If your friends 4.6is has the MK4 Nav CPU...and its not reading the new DVD map discs...I'd reread the instructions for updating the software (to make sure it's being done correctly)...then try the discs again.

BTW...did you burn your friend a new set of map discs...or were you inserting the new discs that you purchased?
