Unit vs. unit (if video is not a main concern) the CDA9887 is an all around better sounding unit. I have the CDA9887 in my Corolla and the IVAW205 w/ blackbird in my wifes Camry. They both sound great, but the controlls on the CDA9887 (if your a tweaker) makes all the difference in the world. That and the 24 bit burr brown DA converter doesn't hurt much either. If you think you might add the PXAH701 processor, that would (in my opinion) put the IVAW205 ahead of the CDA9887 in sound quality and system flexibility. You might also want to consider the IVAW505...pretty much the same as the 205 but with a bigger screen (7" vs. 6.5") and a usb input.
