Color: Black Material: Plastic and metal Allows you to connect an external o source (such as a portable MP3 player, laptop, etc.) via the CD changer jack of all head units from 1999 and newer. The externally connected o source can be controlled directly via a button on the car radios. Works perfectly for a Car PC or laptop DVD player. It is a replacement for the CA-C1AX/CA-C2AX connector, without limitations in function and quality. The adapter allows an external o source (e.g., DVD player, media players, laptops, MP3 and MP4 players, etc.) to be connected to a radio with a changer socket. This allows for perfect sound in your car. Notes: To use this accessory, the head unit manual must indicate an AUX input option using a CA-C1AX adapter. Please check your user manual and confirm compatibility before purchasing. This is not an original cable. Your car stereo will not recognize or detect the cable after plugging it in. You will need to manually activate the correct source, which is labeled as EXT IN, via the menu settings for o input from this adapter (do not use AUX). Then use the button to select the source. If unsure, please refer to the user manual. Package contains: 1 x Aux In Cable Only the above package content is included; other products are not included.
