Since my first touch pad mod prototype seems to be holding up, I decided to make the mod replicable.
Okay...here are some measurements:
Button spacing:
width = 1 15/16" x height = 1 5/16"
Minimum backing dimensions (w x h): 2 1/2" x 1 5/8"
Maximum backing dimensions (w x h): 3 5/8" x 2"
I went with a backing dimension of 3" x 2". I cut 2 pieces from some scrap Lexan. I'm using 2 pieces so the Tetrax Fix magnetic base will fit. I used a 1/2" hole to fit the magnetic base on my prototype.
Currently working on designing the backing plate to mountable on the factory windshield mount. The mounting plate will have enough space between it and the touchpad mod plate so the cleat will clear the back of the touchpad mod plate. I'll still be mounting mine to the dash instead of the windshield mount though.
