[photoeos5]

Hi, I was wondering if it was possible for me to connecte my Alpine K7 player to my cars remote without buying a special cable (fyi : cable costs 90euros Oo).
My Alpines SN : AL7583P0330859
and there's also : R20330859A

Also if someone has info on this radio could help, I bought it off ebay a couple years back and the only extra entry I understand is the CD charger lol. Thank's a lot for the info
