Kenworth smart nav acting up

[Lonestar10]

Mine in my T680 locks up from time to time i just hold power button till it does a power cycle then works fine...theres 2 persay plugs on the radio and 3 antenna connections 1 plug goes from radio portion to touchscreen other plug is huge square with a buncha wires for power and whatever else. could start there the plug comes out by releasing a levered handle that then pushes the plug out of the radio....maybe this handle has come loose and a couple of signal wires are not getting good connection?

or could be the radio is dying. which in my case will be the day i probably replace it with a 7" touch screen radio but not from KW because im guessing the cost of replacing these fancy smancy parts goes deep into the $1000s.
