You need to fix it again, the enlarge the mounting holes and
not tighten them up so tight, so when the metal of the radio vs the
plastic
gets cold, the can shrink how much they want to, without putting pressure
on
the faceplate.

Yeah, that's what I tried last time. Trouble is, the screws come through
from the *sides* of the audio panel, meaning that they are necessarily too
small for the job, and the plastic that they must go through is too thin.

Worse, one side (where the screws go through) of the faceplate is completely
gone, after breaking numerous times. I have replaced this entire missing
side by building up successive layers of JB Weld (a 2-part epoxy-like
product that is drillable, sandable, and just about indestructible) and then
carving/cutting it to the proper dimensions with a Dremel tool. It was
painstaking work.

It lasted six months or so, until it got cold. The push-buttons for the
audio panel are slightly smaller than the tip of your index finger, which
means when you push them in turbulence, you tend to jam the plastic
faceplate, too. This, of course, puts stress on those four little side
screws, which is what broke the thing in the first place. Add cold
weather, and *pink!* -- it breaks pretty easily.

It's a dumb design, and Narco (incredibly) wants $200 just for the
faceplate!
