I just finished my non-navi to navi install, everything is working normally.

The problem, Once I begin to drive my displayed vehicle position starts to fall behind. I have larger wheels on the TL. I'm assuming this is the probelm. Is there a adjustment for wheel size? and how do I access the Diagnostic Menu I keep reading about? Thanks for your help guys.

 

Found it. Sorry guys.

Admin you can delete this thread.

 

it will automatically adjust itself the longer you drive.
