As far as preparation goes...
Add a circuit to your electrical system for the FLARM.
It's the same connector and wiring as Volkslogger, one end of a CAT5
cable (you likely have one somewhere with a broken latch on the other
end).
If you're buying the "brick" behind the panel version, build a shelf
for the brick that you can mount when the unit finally arrives.
Set-top box you can use heavy duty Velcro on top of the panel, if you
will still be able to see. Look at Darryl's blog for a cardboard
cutout you can fool around with.
