The  pin of the infrared sensor connected to its metallic body will be the GND pin.
Heat sink can be connected to 7805 regulator IC to avoid over heating.
You can connect an external 6V battery to the input of 7805 IC so that even the power goes,the player continues playing .
A wire of 10cm length to be connected at the hole in the FM board.
If you want to connect it to your car audio system just give the audio out of the circuit to AUX in of the car stereo player.
