Hey Guys new to this forum :)

Wanting to mod my Cars Headunit, Done it but want to improve the setup,

The Mod i have done is this one (

I now want to take it a step further and use a ipod/iphone connector cord (30 Pin) Pinouts

Pin 3 is Line Out Right
Pin 4 is Line Out Left

Not sure on the Ground to use though and im pretty sure Pin 23 is power (only 5V though so would need a resistor in line somewhere)

Would also like the ipod to turn off when the car is turned off Pin 21 does something with that (different resistances do different things ie.1MOhm - Belkin auto adaptor, iPod shuts down automatically when power disconnected Connecting pin 21 to ground with a 1MOhm resistor does stop the ipod when power (i.e. Firewire-12V) is cut.)

Can anybody give me a hand figuring something out?

Thanks in advance :)
