So here's my malfunction: I installed my D3 myself with BT and Sirius and it has worked perfect for about 6 months, then the Sirius started acting up. My D3 shows the Sirius as "Aquiring Signal", I have terribly intermittent reception (seems to occassionally work for 15-20 seconds while vehicle is not moving but even that is intermittent). I have tried a new antenna, I have checked for loose or cut cables and have found none. I have bypassed the BT unit and that did not work either. Anybody have any ideas? Could it be a short in the D3 or Sirius unit? Maybe a cable problem? HELP! Maybe HiFiSi could work some magic? Thanks for any help.

It's your Sirius Box. Mine did that. But it was doing it right out of the box. Not 6 months later. I went through 3 units before I got one that worked.
