Isn't the screen too small? Does one really need that much technology to locate a Thai Restaurant in Manhattan?
While looking at new cars the subject of a navigation system came up...for 2 grand and I thought that I could do better with a portable. I tested in my Blackberry ...and figure it would be useful for both of us. Wanting to move into a smartphone with Voice Dial technology to get away from holding the phone while driving....expecting that in time the laws will require handfree phones I could kill two birds with one phone.
The GPS shows a broad map and as you approach the address you can zoom to the pinpoint location...visually. On the audio side you can just listen to the instructions and turn on command. We drive throughout 4 counties regularly so it comes in handy.
