I'm planning on having the same set up, although there are a few more things i want to do:
1. Use my phone via bluetooth and the front end, will the built in bluetooth in the mac mini work for phone purposes? or do i have to get one of those dongles?
2. I want to be able to listen and control the radio through the mac mini, all i could find was that am/fm tuner on the mp3carstore:
http://store.mp3car.com/HQCT_High_Quality_Car_Tuner_FM_Radio_p/com-009.htm which is pretty pricy, 150$, and it looks like it's supposed to be inside a computer case. Are there any cheap external alternatives?
Thanks in advance!
