It's their warranty; manufacturers can and do -- Porsche is one, if I
recall correctly -- forbid use of ANY after market electronics. However, US
manufacturers have in the past not been quite so restrictive. I suspect the
only thing that would make any of our Big Three this sensitive about EMC is
if they had been unable to get their new model to meet the SAE automotive
EMC standards.

This may be reflected in marketing. If versions sold to government agencies
require special wiring I will view that as evidence my conjecture is on

Of course one way to comply with that poorly written (IMO) warranty
restriction is to use military or commercial gear not marketed as "HAM"
