How to Update My In-Dash GPS
GPS updates for in-dash navigational systems are usually available once a year through certain dealerships. Roads aren't updated that often, making navigational DVDs available any sooner than once a year difficult. Once you have gotten a new navigational DVD from your car's dealership you can easily update the system with a new DVD in several minutes, giving you the latest road maps available for any GPS in-dash navigational system.

Tips & Warnings
Some new in-dash GPS units installed in the console or dash are combined with the vehicle's audio system, and allow you to insert the new navigational DVD into the CD/DVD slot without having to remove a cover to gain access.
