As most people are now aware the OEM "B" model RVC controller in a Touareg has issues with any Firmware above 2XXX. I am thinking about alternative controllers. I personally have paired an RVC Controller from a Tiguan (5N0 907 441) with an RNS510 in my 2006 Jetta and it is now running FW 5238 with no RVC issues (ever). On the strength of that I plan to investigate replacing my Touareg 7L6 907 441 B with an alternative OEMN controller that will happily co-exist with later Firmware versions.
To that end, has anybody attempted to connect a RVC Controller from a 7P Touareg (7N0907441) to an RNS510? I am going start with testing my 5N0 907 441, from the Jetta, see where that takes me.
