Just installed my own D3 with the XM module. Everything works great...but since I did both the GPS and XM antenna placement (behind the Instrument cluster on top of a metal bar), I am kind of worry about signal strength. I checked the GPS signals through system info and that seems to be working fine with 6-7 gps icons on orange, but I have yet to find a page to check the XM satellite signal strength. Any pointers? thanks

I have the Pioneer GEX-P920XM and AVIC-D3 and I do not get any strength indications on my HU. It is either "On-Air" or not. I mounted my antenna on the back of the roof of my truck. If your XM is playing you should be OK. You might have dropouts if you are traveling in a northerly direction and your roof is in the way. HTH

thanks for the reply. I actually found a page under NAVI menu/traffic/XM status that tells me whether the signal is "strong", "very strong" , etc.
