My Excursion OEM radio is picking up static on every station. I swapped antennas with my F150 and no change. Ex antenna is perfectly clear on the truck. I checked cable connections and all are solid. Grounds seem to be okay. Weird thing is when the key is turned back to accessory only, the radio is perfect but turn the key forward to KOEO and I get the annoying static. Anyone know what my problem may be?

 

SOLVED. it was the dash cam/back up cam rear view mirror I installed causing interference.
