I can believe that - anything over 10,000lbs GVWR is a truck. Will be interesting to see what it does when I head west on I-10 soon - speed limit 80! That is also the truck limit in west Texas.

Hey Shadow.. I think you will find the limit icon will indicate the truck speed limit for whichever state you are traveling through. If the speed limit in TX is 80MPH with no designator for trucks, you should see 80 in the limit icon. Please pass along your finding.

Back with an update for this thread. When driving in Texas, my 2019 chassis is never showing higher than 65MPH on the speed limit assist regardless of the road speed limit. This includes on interstates posted at 80MPH. As best I can tell from some Googling, the heavy truck speed limit in Texas is 75MPH. So it appears not to be working correctly here. It’s as if the database through which the speed limit signs are filtered is not correct.

I noticed the same thing in east Texas. It never showed me 75.

I've noticed something odd about the displayed posted speed limit too. On I66 west of DC it never shows the 70mph limit as the highway is in the more rural areas, it never shows more than 65mph. This is in VA, so I was also thinking it must have something to do with either truck limits or a programmed top limit in the MB software, then as I drove south into NC, GA, AL and FL it would display 70 whenever the signs showed that speed. Last night I was coming back into VA on I95 and there is an area south of Richmond with the posted speed is 70 and that's what was displayed on the Sprinter's display. So that mystery continues.

I'd also like to comment on this earlier post on the cruise control issues,

"Picked up a new 2020 Unity 24MB on the 2019 Chassis with all the safety bells and whistles. Drove it about 250 miles home so we had time to play with it. Had the same problem with my wife but not me. I weigh about 220lbs and she weighs about 115lbs. She is not heavy enough to keep the cruise control activated. Would pop off with error message "Active Distance Assist Canceled" after about 5 seconds to 5 minutes. She must be just almost heavy enough to keep it activated.
Called MB Customer Service and got the "cant adjust a safety device explanation." Talked to my local dealer and he promised to investigate and respond if he learns anything. "

I would definitely call BS on the answers you got. The seat sensor is a major part of the safety system in any new car and the weight of the occupant of the seat determines how the air bags deploy and the seat belt works in case of an accident. If they're telling you that your wife's weight is not enough to use the cruise control I would certainly want to make sure it is enough to trigger all the other safety features that are installed. Tell them that you are going to make an inquiry with the NTSB (I think they are responsible for vehicle safety, if not do a google search), to make sure the feds are aware of this possible safety deficiency. The cost of replying to one of those should light a fire under their butts. At least it would force them to actually post the lower weight limits of this feature. Good Luck

In a little late on this post but had a similar issue. Picked up 2020 24mb on 16 Oct. and drove 250 miles home. Cruise worked fine for me but would either not set for wife or fault out promptly after she had it set.
Did some research and found there is a seat occupancy sensor in the drivers seat that will not allow cruise to work if seat is not occupied. I weight almost twice what my wife weighs so we figured that was the issue. By spec talking with service it requires 65 lbs to be activated. wife weighs far more that 65lbs so we figured it was because LTV reupholsters seats with their fabric.

Solution was (not a good one by the way ) to take a seat cushion (bow hunting tree stand cushion ) and add 25 lbs of lead shotgun shot and place on drivers seat when she was driving.
Bingo! it worked.

We left for AZ. on 20 Oct from Iowa and about 1500 miles into the trip whe tried it without the weighted seat cushion. Walah it was fine. I assume the upholstery relaxed enough so the tension was not supporting the majority of my wifes weight.

Hope yours is as simple as mine
