One of the most basic Garmin GPS units is the 200W, but it is one that can still get you where you need to go. It uses a 4.3-inch wide-screen display and utilizes Garmin’s satellite mapping software. The unit itself sometimes needs updates to make sure it fixes bugs that can cause problems during use. You can also download improved maps, which Garmin offers as map updates. Both of these are downloaded and installed by Garmin’s required WebUpdater utility. Writer Bio
