any recommended place to have the stock head unit checked?  my location is cyberjaya.  i want to make sure its fine before i use it.  for example, is the cdplayer still good, no stuck cd... so i need to have someone check it.

btw in relation to this thread, yes i plan to connect an MP3 player as well, as nobody much uses audio CD nowadays.  don't wanna buy a head unit just for very rare use.
