I have the Custom Auto Sound radio in my 66 mustang , its the older style radio they made with the cassette player. I know I cant use the cassette part anymore , but the radio works good. Im not too savvy with todays radio technology , but my question is , is there any way to make my radio to be able to play MP3's from my phone or Ipod ? I really don't want to have to buy a whole new radio if I dont have to. Any suggestions are greatly appreciated. I did see something on ebay called a wireless audio transmitter for smartphone anybody know about these ?
