I’m posting this for my brother in-law. He just bought a 2003 GX470 and would like to upgrade the navigation system to the latest version (I think its version 7.1). Is there anywhere besides the dealership where one can purchase the upgrade DVD? He understands that the 2008 version will be out in October of 2008 but would like to be up-to-date as of now.
Thanks for your help.
