Is the any way to cancel the twin map veiw?so its a full screen instead of cut in half

you can put the reverse wire on a switch and view it on full screen

if you put the switch in make sure you diode isolate the wire from the car (reverse wire), so the reverse lights aren't on while you are driving forward

cool,where should i splice the switch in?yeah,that twin map is good but it sucks you cant disable it somehow

Subscribing to this. I've been wondering the same thing.

You really dont even need a diode if you use a SPDT switch.

Just wire it like below. If you have backup lights that work off ground instead of 12 volt then you need to wire the switch accordingly.
