Has anyone had success finding a serial port on an OEM in-dash
navigation system?  In my case it is in a Dodge and I have found that
the manufacturer is Alpine.  I haven't had an opportunity to take it
out to see if it has a serial connector on the back.  I doubt that I
will get that lucky, but maybe there are serial pinouts somewhere
inside the unit.  Has anyone explored this?
