Check out the DeLorme Earthmate GPS package. We purchased one from CompUSA, loaded up the RV and it works like a charm.
Turn your laptop PC into a powerful GPS navigator with this high-quality GPS, featuring high-sensitivity chip technologies. Includes Street Atlas USA 2005 software with voice commands and other functionality designed specifically for in-vehicle GPS tracking.
Now you'll never get lost again with this affordable way to experience GPS without requiring a built-in GPS system. The low-power GPS can be powered for hours by your laptop PC's USB port. Ideal for everyone who travels frequently, this device will pay itself back quickly in gas savings alone, not to mention all the time typically lost driving in circles around unknown places across the U.S. and Canada.
