I have sent this guy the V22 CD and he loaded it. Now everything is blue and white in the menu. Everything is in the menu besides navigation.

He also has 'CODE' in the screen where he can click on.

Can I try another flash with V17.1 from Index of /web/Descargas ? Will the mk3 flash back from V22 to V17.1?

Can the navigation became unrepairable by flashed with the V32 CD?

I will tell him to put disconnect the accu.
