iphone 3g- dock pins with mic and track switching
I've got complicated problem (at least for me 'cause I am noob at this).
Btw. forgive my english. I come from Poland.
I want to connect my iphone by dock to radio in my car so I could listen music. But one function is missing in line out connection.
Switching tracks (like using doubble tap on your earphones pilot).
Is there any way to find pins which are responsible for that? (external accesories like speakers with dock for iphone have abilities to change songs through dock connection).
Taping tags are caused by fusing ground with microphone- (third ring and sleeve in jack):
Apple iPhone headphone jack adapter pinout and wiring @ pinouts.ru
I found complete description of dock pinouts:
Apple iPod, iPad and iPhone dock Connector Pinout - AllPinouts
but I can't find microphone pin!!!
Can anyone help me with that?
