Most modern GPS systems store their maps internally, either on an SD card or in their own system memory. However, the in-dash navigation systems in the Chrysler Pacifica and many other cars use a DVD to store maps. This means you won't be able to simply download updated maps from a website -- but purchasing and using an updated DVD is simple.
Click the "Navteq" button on your MyChrysler owner's page, if you have one. If not, navigate directly to the Navteq order page (see Resources), and select "Built-in, Factory Installed," "Chrysler," "Pacifica," and then the appropriate model year from the pull-down menus at the left of your screen.
Add the map DVD to your cart and complete the checkout procedure. Enter your choice of payment method and delivery address when prompted. When the DVD arrives, prepare to install it in your car.
Open the tailgate of your Pacifica. Lift the cover of the in-floor storage bin, and look for the DVD unit. It's built into the left side of the storage bin.
Eject the old DVD. Gently insert the new DVD, with its label facing upward. The disc will slide into the DVD unit.
Start your Pacifica, and press the "NAV" key at the side of your in-dash display. The navigation system will start. If you haven't previously used the navigation system, you'll be prompted to accept an on-screen disclaimer. Once you've pressed "Accept," you'll be taken to the main Navigation menu. Pressing "NAV" again will toggle between the Navigation menu and Map Viewer.
- Updated DVDs can also be ordered through your dealership, if you prefer not to purchase them online.
- Map-update DVDs incorporate new construction and road changes since the previous year's maps, as well as millions of points of interest across North America.
