i think i read the thread somewhere having navagation problems
on 2006 is models.

so did i !!

i went to the dealer five times and finally they fixed it..
they thought i had old navigation disk but is wasn't the disk

i just letting you guys know that it is not "navigation DVD" issue

it is GPS antenna/receiver issue that you need to replace.
dealer took two days fix it..

 

Your experience is the exception, not the rule. There have been dozens of '06 owners on this forum that have had their navigation problem solved by replacing the disc with a new one with revised software as recommended by the TSIB.
