The dreaded high pitch alternator whine when using the aux stereo jack is back.
I used a plug in filter and it mostly elminated the problem. For some reason it returned. When the RPMs go up the whine gets louder. I took it to a sound shop and they didn' know what to do. Made another pit stop and they tried a different filter. On a test ride the whine was gone. Pay the shop (they were closing) get in drive home and.....same as before. They're closed today.
If anyone has figured out a way to completely get rid of this short of just replacing the whole head unit and not dealing with aux please shed some light.
It sucks!!!
