I had the DNX8120 in my 2.7T and the antenna was placed under the dash directly above the instrument cluster. This setup performed very well. But I would still prefer to use the factor antenna if possible.
When I installed my RNS-E, I tapped into the fin antenna via the OnStar module which is located under the front passenger footwell. I don't re-call the part number of the lead needed, but I found it easily at a local VW dealer. Do a search for installs on audiforum.us/rns-e/ - meantime, if i find the link, I'll edit here
