Great work.
is it set up for plug and play, or need to be programmed per vechicle?
so, just have to wait till the display says code sent then start, didn't take ling
how is the brightness on the screen, to dim at day or to bright at night ?
could a simple small green led light be pigtailed to a location of users choosing, when green light comes on, car can start, and leave the monitor under dash, and just pull out if there is a problem?
or a plug in display, if there is a problem , then can plug in and check / diagnose ?

TY for your work.
