Sounds like a typical response, designed just to make you go away. I doubt it's true.
I forgot to try it out on my car today. I like ACC though, so don't think I would use the non-adaptive cruise.
From, of all things, the manual;
To Switch ACC to Cruise Control
Press and hold the distance button for one second.
Cruise Mode Selected appears on the multi-information display for two seconds,
and then the mode switches to Cruise.
To switch back to ACC, press and hold the distance button again for one second.
Try hitting the distance button quickly, as in blip, not hold it down for any longer.
The 2013 OM and 2017 video online BOTH say 1.0 second to switch between ACC and regular Cruise.
Sometimes a slight blip is all that's needed.
By the way, I personally don't have ACC so this is not from my own experience.
I tried everything, it really seems like the option is not available. i tried holding for 1 second.. pressing quickly. i spent an hour just clicking theses buttons.. nothing.
I saw a video in youtube, and i did the exact same thing..
I'm really not sure if i can do anything. like a software flashing or something do enable this option.
I owned a dodge car previously, when i update the uconnect display, it also affects the multi-information display, so i though if honda has the same thing, where i can get a software online and update the system i may get this option.
if you guys have any ideas.. please share them, i'm really willing to try anything. even if i ended up removing the radar and the ACC option permanently
