Garmin GTN750 - VNAV not working?
I have a GTN 750 / 650 setup in my 2001 C182T with steam gauges. Since getting my instrument rating, I've noticed that I only am offered LNAV on RNAV GPS approaches when the Jepp charts clearly show that VNAV is available. I called Garmin about this and they said to check the SBAS settings to make sure that WAAS/EGNOS was enabled and it is.
Is there something that I'm doing wrong or a setting that I don't have enabled? Or am I missing some equipment that would enable this?
Thanks
