Ideally, I'd like engine sensor (i.e. RPM, battery
voltage) info as well as atmospheric info
(inside/outside temperature) and the GPS info on
screen concurrently. Since the monitor would be used
for the overlay info only while under way (not for
video viewing), why not put as much useful info on it
as possible? The microcontroller is capable of
displaying all of the functions concurrently, it's
only limitation is the amount of text it can display,
not the quantity of inputs. Even if I separated the
functions into separate black boxes, I would still
need to build the circuits to interface to the
sensors.

Here is a better example of what I am looking for:

I can use my TV tuner to switch between broadcast TV,
DVD/PS-2, VHS and rearview camera inputs as needed and
can patch in the overlay unit to cover each or all of
the inputs on either monitor.

Thanks,
