I'm looking to install a Pioneer HU into my 2008 TT V6 with Bose. I'll go Connect2 and AVIC 8000 NEX, but I wonder if anyone has been successful with a Connects2 harness with a similar car setup given some of the past problems from 5 years ago.

Help appreciated.

I suspect this is the harness I need but it's unclear if I have full or half Bose, so can't pick the right model (CTSAD005.2, CTSAD006.2, CTSAD007.2, CTSAD008.2).

Thank you.
