gns480 vor data & grt
to clarify my earlier question about the gnx480 (cnx80) vor, i quote from the grt horizon I install manual (pdf download from their site):
VOR data from the GPS cannot be displayed on the EFIS. An OBS selection into the GPS cannot be provided by the EFIS. According to page 2-3 of the CNX-80 installation manual, full VOR functionality is available without an external CDI, although this seemed to conflict with the pilots manual. While you can perform the equivalent navigation function of flying on a selected radial to/from a VOR, the CNX80 uses GPS for this guidance. If you want to see actual VOR data, you will need a separate nav head. Rumor has it this may be corrected with the addition of VOR bearing data via a serial output in the future.
i sure would like for this to work.. my current (mental) revision of my panel includes a gns480 and a grt horizon I. [of course, it's only about rev 12 of the panel in my mind since i started building, and i haven't received my fuse yet.]
