I was messing with the hack menu and have got it into a different load version by accident. i was wondering if anyone can post me a picture of their load hack menu, i remembered i saw 3 U.S. map listing under the load screen and i don't remember what it was that i press on so when i do it already lock me out of the system and i couldnt do much more. so i hope some that still have the hack menu working and post me some picture so i can finally get my nav working again thanks

 

If it is truly locked try rebooting.
Go to the trunk take lift rear lid which has jack etc.On the right hand side there is a recess with a door on it.Remove the door thats where the sat nav drive lives.On the unit is a black button press and move to the left at the same time.This will release you nav disc.After it has popped out put it back in and let the system reboot.Hopefully it will clear it and take you back to the beginning.
You need to have the ignition on for the nav disc to be released.

Putting the original DVD back in will also fix many things. I run a Gen 5 DVD and I needed to put my Gen 4 in after I got a new battery. It re-runs the software update and then I can switch back the the gen 5 disk
