Finally found that cable from hall road for 2.5k
now usb and ipod option both are working.
But the worst part was I ask that guy to install the system in my car he installed the system along with that cable and at the end he put all the leftover back cable from my pioneer DVD player to hus box. Since I was keeping an eye on him, I said why r u taking those cable. He said these were useless.
I asked show me. Thise cablr contains different connectors. Some gps some camera many other cables too. I ask I need it so give them back to me 
How clever those guys are later he might sell them for 2k for each connector like I was robbed previously for that USB cable.
So a lesson for all is. Never trust these mechanics. Always stand on their head during installations and carefully check them while leaving.
