[x-type] touch screen sat/nav

thanks I have just bought the car at auction the fault was there.
there is also no disc in the sat nav unit the screen just flashes
all the time I have looked at the back off the screen and all the
connections are in place and tight if I select audio or climate ect
the relevent menu comes up most times but flashes to fast for you
to select is it a case for my dealer they are not very helpfull–
