My head unit is a Sony CDX-M630 with only one Aux Audio Input which is now being used for my satellite radio.

I want to install a external DVD/CD/TV Player to a Rearview Mirror monitor. The DVD player only has one video out and one set of audio outs. How do I run audio from the DVD
to my Sony head units Aux input.
Dont really want to use fm modulator. Can both the Xm Radio and DVD share the same audio in. Do I need some kind of
audio switcher? Where to get one? Radio Shack?

 

Yea they can. Goto radioshack and have tell them what you need. They make a cable that will do that easily.

 

Nevermind I found what I was looking for. Its a sony XA-C30 that lets you add 3 more inputs to the aux jack on the reciever.
