Welcome John,

The Nav unit is made to not ber operated while the vehicle is moving. Toyota calls this a safety feature. However, if you are tech savvy, you can make the Nav system work while moving. You will have to create a map DVD using your current disk, then change 1 file to an older version to make this work. There are some posts here that explain it very well.

The dealer actually can change the recirc mode so that is doesn't come on by default. However, I believe the recirc mode comes on regardless if you select the Auto function.

Additionally, you can change the setup of the unlocking the doors o the car. I changed it so that when I open the drivers door, all of the doors unlock instead of just the drivers door. This helps to save me from pushing the unlock button on the fob/door to unlock the doors for my family. Again, there is a thread on this site discussing this. Sorry, I do not have the link to post it here.

Congratulations on getting a TCH. Be prepared to find yourself watching the nav screen for your milage and make sure you keep your eyes on the road as much as possible
