Built-in navigation systems have improved in recent years, and they now offer more features for less money. (Some systems now cost as little as $500.) Compared with, factory-installed systems are well-integrated into your car’s operation and controls. They work seamlessly with the entertainment system, respond to voice commands, and can readily access your smartphone’s contact list. But keeping those maps up to date can be much more expensive and take more work than updating a portable unit or a smartphone.Unlike Google Maps on your phone, most built-in systems don’t continually update themselves over the air with new roads, lanes, interchanges, and businesses, or even traffic laws, such as speed limits and left-turn restrictions. Nor do they offer periodic one-click updates like leading navigation apps.Instead, updates must be purchased at a cost of $129 to $299, either through the automaker, dealership, or online.
Plus, there can be an extra charge for installation. For that much money, you could buy a very nice portable GPS unit with lifetime map and traffic updates. (Check out the, for example.).

The updated map software comes either on a DVD or an SD card, depending on what your car requires.

Having a professional handle the installation costs extra, of course.A Navteq spokesperson explained that maps are updated for each automaker every 12 to 18 months. At over $100 a pop, updating maps at that frequency is hard to justify for most drivers. But, if you routinely use a built-in navigator and/or count on it for periodic travel, best budget for at least one, if not two, map updates during your ownership period. During the holiday season, we've seen discounts offered on maps from several brands.If you’re road tripping for the holidays this year, you probably don’t want to risk heading out with a map that’s more than a few years old. Plus, upgrading maps for a family member can be a kind gift, as they not be familiar with how to do it.
