Missing HTS/BTW - TZT12/NAC-2

Furuno TZT12 (1)
Simrad NAC-2
Simrad Precision-9

This issue has been discussed before with a TZT14 and a TZT2BB and I didn't really get an answer from either (actually they conflict, one said to set everything to true, the other seemed to imply setting everything to magnetic). Based on other threads, I'll need some more screenshots (sensor lists, etc.) but I wanted to start this thread now while I had time. All of the attached pictures were taken within the same 10 second period.

I am on the original software that the unit came with - I have found no bugs in the software (until now) and no need for any of the new bells and whistles.

When I "goto" a waypoint now, the HTS and BTW are blank. No setting have been changed. Distance to waypoint and time are correct. The autopilot performs as it should. Radar is oriented in the correctly on the MFD so I assume the bearing NMEA sentence is on the network.

If I'm reading this right, it's"
-Part 1 (micro SD)
-Part 2 (USB)
-Full reset

It says new basemaps will be installed. These are different than the standard raster and vector charts that came with the unit? Is there any way to update those? I can't find them on the Furuno site anymore.
