Does anyone have any experience with steering wheel control adapters and aftermarket radios like the Pioneers, Alpines and Clarions?

My research shows that there are a few available:

NatTV MOST integration for Bose: I hear that only the volume control works

Axxess: the web site says that it has not been tested with Porsche

PAC SWI-RC: No mention of Porsche support on their web-site

PAC SWI-CAN: Can bus adapter (which is needed) but not tested on Porsche according to their web site.

iDatalink Maestro: No mention of Porsche on their web site

Paser Unican Plus CAN Intelligent+ from Mr. Canbus: States that it works but I have no confirmation.

ANyone know a sure fire solution? I want to get the Clarion ns702.

Thanks

 

I was wondering if anyone has a working solution for a Porsche 987.2? My car's steering wheel controls currently do not operate the Alpine INE-W925R head unit and I am looking for a solution. Seems that Paser is most likely to work, but would like to hear a confirmation from anybody that tried it.
Thanks!
