Question: E85 with Sat Nav / DSP / CD Changer

[Z4M30i]

Hi All, there are many articles and I'm sorry if this is something that has been discussed multiple times but:

We have a:

2003 E85
Sat Nav
CD Changer
DSP

Looking to:

Connect iPhone/aux
Not important but would be nice to have details show on the Sat Nav screen (name, artist etc)

1) What are the easiest installation / cheapest options?

2) Where can I purchase these from? (I've found a few on eBay but they aren't compatible with DSP, any part names / links would be appreciated)

look at an Intravee + Ipod..Works well..

Do pop up second hand every now and then..

Not sure about the DSP though..
