DeLorme's new Earthmate GPS receiver and Bluetooth PowerPack cradle retain the bright yellow-and-black color scheme that marked previous Earthmate models. The GPS receiver itself weighs only 2 ounces and can connect to non-Bluetooth systems via a USB cable (included), but for wireless connectivity, you must insert it into the bundled PowerPack. As a result, the whole configuration, which costs $319.95 (or $129.95 for the receiver alone), weighs in at 5.5 ounces and measures 3.75 by 2.4 by 2.0 inches--easily the largest device in this roundup.

The Earthmate comes packaged with DeLorme's Street Atlas USA 2004 software for desktops or laptops. You'll need to shell out an extra $40 for the handheld version, which supports both Pocket PC and Palm platforms. This program lets you select which grids you want to sync to your PDA. Street Atlas supports voice-guided driving directions; contains more than 4 million points of interest (POI), such as ATMs, restaurants, gas stations, and major attractions; and allows route creation on the fly. Street-level maps for the New York tristate region requires 28MB of memory. The user interface provides clearly marked menu tabs for creating routes, exporting maps, and creating point-to-point directions. The Bluetooth kit also includes AC and DC (cigarette lighter) power chargers, a rechargeable lithium-ion battery, a desktop version of Street Atlas USA 2004, and a nine-pin serial cable for those who don't have a USB laptop.

Our in-vehicle testing was also positive; the Earthmate's signal retention and tracking accuracy were spot on. The battery, rated for up to 7 hours of life in the power pack, gave us just that, with a few minutes to spare.
