Does anyone have experience adding a digital rearview mirror utilizing the existing backup camera? I found a 1500 with pretty much everything I want except the digital rearview (tech package). Its obviously not a deal-breaker but I had one on my RV I just sold and its actually quite nice to see a full view of everything behind you right in the mirror all the time. Does anyone know if the rearview camera can be left on all the time on half of a 12" Uconnect screen? I know that can't be done on my current Jeep with a much smaller screen. Thanks.
