Update: this is now $249. Amazon has the Magellan Roadmate 360 GPS Receiver with Windshield Mount for only $199.99. Not sure about the price? Well, Crutchfield sells this for $450 and Amazon sells a refurbished model for $260! This comes pre-loaded with US & Canada maps, has a touchscreen interface and voice-prompted directions. Shipping is free. There is no sales tax (except KS, ND, WA).
