1. Based on what I've found Avin includes steering wheel integration.
2. Not sure how OPS is done - any details on it? Avin you can add the rear camera, but i assumed you'd still get the PDC warnings
3. True, no DSP - need external amp
4. I currently have a non-OBC, basic radio. Will it actually provide the OBC features?

Loaded up with options I want, I get the Avin to about $920. Dynavin has options too that need to be considered.

Cheers.
