So maybe you have any real life photos of the cable (of connector in particularly) ?

I wonder what the fifth pin is for...

Have the same problem on friends unit, only USB wire was soldered! And there are 5 pins, so i still haven't fixed usb wire!

Maybe someone have any pics of stock usb cable wiring?

Thanks! Great service manual!

So it seems that pinout is

1. +5V

2. D-

3. D+

4. not used

5. Ground

But in my photo you can clearly see that 4th pin had something welded to it... but in service manual it hasn't!

What could it be?

Hi everyone!

So my friend tore off USB cable from F700bt head unit while removing it to connect amp wires!

I took HU apart and found the connector, but there are five pins on it and they are not marked so i don't how to correctly solder USB cable back... Because he lost the original cable, i have to use cut off USB cable extender!

Maybe someone knows what is the right order of wires? Some photos maybe?

four wires of USB are +5V, D+, D-, Ground, but which pins do they connect to?

And what is the fifth pin? could it be just shielding or second ground?

P.S. Sorry my English isn't good!
