LG LN790

This feature-rich navigator offers sophisticated abilities such as text-to-speech conversion, a traffic receiver, and a Bluetooth phone interface, all in a box with a big 4.3-inch screen. Still, the LN790's price ($650) is way too high for a personal navigator these days, no matter how capable it may be.

The menu structure and the user interface on the LN740 and LN790 are identical except for some additional features on the latter. For both, the underlying navigation software comes from Destinator Technologies, a GPS software company that markets its products for PDAs, smartphones, and OEM partners. In fact, software from Destinator Technologies also powers the recently reviewed Pharos Drive GPS 250 ($299.99 list). While you'll notice many similarities shared by the user interface of the Pharos and the LN790, there are differences. That's because each manufacturer can tweak the UI and software to differentiate its products from competitors' devices.
