there is a good company that makes a gazillion kinds of mounts
(blanking on the name) some sold by Aircraft Spruce and Sportys ( get the co. name there)
but check with the company itself.. for many more styles.
I made a mount for my similar sized ( but more capable) Samsun Tab2
using a piece of Plexiglass cut a bit bigger than the tablet.
I bought clip board spring clamps, which are glued to each end of the plastic - this holds the tablet
firmly.
In my situation ( cruisair) a 3rd clip on the back of the plastic panel clips the mount to the aircraft panel
In your situation you may have a horizontal glare shied protrusion to fasten to.. or you may need a goose neck
or suction cup with articulated mount.
I got all my parts including the glue from Tap Plastics.
The commercial mounts have more elegant corner clam mounts, but what I have done doesn't interfere with
the operation of the Garmin Pilot touch pad features ( plus I've got internal gyros and GPS nyah nyah). :lol:
Hope this helps
