With its big 7-inch touch screen, the Garmin StreetPilot 7200 is very easy to use, and it has the latest in navigation unit functions, such as live traffic and media playback. Because it is a large unit, Garmin expects the 7200 to mainly be used in RVs and trucks, as cars may not have the space for it. Along with Garmin's already strong navigation and mapping features, the 7200 adds live traffic from XM or Clear Channel, giving it the capability to dynamically route around problems. Along with traffic, it can also receive XM radio stations and weather information. Its hard drive has room for MP3s, which can be loaded from an SD card and played through the integrated player. A built-in FM modulator lets music play through a car stereo. Going a little further, it has an input for a backup camera, although it's not wired to automatically turn on when the vehicle is put in reverse.
