YOU have a USB port!
YEs, but not on a general-purpose computer. On the TV set. According to
one of the manuals (I forget if it's the user or service manual) you
candownload updated frimware for the main control processor in said TV
and store it on a USB memory device under the right filename. Then plug
that into said socket and select some option from the TV setup menu and
it will re-flash said control processor. I am sure there are various
checked made on the firmware file first... Not having any way to download
things ot a US Bmemeory deviec, I've never tried it.
(My CAR has one (Prius-V))
Odd.. My father's car has a CAN bus port. And yes I have used it.
