Hey guys i have a pioneer HU with the sirius hook up and i have a magnetic square antenna mounted on my roof and within the past few days my HU keeps saying NO ANTENNA and i looked at the antenna and its not cracked and the wire is in good shape. so tonight i took my dash apart to get to the sirius box where it plugs in. I removed it and then plugged it back in and it worked for about 30 seconds and then went out and had the same "no antenna" message. These past few days have been really rainy and cloudy so im thinking maybe that has something to do with it? anybody have/had this problem? thanks
