Forgive my ignorance but I am posting to ask if there are shared files which I can access to download and burn to dvd for upgrading the navigation dvd in my 2004 Toyota Sienna which has a generation 2/3 system? It is my understanding that the latest release for my system is Version 9.1. Also, if this is possible to do what will I need to do this?
Thanks for any and all help.
