Originally I was looking at completely replacing my RNS-E unit with a new Pioneer AVH-4200NEX. My main motivations were gaining Bluetooth A2DP and Android Auto. However, I really like the way the OEM Bluetooth function works for calls and the somewhat awkward placement of the head unit in the B7 dash means I likely would not actually use that head unit's Android Auto functionality that often. So now I'm looking at how to add A2DP to the RNS-E.
I'm looking at this Dension unit on Enfig's site -- http://enfigcarstereo.com/DENSION_GWP1AC1.html -- and had some questions.
1. From what I can tell, the Dension GWP1AC1 unit can handle both phone and music streaming. I have the OEM Bluetooth system already installed in the car. I assume the best path forward would be to unplug/remove the OEM module and let the Dension handle everything?
2. Since my RNS-E is already set up with the OEM Bluetooth module, would I need to do anything with via VAG-COM to get the Dension to function completely? I don't currently have a VAG-COM so just trying to see if I need to pick one up for this project or not.
