If you enjoy traveling off the beaten track, it is sometimes nice to know where you are going. Fortunately, today's car navigation systems feature superb GPS vehicle tracking. They can double as navigation systems and anti-theft devices. Family members can travel along vicariously as they follow your trip on their home computers. Many of them come pre-loaded with maps and features designed to suit all budgets and all levels of use. If you would prefer to maintain the factory look of your dash and add the convenience of a large fold-out GPS monitor, look for an in-dash navigation system. These car GPS systems consist of a car stereo with a built-in monitor, a connection box that contains A/V inputs and outputs, and an external GPS antenna. Plug and play navigation systems are portable units that can be attached to either the windshield or dash. They use a simple cigarette lighter adapter to draw power. This makes them transferable from vehicle to vehicle. Plug and play car GPS systems feature car video screens with touch-tone controls. Many of them are so user-friendly that they can be used without reading the owner's manual. Portable GPS receivers are designed for camping, boating, driving and hiking. If you plan to use a GPS receiver in your car, look for either an in-dash, remote-mount, or plug-and-play system. These portable GPS include features that are uniquely designed specifically for vehicle use. These include such voice prompts, large, bright screens, and built-in speakers. |
