Pin 11 should have a 1K resistor between it and pin 21, and also a jumper wire from pin 11's end of the resistor to Pin 30 of the dock. I've been using this for awhile and it works fine.

actually from pin 21-1/2/30 is 357K, 21-11 is 11.65M.

11 go ground 1/2/15/16/30 I'm not sure which it would be connected to, but I'm hoping for a short on these. they're all measured around 11.25M.

Pins 1,2,15,16,29 and 30 are all "ground", they are all connected to the same trace inside the ipod/iphone, so you can use any of them for ground.

pin21 to common = 375k
pin11 to common = 11.25M
pin21 to pin 11 = 11.65M

anyway, I found this "thread" (it's really only one post) and he says his bluetooth audio adapter that I will assume is "iPhone certified" had a 95k resistance between the accessory pin (21) and ground.

No se puede controlar el volumen cuando esta conectado a los altavoces
Juaquin, I think the lineout of these devices is meant to be controlled by an amp/receiver/whatever. On the IPhone dock's lineout, the volume cannot be controlled by the phone. This is because of the expectation that an amp will be hooked up. You could always just put a volume control of your own on there (sliding variable resistor like some headphones have?).

Connect pins 1, 15 and 21 to pin 11. Use 2, 3 and 4 for line out.

I checked my iPod nano 1G, iPod 3G, iPod 4G click wheel, iPod 4G photo and iPhone 2G. They all have continuity between pins 1, 2, 15, 16, 29 and 30. I think it's safe to say the rest of the iPod and iPhone models follow the same scheme, but if you want to be a real stickler, you can check it out yourself.

Un tio que quiero lo mismo que yo, que aparezca el volumen
Let me ask some stupid stuff..
I've a USB (to Belkin micro car charger)/ 3,5 mm Stereo (Input to head unit/ auxgate connect) to dock cable which i bought in the shop. I'm using an iPhone 3g with FW 3.1.3.
I only get a line out signal and the volume slider in the iphone disappears as connecting the cable. If the iPhone is connected to the original Apple Dock i've the volume slider which i like to have also in car.
I bypass my head unit and connect to an i-sotec auxgate connect. So volume is only controlled by the input device - so i need the volume slider of the iphone in the car.
I opened the dock connect cable and found a resistor and measured 67.8 k OHM. Regarding this site Apple iPod - iPhone dock Connector Pinout - AllPinouts i need a 1k OHM resistor to get the volume slider?
My requirements:
I need the volume slider.
I don't want to see the "not copmpatible" message.

So what is the right resistor in my case?
