LG has entered the ultra-competitive GPS market this month with a splash, releasing the Portable Navigator LN730, LN735, and LN740. The LN740 is the most expensive of the three, sporting a larger 4-inch screen, more POIs, more storage, and real-time traffic. LG's new GPS line looked more promising than most, as the deep-pocketed company spent big bucks developing their own hardware & software rather than outsourcing both to the lowest bidders. Can LG compete with Garmin, Magellan, and TomTom in the already-crowded GPS market? Read on and find out.

Garmin's nuvi 880 can be controlled using speech recognition, includes MSN Direct for real-time traffic, gas prices, weather, and more, can navigate to geo-coded photos, supports multi-destination routing, and a whole lot more. Sporting a new, dual-speaker design, the nuvi 880 is a significant update to Garmin's award winning nuvi GPS product line, and, all things considered, is probably the best GPS money can buy right now.

With the possible exception of the 770 which includes European maps, the Garmin Nuvi 760 is the flagship GPS of the Garmin auto line. It has nearly all of the advanced features GPS connoisseurs look for, a widescreen display, Bluetooth hands free calling, live traffic reporting, and an FM transmitter. It also comes with a hefty price tag. If the success of the Nuvi 660 is any indication, the 760 is almost certain to be a winner.

TomTom's GO 920T costs about the same as the newer GO 930, but lacks the 930's IQ Routes and Advanced Lane Guidance. However, unlike the 930, the 920T includes an RDS-TMC traffic receiver, giving you everything you need to receive live traffic information right out of the box. The GO 920T has Enhanced Positioning Technology (for maintaining tracking when driving through tunnels and such), voice address input, real-time traffic data, Bluetooth, an FM transmitter, a remote control, and TomTom's innovative Map Share & Map Corrections program.
