I own a 2008 X3 with (or without) these features:

1. No nav
2. No CD changer
3. Already Bluetooth enabled
4. Business CD head unit
5. No satellite radio

I'd like to pick up a DICE unit but I don't know which one is best for me. Here's what I'm looking for:

1. To use my steering wheel controls to control the iPod
2. Discreet and seamless installation (no wires showing or iPod just laying about)
3. I'm not interested in Bluetooth or satellite radio connectivity

I currently own a 6th gen iPod but I might buy a new iPhone when I upgrade my phone at the end of the year. I haven't decided if I want to stick with my Android phone or not.

What is the best option for me?
