When it comes to portable GPS navigation devices, there are a few names that immediately come to mind. You’ve got your Garmins, Magellans, and TomToms of the world and then you’ve got companies that usually specialize in other items.

Motorola is a name that you probably associate with cell phones, but the electronics giant does GPS as well, as evidenced by the new MOTONAV TN20 and TN30, both of which are being sold exclusively through RadioShack. The TN20 has a 3.5-inch touchscreen, whereas the TN30 boasts a 4.3-inch widescreen. The maps come from NAVTEQ and you’ve got more than one million searchable points of interest at your fingertips.

Look for the MOTONAV TN20 and TN30 for $199 and $299, respectively.
