If anyone can answer any of these questions I would appreciate it.

Please help with a few questions in regards to the radio and possible addition of CD changer for a 2003 Boxster.
Radio CDR23- 6611

Questions:
1. To add a CDC-4, is there any programming required with "Dealer Type Equipment such as the PIWIS?"

2. Does CDC-4 control and audio go through the fiber optic cable to the CCDR23?

3. Are the fiber optic cable connectors "ST" connectors?

4. Is there a way to input an I-pod or similar mp3 player into the CDR23-6611? and oviously select the I-pod as an input.

Thanks for your help
