I have a 6.1 nav dvd in my 2007 Sequoia and I'm trying to burn my own DL DVD with the 5.1 loading.kwi. Do I need the loading.kwi specifically for a Sequoia or will any Toyota work? I'm ready to hit the used car lots with $50 and my laptop so I can copy the file. I've searched for days and all of the posts end up pointing to a broken or corrupt download link.
