I unplugged the battery earlier today and when it back in.

I thought I had both the nav code and the radio code.

The nav code worked, but I must have the wrong radio code.

The rest of my menus seem to be missing. Will they reappear when the radio is enabled?

Here is what the screen looks like now.

 

I got the radio unlocked, the other menus are still MIA.

How do I get them back?
ok, I never knew this, I guess my car had the navi hack to get all those menus, mpg, fan control etc..
Do I have to hack it again?

 

Yes, you will need to boot it with the hacked disc and then swap out discs once booted.

 

I got V 3.5
I'm searching all over to look for the files I need. Many of the links are dead.

Is there a better source to find everything?
