Manufacturer description
The Earthmate GPS PN-20 is a unique all-in-one GPS and mapping solution. Unlike other handheld GPS manufacturer's devices, no additional mapping software purchase or subscription is required. DeLorme Topo USA 6.0 DVD software is included with the device, with beautifully detailed topographic and road maps of the entire U.S., available aerial imagery, and a broad range of GPS capabilities. Based on features, capabilities, and ''under the hood'' power, the Earthmate GPS PN-20 is fully-positioned to compete at the high end of the handheld GPS market. Its high resolution (220 x 176 pixel) transflective color screen delivers exceptional visibility under a wide variety of conditions, including direct glaring sunlight. The 12-channel, NMEA-compliant receiver includes STMicroelectronics chip technology with SiGE frontend noise reduction, plus DeLorme firmware for fast acquisition times and outstanding signal retention. The device is WAAS-enabled for accuracy within meters. With its proprietary Kalman filter, the Earthmate GPS PN-20 also addresses the complex problem of reflected GPS signals, which could otherwise greatly decrease positional accuracy.User opinions

Great features, but poor performance.
Pros: Feature laden with terrific mapping and rather intuitive to operate. DeLorme maps are the best available. When it works, this unit rocks!!!
Cons: Motherboard failing after 2 years of limited use and there is no recourse. The company won't do anything at all. I can use it until it fails totally (scary scenario) or buy another one....so much for standing behind your product!
After expressing no confidence in their products that would not allow me to purchase another, they offered nothing. At the very least they should offer a trade-up deal to previous customers.....happy or not. They really don't care about their customers!

Just doesn't work very well
Pros: Excellent Maps (both on the unit, and the PC based TOPO USA map product that is bundled with it -- I would give that 4.5 stars) Ability to view aerial or satellite images over the map.
Cons: Extremely slow calculating routes. Will fail to calculate routes on complicated road routes. My cell phone can determine its position faster than this unit. Main use is for trails, but it often loses its position in deep woods.
