LG has brought its four satnavs to the US after first testing the market by launching them in Korea.

Although the units range from entry level to top-of-the-line, they all share a sunlight-readable LCD, a touchscreen display, turn-by-turn voice guidance, and pre-loaded maps of the US and Canada.

The first of the four is the LN790, the top-of-the-lint unit with a 4.3-inch LCD screen that features millions of points of interest, and incorporates an RDS-TMC antenna for live traffic updates. It also functions as a portable media player, with music, photo, and video playback, and bundled Bluetooth headsets, car and home chargers.

The next one on the list is the LN740, a 4-inch version with the technology to change automatically from day to night mode so that the display is always easy to read. It too features the RDS-TMC antenna, and photo and music playback.

The two at the bottom of the list are the LN735 and the LN730, which features 3.5-inch displays. All four units come with a suction-mount cradle, and will be on sale in the spring for between $350 to $800.
