Have a 2020. I did install the RPG prerunner bumper and awaiting the bracket from RPG because they sent the one for 17/18’. I mounted the radar in front of the grill but it still didn’t work, gave ACC errors in the dash. No big deal at the time and disabled ACC in the advanced menu. Was pretty darn east to find in the menu while I was driving. Regular cruise control work fine like normal cruise. Now cruise control doesn’t work at all. Push the button and nothing. I looked in the manual for the fuse location, checked and looks good. I removed the module from the front of the grill. I figured the radar unit would stop Adaptive and Collision avoidance but stopping cruise control completely, seriously what a joke. My GEN1 cruise control never has failed. I am starting to wonder if this new tech is going to be a nightmare.
