Yugster offers the refurbished Magellan RoadMate 5" GPS Navigation System with DashCam Recorder for $59.97 with free shipping. That's $120 off and the best price we could find. It features 5" capacitive touchscreen, WiFi, HD dashcam recording and lifetimes map updates.
Note: A 90-day Magellan warranty applies.
There's a less expensive way, and then there's the way that works for you. The two may not be the same.
