This is a new unit, not a refurb, and that $50 price tag is out-the-door: no rebates; Buy.com picks up the shipping.
As you might expect, this is a strictly no-frills navigation system, offering a 3.5-inch touchscreen, a suction-cup windshield mount, and an impressive 4 million points of interest.
That's fine: Not everybody needs frills. But there are red flags all over this GPS, starting with the fact that MyGuide is a European company, and there's no indication that the 2150 comes with U.S./North American maps.
Meanwhile, the MyGuide site appears to be down, so I can't find any information regarding specs, warranty, map updates, etc. Plus, I've searched high and low and can't find any reviews of this model.
Thus, if you'll pardon the navigation pun, your course is clear: skip this GPS. Sometimes a deal is just plain too good to be true. If you need a nav system for 50 bucks, consider Buy.com's other option: the Magellan RoadMate 1200 for $49.99 (after a $20 mail-in rebate). Yep, it's a refurb with a 90-day warranty, but I'd choose that over the MyGuide any day of the week. Here endeth the lesson.
