Blue led blinking means the ublox module receive at least one GPS sat with a valid time data.

If I connect with GPS only should I still be able to use the revo's on-board mag for INS13?

EDIT: Found that I had AuxMagSettings Usage set to AuxOnly. Setting to "Both" has returned recognition of on-board mag.

Yes, but it is unlikely that on-board mag will give error-free measurements usually on quads <= 300mm this is hard.
Depends on your flight controller location, if it's far from power lines, and twisted wires can help a bit. Also ESC are switching components and they work like electromagnets.
Usually you can't shield from magnetic field, unless you use 3-4 meters concrete wall, like they do at Large Hydron Colider ;) what you can do best is redirect magnetic field by twisting wires to make it less severe. Any "shielding" around magnetometer is also bad idea, as it may distort static magnetic field and confuse magnetometer.
The best is to have mag on a pole and calibrated outdoors over OPlink far from metallic elements, but you can try of course.

That would appear to be my only option until I can figure out what's wrong with my V9 or get it replaced

Did some testing today and found that raising the FC to 1" off the frame is far enough away from the power wires to give good mag data even under full throttle. GPS Assist with V9 and the revo's mag performed reasonably well in windy conditions this evening.

If using "Both" and aux is not working, then it is the same as using "onboard only"

Is GPS working through the GPS+MCU port?  If not try this:
- use GPS only port and run Revo one time in GPSSettings "autobaudconfigandstore" mode in case the GPS is set wrong somehow.  Then go back to GPS+MCU port at 57600 baud.

No change. I get absolutely nothing from the GPS+MCU port, but the onboard mag seems to be working well, so I have full functionality to experiment with now. It's a ~600mm frame, so I have some wiggle room with placement.

Has it been crashed and that caused this? :(
If it were mine I would look for broken connection between wires coming out GPS+MCU connector and circuit board traces, then I would flash 'next' version of firmware (which has an unrelated fix) using dev uploader tool (./build/uploader_release/OPUploadTool).

It had never even been plugged in and powered on

Well then, what I said before :) , plus contact the seller if that is still reasonable.

I'll try that when I can get a debug tool. Since the Revo's mag is working for me this is low priority right now. I bought it from the OP store and have contacted them with no response.

I have exactly the same problem.
