This is the second time my XM antenna has gone bad on my 2010 Toyota Corolla. It took me 4 months to get the dealer to repair it last time because they were not sure what the problem was. I went to the dealer yesterday and the head service writer said I am not the ony one having problems. He was going to check if there is an updated antenna. The shop in the same town that does aftermarket radios also told him that he has been replacing XM antennas under warranty. My friend bought a new GMC truck and his reception was terrible so he cancelled after free period.
