I was just wondering if any of you guys have had experience with the new pioneer H/U's in conjunction with the sir-pnr1 (specifically the DEH-P880PRS and the DEH-P780mp). My current H/U is the DEH-P670mp and I am looking to upgrade to one that will actually function fully with the sirius tuner. Pinoeers website says that those two models have full control with the sirius tuner, but I would like 2nd and 3rd opinions if possible. My current h/u has major limitations of the information that is available with sat. radio (song title, station name, artist etc...) and I would like to know if the new ones have that same limitation or not? Thanks...
