I don't have factory bluetooth. I don't know the answer to that question. Yes, I did the install, not difficult, great directions and great technical support at least at that time (several years go). It took a about 4 hours because my CD player was in the rear. It has worked flawlessly, well worth it. The Dynavin was not available then. I have looked at the the Dynavin. For me it doesn't offer enough value. I would go that route if my radio failed. I suggest you weigh the benefits of each against the difficulty and time it takes to install each. If I were going to a Dynavin in a few months I don't think I would do anything. I would save the money and go to the Dynavin sooner.
