ginnnts Posted March 7, 2012 Report Share Posted March 7, 2012 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! Quote Link to post Share on other sites

ginnnts Posted March 8, 2012 Author Report Share Posted March 8, 2012 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? Quote Link to post Share on other sites
