Ladies and gents, we have a new low! Buy.com has the Magellan RoadMate 2200T GPS for $59.99 shipped (after a $30 mail-in rebate). It's a refurbished unit, but it's also the least-expensive navigation system I've seen yet.
Needless to say, this model is a couple years old, so don't expect a lot of bells and whistles. It does offer text-to-speech, music and photo players, an optional traffic-monitoring kit, and a "smart detour" feature. Hmmm. Come to think of it, you get some bells and whistles, after all. It's even waterproof!
CNET awarded the RoadMate 2200T 3.5 stars out of 5, the major complaint being its sluggishness in switching between applications. I don't know about you, but I can live with that--seeing as I'd probably never use the other applications, anyway.
Because this is a refurb, the warranty lasts just 90 days. The rebate offer (PDF) expires February 4, but I suspect that these RoadMate 2200Ts will sell out well before that date. A full-feature navigation system for $60 is really tough to pass up.
