To update GPS maps for a Toyota, you need a self-install DVD. Alternatively, you can visit a Toyota dealer who can update the GPS maps, depending on the vehicle model.
Maps in a GPS system are often up-to-date to the year of the vehicle model. However, over time, they become incomplete as roads and points of interest are built, closed or changed. Before starting the update, it is vital to take into account the vehicle model, year and options package for the GPS update.
Depending on the vehicle model, you can find your Toyota GPS by locating the map DVD, which is often placed in the trunk, under the seat or in the car's glove compartment. This is followed by pressing Menu and then pressing the DVD button on the touch screen. On other models, you can find this information by pressing the NAVI button followed by Map Data on the touch screen.
After accessing the map information, you can contact Toyota for prices of the map updates. Updates for a built-in navigation system or a GPS system that uses a hard drive are only available from dealers or from Toyota. However, you can collect the updated DVD to install the updates at your convenience.
It makes sense to update maps regularly to stay up to date with changes made to roads and points of interest. New maps are available annually, but they don't update automatically.
