With the Auxiliary Tray, you can just take your Sony MP3 player and plug it in whenever you drive. It provides a direct connection, so you don’t have to deal with static or noise. The Auxiliary Tray is lined with anti-slip material to prevent from sliding. If you have a double DIN slot, you can connect the RCA cable to your existing deck’s Aux input, but if you have only a single DIN slot, you need to connect it directly to your Amplifier. Now, you can enjoy your favourite hits in the car.
