Attempted to install hybrid 2011 Generation 5 Navigation DVD with loading kiwi from 5. for 2007 IS 350. Removed original DVD,pulled Radio 1 fuse and waited 5 minutes before reinserting Radio Fuse 1. Turned on car and new maps were loaded but unable to access service menu with the "Menu, Volume, Upper Left, Lower Left, Upper Left and Lower Left". Turned off car and started it up but "Check VSC" mssg came up and unable to start car. However, was able to access service menu. Did not change anything but tried to restart car. After many failed attempts and instances when navigation didn't even load up, was finally able to have the navigation turn on long enough to eject Hybrid DVD and reinstall original 6.1 DVD. After several repeated failed attempts to start the car, the navigation screen won't even turn on now, power in the car won't stay on long enough to close windows or sunroof. Tried resetting by removing negative terminal of battery opening and closing gas tank cover to no avail.
This was totally not worth trying to fix the problem of not being able to have access to the navi while I'm driving. Preparing to shamefully tow the car back to dealer on my own dime. Feeling sick to my stomach. Please don't judge but any help or insight would be greatly appreciated.
