OK, I have a 496, and an air gizmo mount, which I'd like to put on my
panel. I'm curious to the signoffs needed:

The Air gizmo I think should be allowed to be installed by the
owner/pilot as an interior decoration as long as it doesn't involve
drilling or cutting the panel. Correct? If I have to cut the panel
or drill holes, do I need an A&P signature? The W&B change is
negligible I believe.

In order to wire the power into the aircraft power (not through a
cigar lighter plug), I think I need an A&P signature, and all work
has to conform to 43.13, nothing more correct?

How about running extension wires for the XM USB and remote antenna to
the top of the glareshield with the wires behind the panel? I imagine
that needs an A&P sign-off if the wires are tie-wrapped into place?

OK, and the final question: It looks like in order to fit it in, I'll
need to pull the ancient Foster Loran and it's tray out. That's
surely going to need somebody's sign-off. Does that have to be
pulled by an avionics shop (it does have a connection to the
autopilot switch), or can that be done under an A&P's supervision and
signature as well? I figure I'll replace the Loran antenna with a
comm antenna and leave the end available on the panel for my handheld.

There was some FAA decisions a while back concerning the Air Gizmos in
certified aircraft. I did a quick Google search and couldn't find it but I'm
sure someone here will remember the details.

Here's what Air Gizmo's FAQ has to say about it.

Q: Can the Panel Dock be installed in a certified aircraft?
A: The Panel Dock can be installed in a certified aircraft, but you
will need an FAA field approval.
