Has anyone got one of these CD units in their car? (Sony CDX-CA850)
And do you have any problems with the remote control units not working??

As you can see by the face, if the remote isn't working... there's no f%cken buttons to press! Only thing you can do is put a CD in and listen to it from start to finish at the one volume.
It didn't work properly when I bought the car (my bad for not checking

I've pulled it out, performed a factory defaults reset, changed remote batteries - even 'percussive' maitenance...
Short of going back to Sony, anyone got any clues?
