Remove the back cover of handheld. Using the
back of the handheld as a guide drill 2 1/4" holes
into your dash. Drill a 3rd 5/8" hole in the center
of those holes for the cord and pico connector to
go through. Mount the handheld using the existing
nuts you removed from the back. If your dash is
too thick, you will need to use thread extenders.
