After taking one more shot, I think the installer actually got it figured out.  The fuse powering the XM module was just loose enough, I guess when you pulled on it, it would shut down the XM module.  So they cut off that fuse block and replaced it with a blade fuse block.  Hasn't happened since.  Those fuse blocks that come with it must be pretty sensitive.

Disclosure: I've never even seen the XM module, so my ideas are just wild guesses. 1st, I'm assuming when you say "radio", you mean the Head Unit (HU). Just want to be sure cause technically the XM tuner (GEX-P920XM ?) is a radio too.
I would think that it is the GEX-P920XM that is causing the HU to crash. It appears that the GEX-P920XM  gets its power from the HU. Maybe a short in either the IP-BUS cable or a connector problem.  Check for bent pins/contacts. Or it is possible that the GEX-P920XM  is the problem. I'd leave it unplugged for a while just to make sure that the HU only crashes when the XM is on. Just to eliminate the possibility that it is a coincidence that it only seems to happen with XM. Do you have anything else chained on the IP_BUS? (HD radio, Sirius).

Are you sure with your new installation there is enough cooling for the HU?

I do mean the Head Unit and no, there are no other add on modudules to test, just the XM Tuner.  The XM Tuner (GEX-P920XM) has been replaced.  I am trying now not to use the XM module to see if it still crashes.  If it was the IP BUS, would it matter if the XM Tuner was still plugged in?  It hasn't ever happend if I select another source.  It happens multiple times per commute with the XM tuner selected.  They have had the unit apart multiple times, so I would hope that they have looked at the pins at least once.  I am not the radio install expert, thus the reason I paid to have mine professionally installed.  So maybe it's time I learned.  Thanks for the comment.

I am sure this is an I.D.10.T question, but I was playing with the upgraded unit and turned on the Eco Graph.  I can't for the life of me figure out how to turn it back off.  I am sure it's very simple, but I must be missing something.  Thanks for helping the helpless!!!

As I recall from my x920bt, it's under Map Views in settings, - where you pick 2D, 3D etc. It's in that menu, for some odd reason.

So it's not a quick on and off button on the screen somewhere?  Seems odd, but I will look for that setting.  Thanks!!!
