I have a commander that was working 2 years ago. Just yesterday I plugged it in and the problem I am having is the commander displays the boot screen with the Apexi logo lit but it won't go passed that point. I have unplugged it and replugged it back in and no luck. The only thing I did different was install a J spec RHD harness and changed the blue plug. The car starts and runs fine. I really need this working cause I use to display my settings I have no aftermarket gauges in the car.
