I have installed a GRT Sport EX EFIS and interfaced this with my Trutrak Vizion autopilot. The gps is just the GRT internal gps. This all seems to be working fine and makes me want to experiment more. I do not have an approach legal gps navigator. However, if I purchase the GRT ARNIC module and connect it to the EFIS and to the autopilot will the EFIS send vertical and lateral guidance to the autopilot for a Synthetic Approach?
