Ground loop isolator, isolated half my audio?
So I get a whine, it's not terribly loud, and with my music at a decent level I can't hear it.
However, if I'm not listening to music, but say navigation directions, or a road trip and someone isn't blasting a DVD, then you hear it.
So I had the install shop throw on a ground loop isolator. No more whine! Half the sound gone =(
So we had to remove it. Do you think it was a bad isolator? Are some isolators better? Any other solution, other than trying different locations for the ground?
It's not terrible, but it's annoying if I'm wanting to use the navigation
