I put in a Panasonic (CQ-8303U) radio in not too long ago. I noticed that when I plug in my Sirius Sat radio into the Aux jack that it has a lot of interference, and the more I turn it up, the louder it gets. I can plug anything else in like Mp3 player and it works fine. I had to go out and buy this antina splitter to hook my Sat radio up to my radio without a lot of static going through the fm transmitter. It works fine like that, that is how I have had it set up for a while, but it’s not as clear as I would like it to be. My question is why would it have so much interference through the AUX jack?
