LG is still pretty fresh to the GPS market, but it's already kicking off a second round of devices with the LN790 Portable Navigator. The device features a 4.3-inch touchscreen, Bluetooth phone pairing, video and music playback and photo viewing, with an SD card slot to store the goodies. Oh, and that map stuff all those kids go for these days, with US, Canada and Puerto Rico pre-loaded, and live traffic info for 50 North American cities. You should be seeing this one hit shelves in September for around $699. More shots after the break.
