I had Sirius Radio installed in my Pioneer AVIC X920BT and ever since they installed the unit it seems to spend more time aquiring the signal than playing. I had it in my 2004 Chevy before I put it in my 2007 GMC and in the chev it worked fine rarely losing signal. Any idea's or suggestions?

Where is the antenna located? Could be a bad antenna.

This turned out to be the AXXESS GMOS-100 module after much fighting with the Future Shop over this. They had me send the Pioneer AVIC X920BT in to pioneer twice to have these problems fixed and wanted to charge me for installation. Pioneer reported bacl both times no problem found. The Future Shop still say the problem is with the unit!
