I was curious if anyone knows if the factory back-up camera can be modified to be turned on in a forward gear. I thought that if this can be done it would be a nice feature to have when towing something especially if its small. I just rented a tiller with a small trailer for a garden and all I could see was the handles on the tiller in the rearview mirror because my truck sitting up so high. I can understand gm not installing this feature due to the camera monitor being integrated in the rearview mirror. If anyone has an idea on this please let me know thanks.
