Cd Changer And Harman/kardon Drive And Play

[drez]

Hello all. New to the forum and was wondering if anybody has had success wiring their Drive and Play so that you can use the CD button on the head unit. I am currently using it via wired FM and it isnt that great. I am not concerned about being able to use the CD changer. BTW, I am driving a 1999 RX 300 non-Nakimichi.

Thanks.
