Hey Tom; I just finish installing my DICE w/ radio interface. So far everything seems to be working but I have a couple of questions: 1. With the Radio interface do I need to keep a cd in the changer because if I remove either the CD cassette or all the cd the radio just tells me that Cassette empty and dosent play the IPOD. 2. If I leave a CD in the CD cassette it recognizes that cd number and I have to press the toggle button and it will quickly flash the number 1-6 so I can then toggle the playlist. is this normal?
