I had my HU professionally installed along with an after market tailgate handle with a backup camera on my 2010 toyota tundra. During -20 temperature, my tailgate broke when I tried to open the tailgate. I bought the same tailgate handle to replace but the camera no longer works. I only see a yellow Triangle with an exclamation mark. Per a couple topics in the forum, I went into the factory settings and Other tab. I do not see any option to enable a reverse camera, only see an option for forward camera. The canbus is set to 08 - Toyota_camry_rav4 (simple). I've also tried the 42 - toyota_camry_rav4_no radar (simple) but nothing works. What am I missing?
