange thhings ( they all do though) like suggesting it found another route that is better even though she just gave me the "bad" route.I can not understand why or what it is thinking there?
It always gets me where I need to go but often does so in a route I would never take nor will I take again.
If I know where I am going I often have to fight with the pushy GPS over who is right.
I hate that!
They also often do not understand that I have selected my own route until several miles of not following her "suggestions".
They are great and very annoying at the same time.
The Nuvi also has a Bluetooth speakerphone built-in and puts the caller-id info on the screen,this works well and I am addicted to it as it saves having to even touch or look at the cell phone while driving.
It also has an MP3 player which will play Audiobooks which I am also addicted to.
I use an Ipod through my stereo to do this though and I do not plan on changing but it is a nice feature if you do not have another way to do this.
I really get frustrated overall with the Nuvi but I also could not get by without it.
Come to think of it,just like some Non-Virtual Women I know?
