Has anyone come up with a solution to the poor am antenna reception in the coupe models?
I see many people have upgraded their radios but none have said if the upgraded radio has solved the reception problem.
I have the new radio and the am reception is still bad for my local am stations, could the antenna module be bad and exactly what does the module do?
Also, could you unplug the cable from the module and add a small antenna to the end of that cable? The new antenna would be covered by the plastic window trim.

Thank you for your help.
