Best Car In-Dash Navigation GPS Units in 2012

In-dash navigation GPS units are very useful for those who drive a lot, not to mention that they are easy-to-use, and you can see different routes when you want to go from point A to point B.

Manufacturers have combined GPS units with car stereos making them an all-in-one solution which offers the high quality audio and a navigation system.

The most important feature that you should look about when you want to buy an in-dash navigation GPS unit is the GPS map database and if you have the option to update it. Usually, they support map updates by CD or USB thumb drive.

Other things to consider: accuracy, speed and ease of use (important to your overall enjoyment), screen size and resolution (the bigger the better), points of interest (it will help you find various restaurants, hotels, gas stations, even ATMs), real-time traffic data (may require subscriptions to different services), and touch screen controls.
