Sirius S50 Hook Up

[oclancasters]

I have a 2007 Mazda 3 and need to know how I can hook up my Sirius S50 to the head unit directly. What are my options? Using the Aux Input only gives me interference from the engine for some reason.

Thanks.

You can still use the AUX input if you like. Just go to Radioshack and pick up a "ground loop isolator." That will fix the interference.

Or order one from Crutchfield. The one from radio shack is RCA-RCA so you'll need adapters whereas the cf one is 3.5mm-3.5mm.

crutchfield is the way to go, will solve all problems!

Wish I'd known that!
