Step aside Garmin and TomTom. While you two have been slugging it out in court, LG has prepped four GPS units hell-bent on muscling their way into the burgeoning North American navigation market. The LG LN790, LN740, LN735, and LN730 will all see their formal debut next week at CES. All four feature a 450cd/m2 bright touch-screen display, SiFR Star III chipset, turn-by-turn voice guidance, and pre-loaded maps of the US and Canada including millions of POIs. The top-o-the-line Bluetooth-enabled LN790 features a 4.3-inch LCD and an RDS-TMC (Radio Data System - Traffic Message Channel) antenna for updated traffic information along your route. And like most of theirGPS devices long available in Korea, LG delivers plenty of personal media playback options with support for music, photos, and videos. When you arrive at your destination you'll get an additional 4-hours or so of playback off the integrated battery. From there, the features begin to tail off with the LN740 dropping-in a 4-inch display while the LN735 and LN730 are both 3.5 inchers. All are expected to ship in Q2 2007 ranging in price from $800 to $350. The unit to the right is their latest model for Korea but should give you an idea of what to expect. We'll drop in a real pic once they're released.
