2020 F150 Trailer Blind Spot Monitor Issue
We have a new F150 Lariat with the Max Trailer Tow Package. We tow a 2020 Globetrotter 27' FB, and we use a ProPride hitch.
Note: Because we have a Hensley type, I have not set up the back up assist. I understand it doesn't work all that well with a projection style hitch as the pivot point is not in a fixed position relative to the target sticker.
I have gone through the menus to set up the trailer, answering all the questions about length and width in order for the BLIS system to work. However, when I attach the trailer, I get a warning that the BLIS system is deactivated, and the trailer menu that shows all of the info shows the same.
The dealer is at a loss, and I have found several other F150 forum posts on this issue, but none addressing a fix on a Lariat with our option set. I have not found a way to "activate" the BLIS system when the trailer is attached, and there are no different setup options other than the ones that I have tried.
Is anyone else running into this issue with a 2020? Thank you for the help.
