184.108.40.206 seems to fix the behavior of the VOR bearing indicator...but a couple other things still seem a little off.
Based on the displays in 2.png vs. 3.png...it seems like the course from the NAV/RAD page is interpreted as the true course not magnetic. I have 128 degrees set as the course in the NAV/RAD page. When the nav system is in magnetic mode (2.png)...the VOR course pointer is pointing towards ~141 degrees magnetic. (This was in the Caribbean, by SXM). When I flip the nav system to true mode (3.png), the VOR course pointer is pointing towards ~128 degrees true. I'm not an expert on the 717...but based on other aircraft I would expect the course in the NAV/RAD page to be the magnetic course?
Second...and I think separate from that...the VOR needle's deviation seems to be wrong. I'm headed directly towards the PJM VOR per the map and bearing pointer (1.png), at 128 degrees. And I have 128 degrees set as the course in the NAV/RAD page. I would expect that the VOR deviation needle would be centered...given that I'm directly on the radial. Instead the center section of the VOR needle is offset (2.png).
Given the mag / true discrepancy above...I also tried putting my true course into the NAV/RAD page (114 degrees). However, even with this, the VOR deviation needle is offset (4.png).
