I am trying to add a gps to my revolution. When I measure the voltages from the revolution main port, it seems that they are about 0.78 volts. Shouldn't it be 5 volts,or thereabout? Did I break something?

Here is the MainPort/FlexiPort pinout

Voltage (pin 2) from MainPort comes from source you use to power the board usually a Esc/Bec or UBec.
Seems you measure the voltage from pin3 or pin4 connected to the CPU.

Without external power applied to the board you do not have voltage into the pin2.

I did not have my battery connected. All is OK now.

However, I am trying to find the pathplanner input. Where is it.
Now that my gps is working, I would like to be able to enter a lat/long and have it go there.
