I just finished making this cable. It's a female iPod connector that splits to micro USB and 3.5 mm headphones plug. I was tired of everyone making just iPhone compatible stereos but never giving ever other phone a way of charging without a separate wall charger. If they have a iPod dock they could easily put USB on the device also. Anyway here are the pics of the first prototype I made. Works flawlessly and charges as A/C.

How to make an iPod dock cable

The first thing I did was buy these 3 cables.

An iPod dock extension cable http://www.ebay.com/itm/30069026148...NX:IT&_trksid=p3984.m1497.l2649#ht_2757wt_698 ,

an 3.5mm stereo cable http://www.monoprice.com/products/p...d=10218&cs_id=1021802&p_id=644&seq=1&format=2 ,

and a micro usb cable http://www.monoprice.com/products/p...=10303&cs_id=1030307&p_id=4868&seq=1&format=2 . I then cut the iPod dock cable in half. Set the female end to the side. I opened up the male end to verify the color of the wiring to which pin they were attached to. What you need is 5 wires from the iPod dock connector. You need is the wires for either pin 1 or 2( audio GND) , pin 3(Audio R) , pin 4 (Audio L) , pin 16(USB GND), and pin 23 (USB +5VDC).

Now that you know what colors you need from the male end of the iPod connector, strip back about 4 inches of the outside jacket on the female ends cable you set aside. What I did was twist the outside drain/ground mesh together then separate the 5 wires you need from the cable. I then took the remaining wires put them in a line and cut them on a diagonal starting at about an inch. This way each wire is shorter than the next. Now twist them back together and put a piece of heat shrink over them. Now you should have the outside drain/ground and the 5 other wires left. Now cut the other 2 cables however long you want them . I made the 3.5 mm cable about 8 inches longer because it has to reach the top of your phone and the micro USB goes only to the side. Now strip back about 4 inches of the outside jacket of the other 2 cables. Do the same think and twist the outside drain/ground together if the cable has it. Now you should have the outside Drain/Ground, red, and white wires for the 3.5mm stereo cable. You should also have the outside drain/ground, red, white, green, and black on your micro USB cable. I started with applying heat shrink over the drain/ground for the 3.5mm stereo cable. Now solder the newly heat shrunk ground from the 3.5mm stereo cable to the wire that was going to pin 1or 2 (audio gnd) on your iPod cable. Now solder the red wire from the stereo cable to the wire from pin 3 (audio R). Then solder the white wire from the stereo cable to the wire from pin 4 (audio L). Now grab the micro USB cable. Cut the wires for the green and white wires from the micro USB to about an inch and solder them together. This will all the phone to charge at full A/C not at USB. Then solder the red wire to the wire going to pin 23 (+5 VDC). Next solder the black wire to the wire from pin 16 (USB gnd). Last solder the drain/ground from the iPod cable to the drain/ground of the micro usb.

3.5mm Stereo cable-

Red- Pin 3 (audio R)

White- Pin 4 (audio L)

GND- Pin 1or 2 (audio GND)

Micro USB-

Red- Pin 23 (+5 VDC)

Black- Pin 16(USB GND)

White-Green(Solder together for A/C charging)

Drain/GND(USB)- Drain/GND(iPod)

I ended up cutting the wires to about 2 inches total length before soldering and applied heat shrink over all the solders then a larger heat shrink over the whole place where all the splices took place. I also staggered the splices to make that area as small as possible. I should have taken pictures but didn’t. If/when I make another one I will take pics.
