H3T Backup Camera

I have an H3T with the backup camera where the image is viewed in the rear view mirror when the shifter is in reverse. I installed the slant back bed cover manufactured for Hummer by Snugtop. The inside rear view mirror is totally obstructed by the bed cap and it would be nice to keep the camera view on at all times. Does anyone know how to over ride the system so that the camera could stay on full time?[/b][/font]

Thanks -
