(Considering the LN790? Check out our review of the sibling LN735 which offers many of the same attributes.)
Finally at the top of the GPS lineup for LG is the LN790. There are two outstanding features about this GPS, there is a large 4.3 inch display, as well as the ability to play video files. The large display will make it easier to view the GPS if it needs to be located further away from you in the vehicle. It also will make watching videos on the device more tolerable.
You get preinstalled maps of the USA and Canada on this device just like the other LG models. Traffic alerts are possible through the included traffic receiver. With this model you also get Bluetooth capabilities which will provide hands-free calling.
Other advanced features include text-to-speech, and the SiRFstarIII chipset. Expect to pay about $800 for this device when it becomes available in the Spring.
