A FEW THOUGHTS: 1) Many RV radios are selected without SMART tech to reduce phantom load on chassis battery; 2) the old AM/FM/ Cassette has zero battery drain when IGN/ Switch OFF vs Smart Displays that have separate memory power wire, and power loss (battery Switch) loses all programming* of channels, phone, etc.; 3) Many Cameras are powered from Rear RUNNING LIGHTS, so then VIDEO SIGNAL detected by radio/ monitor and then auto switches to video (camera). My (user installed) wireless video RECEIVER also powered by IGN ON, so no receiver drain if ACC ON just listening to radio w/ engine OFF. 4) Radio brand/ model often displays on the screen when tuned ON on smart radios. (* 3-minutes or 30-minutes to program?)
