So I used a LOC to keep my original radio for my 2012 Pathfinder. At first I was getting a buzzing noise that increased as i accelerated and decreased as decelerrated. I fixed that by ungrounding my LOC.
Now I have a high pitched noise that rises regardless of whether Im accelerating or not. It goes up and down at a steady pace. I also get waves on my display. Almost like its picking up a frequency or something. They happen simultaneously. Weird thing is, I never know when its going to start . They could start after 5 mins of driving or an hour of driving. Its different every time. Any ideas?
