Especially for all those brothers who still couldn't understand.
By the name of Cassete car Kit, its easily available in the market. Rs. 150/- to Rs. 300/-...... 300 wali is geniune one with big head. U can jack it into anything like PSP, Cell fone, Mp3, Laptop etc..... Jis chiz me headfone ya speaker lagne ka jack ho usme ye lag jati hay aur cassete ko car k player me daal dain.... Phir ap apne gadget par jo b play karen ge, u wud hear it on car speaker. No matter u play video, audio or anything....
During driving i connect it to my cell, insert cassete into the player and i can listen to the calls on my car speakers 
its very useful thing
