Jeep should stick to scaling mountains and whatnot. To be totally frank, we had all but forgotten that a Jeep-branded navigator was even in the works, let alone closing in on release -- of course, maybe that's because we last heard of this thing in December of 2007. At any rate, the ruggedized RT-300 has finally found its way to the review bench, and unfortunately for those holding out for this critter, it didn't fare too well. At all. For starters, $249.99 is a lot of scratch for a lowly 320 x 240 resolution screen, and the fact that it's not even waterproof didn't help matters either. Worst of all, testers had issues with route calculation (read: its main function), with a certain Cincy-to-Jersey query causing a total freeze three times in a row (and even on a second unit). Bottom line? Steer clear of this one, hard though that may be for the Jeep faithful.
