Hello,

I have a factory ACM installed as well as the factory Sat radio. The ACM was already installed, however I purchased a factory sat radio kit.

The sat radio kit did not come with the power harness so I ordered a generic one from ebay and hardwired it to the nav radio unit. Everything is working well except for a noise issue.

The issue is that I have a bad alternator whine noise through the speakers. I grounded the unit to the car via the bolt that holds the battery holder against the body. I also removed the paint down to bear metal In this location so I would have a good ground for the unit.

Never less after everything was connected, I have a bad whine noise. Any suggestions?
