Using GPS Gamma (and indicator)
Sometimes, especially after my car has been sitting for a few days, the USB GPS receiver doesn't get a signal look very quickly, so the GPS-controlled gamma doesn't kick in, and if this occurs at night, I am left with a very bright screen. I am adding a button ("GAMMA") to toggle between Day/Night/GPS. The button works great, but I also want an indicator so I can see the status of the gamma. I added an indicator for "GPSGAMMA" which is supposed to indicate the current state, but nothing shows up.
Any ideas as I couldn't find much documentation on it?
