looking to borrow a rev 9.1 disc for a gen 2/3 nav system. i was in the service menu and hit the wrong soft button and now get half english half japanese telling me to insert the proper program disc. what i have found online suggest a new disc with new firmware version will force it to correct this problem. i would really like to try before shelling out $300 for a nav disc.
i am in north alabama and would prefer local. just need to insert the disc to see if it will work. i do not want any copies as they cannot be read by the 2002 nav head unit.
