The Radio Information Board

How do you tell if you have it or not? In the menu, look for "Features", arrow down until you find the numbers...IE 04 05 25 29....those are the features installed.

It's an option, better known as Option 29. If the radio doesnt have Option 29, it doesnt have ProVoice. FYI, from Ma/Com, it's roughly a $700 option.
