Given the quality of the maps from Apple and Google, we're inclined to agree that they are good enough for most people. You already have one: Factory-navigation skeptics argue that smartphones are an alternative to an expensive factory system, noting that phones already have a map application, and that's all you really need. Most portable systems do not have these restrictions. Use limitations: For safety reasons, some factory navigation systems do not let you input directions while the car is moving, which could be frustrating if you want your passenger to press the buttons. If you want to update the maps, you need to purchase a memory card or, for an older vehicle, a DVD. Updates: The maps on factory systems are typically as current as the vehicle's model year. In some cases, you cannot get a navigation system unless you choose one of the more expensive trim levels. But in many cases, automakers bundle navigation with other accessories and call it a 'Tech' or 'Premium' package, which can cost more than $4,000 in some luxury vehicles. A la carte navigation systems start around $500 in new cars. After three to five years, used-car shoppers are less interested in high-tech features, especially if they look dated and lack the capabilities of tech in newer cars, according to Edmunds analysts.Ĭost: Prices for factory navigation are all over the map, and there doesn't seem to be any logic to them. Resale value: Factory navigation systems may improve a car's resale value but only for a short time. Thieves will have a much harder time stealing a factory navigation system than a smartphone or a portable unit that's stuck to the windshield with a suction cup. Theft resistant: A portable navigation system can draw the attention of thieves. Extended warranties might or might not include the navigation system.

If anything goes wrong with the system, you can take it to any factory dealership for a free repair within the warranty period. Warranty coverage: Since the factory navigation system is part of the vehicle, it is covered by the bumper-to-bumper warranty. They're especially handy for those who frequently travel to places with limited cellphone service. This means that you can use such factory features as voice activation and other interface methods such as control knobs or on-screen buttons.īetter GPS signal: In-car navigation systems are satellite-based and should always have a signal, even in the most remote of places. These systems typically have larger screens that are mounted in well-thought-out locations and are designed to work seamlessly with the vehicle. Integration: The factory-installed navigation system will appeal to the car buyer who likes a clean, high-tech, integrated look.
