s1xsp33d Posted January 21, 2009 Report Share Posted January 21, 2009 For some reason my XM drops connection when driving under bridges (short overpasses on the highway), and even some road signs and sometimes even when there is nothing over my car. Do i maybe have a bad antenna, or is there some sort of diagnostics screen on the avic for XM? This is really bothersome and a bit ridiculous IMO. I could understand sitting under a bridge or in a garage, but when there is nothing around me? c'mon. Quote Link to post Share on other sites

I find the lower the antenna is to the ground, the greater likelihood there is for signal loss. As a test perhaps you should attach your antenna to the roof of the car and see if your problem goes away. If it does then you know what your problem is. Regarding diagnostic screen for the XM radio. I'm afraid I haven't seen one. Quote Link to post Share on other sites
s1xsp33d Posted February 18, 2009 Author Report Share Posted February 18, 2009 i have the antenna sitting in the front center of my dash. Quote Link to post Share on other sites
skicrave Posted February 18, 2009 Report Share Posted February 18, 2009 It needs to be outside the cabin. I had a similar install in a past car and any time the view to the south was obstructed for more than just a second it would drop out. Move it to the roof and you'll be set.
