I want to monitor my voltage while driving so I have two choices right now. Hook up my old Beltronics RX45 or whatver it is (has a volmeter built in) or use the OBC unlock method. I'd prefer to use the OBC, but I don't want to have to unlock it every time I get in the car. Before I get my lazy butt off the couch and try it myself... will it stay on every time I start the car, or will I have to unlock it every time?

Thanks.
