Andy,
Thanks for clarifying this for me! I couldn't find anything on their site about GS on the G5. However, I should have been more specific in my post. The G5, to my knowledge, will not display GS info from anything other than a GNS or GTN series. The Aspen will accept GS input from older equipment, like my KX-155, which makes it work for me. I'm on the fence about just adding a GTN650 and then I could use the G5's. I so still like the Aspen better. But I think I would need to replace the sheet metal on the pilot side of my 1968 M20F to get the Aspen to fit. I wish Garmin, like Apple, wasn't becoming so proprietary in their products. As an example, I have the GDL 52 portable ADSB/Sirius XM/ADHRS receiver. It is amazing but only works with Garmin portables and the Garmin Pilot App. You'd think a more open architecture would sell more products.
