Review: LG LN740 Portable Navigation Device
September 2007 By Grant ClauserThe LN740 stands out from many of its competitors in that it’s incredibly small and thin. It’s less than an inch thick and less than a pound so you can easily pack it in a backpack, purse or even cargo pants pocket to carry around with you. There’s also no flip-out GPS antenna—the antenna is built-in and hidden. It has a built-in lithium ion battery so it’s as useful for walking around as it is in car. The map data is stored on 2 GBs internal memory but can be supplemented or updated with an SD card. Except for the volume buttons, the unit is all controlled with a touch screen.
My test involved a camping trip to Promised Land State Park in Canadensis Pennsylvania. After setting up the nav system with the windshield mount, it located several satellite signals in under a minute and was ready for me to input the destination. That proved to be a problem. No matter how I tried to search, the system wouldn’t give up Promised Land from it’s points-of-interest database. Since I didn’t have a street address for my campsite, I tried the next best thing—I entered the name of the nearest town knowing that when we got there I could easily take over. I also added another address because I needed to pick up someone along the way.
The unit calculated the route in about 30 seconds, then started pointing the way. The 4-inch map screen, while not as big most dash-installed screens, is big enough so street names, distance and other info is fairly easy to read. Zooming in for a better look is as easy as pressing the + or - buttons.
The unit includes a few convenience features I liked using. For one, you can view the turn by turn directions so you know what route you’re taking before heading out. The route summery option lets you see the whole trip in map form. It also can receive traffic and weather data via an FM receiver. This latter feature doesn’t require an additional subscription, but it’s also not always available.
