So my MS3 came with Sirius and I just installed the Mazda switch box today so I could use my aux jack. Everything works perfect except for one thing. The audio coming in from my AUX jack changes volume based on the speed of the vehicle. ALC is off. It does it whether or not the MP3 player is plugged in to the power. I have a ground loop isolator for when it is plugged in. Sirius, which also goes through the switch box does not change volume. It's not that bad, just a little annoyance.
Anyone have any ideas?
