Pioneer Stalk Adaptor Not working?

[Schweppy]

Worked fine on my 182cup and on my ph1 172 but since putting it in my 172cup it doesnt work?!?!? It has replaced the same Tunerlist stereo every time so i dont see a problem.

Im sure I remember it not working for a while in my other cars and then having to do something but ive forgotten....

same problem I had with my Alpine (display and stalk lead), it would work, then not, then work again.

sometimes within minutes it would change its mind.

so long as all the connections are good, I cant see why this would happen but hey, ask MT AAudio, they might have an idea (traders on here I think)
