Bill is a good guy and I hv zero issues with him or products he sells.
Explaining on here a few issues I had was answered by other members. Truthfully, 95% of the issues I had was self inflicted..

I had a camera staying on after signaling. I disabled it as I didn't want it. And most prompted menus on 23 dash from tazer are only half wrote on screen. So it makes it a little difficult to navigate especially being new to both tazer and truck.
My advice is to really take your time and read EVERYTHING in online manual and then read it again. Then print it so you can use it as a guide while setting it up in truck.
Rebooting and sleep cycles are a MUST to properly install settings.. do not open doors..do not hit brakes.. I suggest sitting in seat, follow the procedure and I used my phone for a stop watch for sleep cycles.
Hope this help or if you hv any questions, I will do my best to help as I made a few dumb mistakes that made me want to just Uninstall it all together. Glad I didn't, really like.
