When I initially start my car up and drive I have a very distorted/weak AM FM radio signal. I can drive for about 20 minutes then it is back to normal. This will happen no matter where I am in the city. I have made no mods or tinted rear window. This is a stock head unit with no NAV. The XM signal is fine. Only the AM FM is effected. Any thoughts for my issue ? thanks

I'm having the same issue in a 2011 sedan but it never goes away always static. Anyone want to chime in?
