Conclusion: Chances are you didn't know that LG makes GPS devices, but if live traffic updates are important to you, the combination of a built-in TMC receiver, a big 4-inch screen, and text-to-speech conversion makes the LG LN740 a nice value.
Pros: Large 4-inch screen. Supports text-to-speech conversion in three languages. Built-in traffic receiver. Able to do multisegment routing. Estimated 6-hour battery life.
Cons: No audible turn indicator. POI menu awkward to maneuver. Map view doesn't display speed. Separate TMC antenna makes for a messy-looking dashboard.
