One might extend this conversation to the thousands of PDA's that are
semi-permanent (and unapproved?) additions to glider instrument panels
(yes, I plead guilty as charged).

My understanding is "approval" isn't required for general aviation use,
because PDA's are portable devices (like a handheld radio, GPS, and
oxygen), and the only requirement is the pilot determine they do not
cause interference.

This doesn't mean we can't think of ways to cause ourselves trouble with
some of our mounting methods. I was guilty of mounting a GPS antenna on
the glare shield, which would've affected the canopy jettison. I've
removed the antenna to a better location, and when I mounted my MRX
transponder detector on the glare shield, I used a connector that
releases easily.
