GPS 18 USB Deluxe Add-on GPS Reciever

Accurate unit. Have owned for over 2 years and highly recommend it to my friends and family. I currently own 3 different GPS units of various brands and this one tells me the most. Good clear voice. You can also attatch an external submini stereo jack to your head phone jack on you laptop and then connect the sound output to your cars speaker system. It also adjusts itself to the time your at meaning if its getting dark out side, it knows where your at and adjusts the screen colors and brightness accordingly. Has never made a mistake. It might take you a slightly longer direction to get where your going but it has never steered me wrong. My wife didnt trust it when we first got it until she made the wrong call several times and she got us lost and the GPS was right every time and had to correct our trip and direction. If you miss a turn it will auto-correct your mistake within seconds to the next available turn. For the price, this is a steal. Makes your laptop much more useful. I invested in a car mount for my laptop (Acer) and now it wont fall off the seat.

I bought the GPS18 to work with software I already had, aviation planning software for my tablet PC. The GPS18 sits on top of the dash in my airplane, plugged into the tablet PC, and shows my position directly on the aviation charts. For that, it's perfect. The GPS18 also comes with software for navigating in a car. I installed it just to try out, and it's very clunky as compared to alternatives (Streets & Trips, Delorme, etc.).

At first we could not use it. I called garmin and got the proper drivers then it worked like a charm

Works great around large areas and on major roads. Some of the streets that appear in rural areas are non existant, some places there were no roads when the map was showing a road there.

It does what it says it will do, very good directions loud and clear
