I have a Audi Allroad 2002 with an Icelink set up for the IPod. I have recently purchased an IPhone and found that the display nor the charging works when docked.
I have looked around and found a firmware update but can not get a clear view of whether that will simply fix the issue or whether there is some creative engineering that I will need to do as well.

Anyone have any experience with Iphone 3GS and Icelink?

 

According to the Dension website, it looks like you need the Gateway 500 for the iPhone to work.
