The TomTom GO 720 comes equipped with a 20-channel SiRFStarIII GPS receiver and maps of the United States and Canada and points of interest are preloaded on the device's 2GB internal hard drive. It securely held the unit in place, but we do wish there was an extra locking mechanism for the suction cup like some of the other systems we've seen, just to have that extra reinforcement and peace of mind. There's only one piece, and it easily slips into a slot on the back of the GO 720. The car mount is as simple as you can get. The TomTom GO 720 comes packaged with a vehicle mount (windshield and dash), a car charger, a desktop cradle, a CD-ROM with TomTom Home software, and reference material. As is, you have to go through several menu levels to do so, which doesn't make it easy or safe to adjust the audio on the fly. We missed having external volume controls. There is a jack to connect an external antenna on the back as well as the speaker. On the bottom of the unit, you'll find a 3.5mm headphone jack, a TomTom connector port, a reset hole, a mini USB/power connector, and a SD/MMC expansion slot, while there is a lone power button on top. It would be nice, however, if the keyboard was in QWERTY format instead of alphabetical order for easier text input. The virtual keyboard is spacious enough that most people won't have problems entering addresses. That said, we had a better experience after adjusting the screen brightness under the Preferences menu, where you can also change map colors and turn on night mode. For the most part, we had no problems reading the screen, but the map colors tend to wash out a bit in bright sunlight.

With a WQVGA resolution (480x272 pixels), the display shows off bright and sharp-looking color maps. The entire front side of the GO 720 is dominated by the 4.3-inch, antiglare touch screen.
