Mounts for Garmin handheld GPS
I for a long time struggled to mount a 296 in an R-22. I don't like drilling holes to do so.
I tried RAM and G-Force with various levels of success.
Lo and behold a mustering pilot showed me a cut down perspex clipboard turned upside down and clipped onto the lip of the instrument binnacle, with an auto Garmin GPS mount stuck on the smooth clipboard surface (or undersurface in this case). If need be can add some velcro under the far end (away from clip end) to further secure it to top of instrument binnacle.
This obeys the KISS principle.
Not sure if it would work with A 350, etc.
