I have a 2007 TL running 4.55 version of the NAVI. I will be travelling to Canada, I ordered the 4.62 version for the Canadian disk but I will not get it until March. A friend mine loaned me his DVD but it is a 4.33 version.
I tried inserting the 4.33 version with the Canadian database but it will not run since I have an updated firmware. Does anyone know how I can make this work?

Help would be really appreciated.

 

try going to your dealer and see if there is anything they can do for you.

 

How far north are you going into Canada? my original 05 TL navi disc works everywhere I've been in Canada, B.C.
