The reason I chose the compact display of the BMV-712, is thay the manual claims it can be set to automatically switch displaying between voltage, current, watts, SOC , etc., without pressing buttons. (manual section 3.11.1). I can "view" the display in the mounted location, but cannot conveniently "reach" the display where I have it mounted in the limited space in my motorhome. I should be able to press the "-" button for 3 seconds to initiate this display-switching when in operation. My firmware version was 4.0 but soon upgraded to 4.01 after installation. Thank you Victron and I eagerly await this well needed function. Jim.
