rear camera reverse wire

[jsilerjr]

2009 Silverado......I have a factory navigation radio . I added a gmx550, The 550 has as an option of turning on the rear camera at any time, even if it isn't in reverse, I have found the blue wire in the MBEC , cut it... wired the orange/black wire from the 550 to the harness side wire.. Camera comes on in reverse like it should. when you activate the any time option... the camera comes on for about 10 seconds then turns off. The gmx550 still has control of the screen, its just black... it appears that it has lost 12volt power to the camera... Not sure where to go from here any suggestions. Coastal electronics , where I bought it is no help at all.

Its seams no one knows any more than I do, so lets look at from another view... when the vehicle is in reverse, Is the camera getting 12 volts at that time, or is it getting the video signal at that time, easier said Is the camera powered all the time or is the video signal on all the time, it has to be one or the other cause there's only one wire turning it on and off

thanks

Any help please

well any one who is interested , I finally found the reverse wire for backup camera, everyone was saying it was the blue wire in the x10 connector of the MBEC, which is wrong ..that wire is for the backup lights... keep in mind this truck is a 2009 silverado with factory nave and back up camera....The wire that controls the 12 volts to the camera is a lt green wire in the BCM module located just to the left of the MBEC module. If any one is interested I can post pics of it.. Everything works fine now , I can shift to reverse and the camera comes on , then put it in drive and turn on the camera rolling down the road with the GMX 550, Ive been working on this for 4 weeks now glade to have it working
