The Intellinav 3 is a small, boxy unit with a 3.5-inch touchscreen and external controls for volume, power, and Standby mode. It comes with a 2GB SD Card, a clunky window mount, an outlet power cord, and a cigarette lighter power cord. While it can store MP3s and JPEG photos, you’ll have to remove the SD Card if you want to put files on it, since the USB port is used only for charging the unit

Navigating with the Intellinav 3 was easy, but not a pleasure. The device offers Navteq maps, but they looked crude, lacking the visual polish we’ve seen from other manufacturers. The input menus are well laid out, and we liked the shortcuts menu, which lets you quickly get directions to your house or other frequent destinations, such as ATMs, gas stations, or parking lots. While the Intellinav can pronounce street names, there’s only one voice to choose from (but a handful of language options).

Setting a destination is easy, as is creating a multi-stop itinerary. Turn-by-turn directions were occasionally difficult, since the unit can’t pinpoint your car’s location close enough. We missed a right turn when the Intellinav told us to turn 500 feet up, yet the intersection was only 50 feet in front of us. Fortunately, rerouting is fairly quick.More here
