Customer Reviews

thoughts from a truck driver
I am a over-the-road truck driver and my blue-tooth gps unit started going out on me so I looked around for a replacement. Most of the review were positive and that had me really looking at this inexpensive gps. One person talked about loose connection I wonder if it might have been the user that had the loose connection as I have never had a problem with my laptop and gps bouncing around inside of the truck losing connection. I like the idea of a usb unit as I had already tried the blue-tooth versions and the batteries just do not last well for me as I drive between 5 to 11 hours a day. I have waited for several weeks after purchase and use to write this review as I wanted to give it a good try. I have drive all around the country during that time and I have been places where the road was next to a mountain cut-out on both sides of the road and still had gps lock the only places that I have lost gps signal was when I went through mountain tunnels but it picks back the signal on the other side within seconds. I would recommend this to anyone even if you are not a truck driver.

Fast locking in on Location, Very nice
This is the fastest lock GPS device I have used, and I have used about a dozen. One thing though-I was having trouble with it crashing my Vista laptop after a couple hours of use. I Solved this by going to Control Panel->Hardware and Sound->Device Manager->Under Ports->Select Properties of Prolific USB-to-Serial...->Port Settings->Change Flow Control to Hardware then->Select Advanced->Change both buffers to 1. And that totally solved the blue screen issue I was having.
Great product, best available USB GPS.

Excellent USB GPS Receiver!
Very simple to use and very reliable. I've used this device with SeaClear II navigation software for nautical and auto navigation and have yet to find a problem. Comes with a CD that will help you define a com port (meaning you'll assign one of your USB slots for use with the GPS). Also included is basic software to test and configure the device.

An excellent value!
