Contrary to all who are upgrading from Stock HU to better ones, i am planning to go the other way round and trying to install a Stock HU in the Punto Active. My existing player [Sony] stopped reading CDs and was only left with Aux and radio. The older Active variant had a completely black dashboard and the idea of getting the OE player and masking it with black color came to my mind. The problem started when i connected to the ISO, the player plays for 20 mins and turns off. I am know nothing about electronics but did give a shot in understanding things behind the engineering. I might be wrong but, i see that there is no wire to the switch [Ignition /Cut off] and hence the player might not at all be knowing whether the cars ignition is turned ON/OFF Need help to solve this mistery Also i noticed that my Sony old player was recognizing the ignition on/off. It only turned ON when the Key is in MAR position or the car is running. When looking into connector used for Sony, the red and black wires are connected to red and black wires of ISO, but the yellow wire of connector was connected to blue wire of ISO.
