I am also interested in adding the navigation feature to my 06 GS430 send information to tahayaxuarez@bellsouth.net
Thanks, Tahaya
The dealer will want to put you in a GS with factory nav. A dealer will not install a factory nav. If you want a factory nav for your GS let me know.
How much to get factory nav for an 06 gs300?
Yes, The navs are available. Please leave your email address. I can point you in the right direction.
