Garmin Radar power source on 34 MS Trawler

In the process of buying a 2009 MS 34 Trawler, which I believe was delivered with a now obsolete Garmin 720s GPS Chartplotter, and Garmin Radar (GMR 18HD??). Current owner knows little about the boat. During survey we were unable to get the radar to work, or even have the Chartplotter show any available selections or screens for radar. I understand that supposedly the radar options are "Plug and Play" via an RG45 cable to the chartplotter, so perhaps the radar wasn't even powered, even though I had the RG45 cable plugged into the chartplotter.

Does anyone know "which breaker or switch" powers the factory radar unit?
