But... now we have the Jeep GPS RT 300. Really, how different can it be from any other GPS on the market? Did we really needed that? I know fans of the car will buy it, but does it have a market elsewhere? Would you buy a Jeep GPS device to attach it to your Kia Ceed or whatever?
Next, the Garmin Colorado comes with a handheld series for their GPS line: the 300, the 400.

It has some interesting features, starting with the wheel on top and the ability to show aerial photos (raster imagery) . More, the device has wireless capabilities and support for the display of detailed geocaching information.
More details here.
