Ready to race!
Did you ever end up figuring this out? I see that you posted your unit for sale in the classifieds...so not super optimistic.
Nope, sadly never got it to work and sold the RCD330. I still think I'd take an RCD330 over my RNS315 though, despite the quirks. I ended up going to THIS 9" Android 8.0 headunit instead, which has it's own different set of quirks. There's no good 100% issue free option for a DynAudio equipped headunit upgrade from the RNS315, aside from the $1550 MIB2 PQ conversion. My R is a garage queen and not a daily driver, so I can tolerate a few quirks that if I had to deal with daily would probably bother me more. So for now the android headunit will work, but once I can blow the cash on the MIB2 I think that's the way I'll go.
