How to Fix the Toyota Sienna's Navigation

By Chanel Adams

Your Toyota Sienna should come installed with a factory navigation system that shows points of interest, turn-by-turn directions and downloaded maps. It might also include features such as hands-free calling and Bluetooth wireless technology. If you encounter problems with your Toyota navigation system, you should reset it. Resetting erases all of the memory on your navigation system, including any personal information.

Turn on the navigation system. Press the "Setup" button on the right side of the unit.

Select "General" from the top right side of the touch-screen menu.

Press the "Down" button. Choose "Delete Personal Data."

Select "Delete Personal Data" again when prompted. Touch "Yes" to confirm your choice. Your navigation system will restore itself to its factory settings.
