Title: Pretty good, but you'll be dependend on some extra device
Review: I really liked this device when I got it. I have a dell laptop with a AC for the car and while its pretty combersome I really like having it. It has great reception and the voice prompt keeps me from looking at the screen all the time. All the functions are really helpful.The qualms that I have with this device is that you need to carry a laptop or pda (though i'm not sure if the gps would work - there aren't many pda's with usb). The whole setup ends up being pretty big and takes up the entire passenger seat. Additionally you need to boot up the compter everytime you want to use it...and if your speakers are quiet you'll need a usb headset or a line going into your car audio system to listen to the directions. I wish I had a smaller laptop and one with a better battery - if you have all that I would get this device, otherwise it may be a better idea to get the gps nav. computer with screen and everything attached to it (Garmin and whatnot).
