Has anyone installed an AM antenna on your XLR. AM reception is terrible. My Escalade gets good reception but the XLR can hardly receive a local 100K station in a parking deck.
I have a problem with both am and fm and would like to get them to work better but know one seems to know the problem. Cadillac had it back twice and they can not get better reception. They stated all XLR's have the problem.. Any ideas.
