Nah, that'd restrict it too much...I've used different model remotes with the HU, it's a pioneer thing. The only issue I'd have is that I couldn't use all the features, but really all I want from it is volume control, track skipping, and the ATT function.
If need be though....it's a Premier 750. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
