and if not then you can buy a Denison Ice Link & plug it into the cd changer socket on the back of the HU.
then you can control playlists etc from the cd player or Steering wheel controls & charges the iPod too.. Works a treat, but cost a fair bit more than a tenner.
(never knew there was an AUX slot on the back of the stereo ???... i must pay more attention!! lol)
i got a dension as i never knew about the aux input and to be honest i never spotted it when i fitted the dension blue plug into the back of the radio..
(any one got any pics of where the input is to save me ripping my head unit out and having a look curiosity is going to get the better of me)
