Greg::
When I was a design engineer for a company in California known as SBE, we 
entered the "CB" business, to our regret, and shortly thereafter faced 
inevitable bankruptcy.  In an attempt to stay alive, I had designed a 5
inch 
deep, NAV/COM that fit into a 3 1/8' instrument cutout.  We already had
all 
the parts for manufacture, we were the leading designer of PLL circuitry 
with proprietary chips in the inventory, but Management turned me down for
a 
manufacturing bid due to a limited market.  Of course it might have been
due 
to a recent recall of 500,000,  40 channel sideband CB units that had been

inadvertently passed through quality control and placed on the market with

no workable on/off switch, but that's a story for a later date!
Just an illustration why technology is so slow to arrive in Avionics.
