for pioneer, if someone is offering, let's say a 6700 faceplate and they say it can also fit on a 6600, a 670 premier or a 7500 unit, well how do they know that??
Well you have an active internet connection, if you cannto find the number, email them at thier website //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
But I can tell you most likely it wont work. Different data for each unit.
