I have a GTN 650 and GTX 345 but the screen size is too small on the 650 to read anything on the map. I wish I had a 750 but the 650 was installed before I bought the plane.
A Mooney friend has the older Apollo MX20 (Garmin bought Apollo and replaced it with GMX200) in his plane connected to his GNS 430 and it works great. The MX20/GMX200 is a large screen.
Im considering purchasing a used GMX 200 and installing I’m my 201 for map and traffic, or I could subscribe and get charts for the GMX 200. The unit is not supported by Garmin anymore but since it’s only acting as a display I’m not so concerned given the lower cost. Used GMX 200’s sell for $2k -$4k plus install.
I use an iPad Mini with ForeFlight connected to my 345, but would prefer to have a panel mounted sunlight readable large screen that doesn’t freeze or get too hot.
Anyone have any wisdom to share on this thought?
