Thanks, same here - I already have the pmx 2 headunit , and I have ordered the pmx 1r to go were the original radio controls go. I looked at the pmx-8bb, but it keeps stating everywhere use the PMX-8DH controller?, but can use the pmx 1r added with 3 way cord. Let me know if you found out that the pmx 1r can be used byitself with the pmx-8bb. by the Way the pmx 1r will be a tight fit where the stock radio controls are now- if that's where your mounting it. I like the way the pmx2 is working so far with the features, but it will not fit at all where the stock radio controls go, so that why I'm getting the pmx 1r to control the pmx 2
