I get perfect reception on fm radio stations but some days the am stations always sound like so much static. i think the antenea is in the rear window and i have a 20% tint on my back windows. could the tint be interfering with the antenea
Metal tint does interfere but your antenna is on the outside so that shouldnt make a difference. I get horrible AM reception as well compared to my two other stock radios (ford). I think these radios are not very good.
How in the world could you upgrade that roof antenna??
