Hey guys,
this thread has been a huge blessing!
I have an Alpine head unit with the older type AI-Net connectors and could not find an iphone compatible wire so i decided to modify the one i bought on ebay which has a headphone jack AND an ipod connecter connected to it.
Now the way i got it, the ipod connector doesnt do a single thing when connected to the iphone and the headphone jack works, the cool thing is that i can take calls through it very nicely.
So i decided to cut off the ipod connecter and modify it,
here's what i'm planning to do:
Iphone plug to AI NET:
Pin 19,20 Iphone plug to AI net Pin 7 Battery (do pins 19 and 20 both have to be connected?)
Pin 29,30 Iphone plug to AI net Pin 8 Power Supply Ground (Same question as above, do both pins need to be done or is either one fine?)
Pin 3 iphone plug to Ai net Pin 4 Right Signal
Pin 4 Iphone plug to AI net Pin 6 Left Signal
Pin 2 Iphone plug to AI net Pin 5 Signal Ground
Use 66kohm from pin 21 (ACC) to pin 1 (GND)
Use a tiny short piece of wire soldered from pin 11 to pin 15
Can anyone please give me a confirmation if this looks good? i have attached the pinout of the AI NET connector.
My other question is, has anyone thought about using a switch to toggle between the Line Out on the Iphone and a Headphone jack which woiuld also be connected to your radio to be able to take calls on the phone? This way you would listen to music through the LO but hit the switch when getting calls.
