looking at the picture you posted, your canbus is a RZ-JP06 (little silver box) which is a Raise, you need to connect the stereo to wifi, and do a update on the canbus, it will add more models to the list. Once that is done, follow the instructions that user Which posted here

My unit finally received that canbus update a couple weeks ago through Wi-Fi and I can confirm the Challenger model switches the display to miles after selecting American in the options. Do you know if there's a specific website to download the file from to keep as a backup?

Any updates to this? The seller that sold us our unit have no communication with us. I bought a OBDLink adapter and used alfaobd but was unable to find any options for it., By looking at your picture there it seems we have the same canbus by RAISE, I was thinking of buying a different brand of canbus to try since it seems that Hiworld and the OUDI brand have the options to set the tire pressure to PSI and the speed/mileage to american under Settings, they just wont apply/save with the RAISE canbus it seems.

wife just had this happen to her, I'm going to be replacing the radiator and the radiator support soon, I was able to straighten out the condenser and the transmission cooler enough to avoid replacement, Any other hints are welcome, Thank you for this!!

I've been researching this for a while, I did find in another forum that someone else had the same problem with a different vehicle and the problem was that the canbus unit doesn't save the settings when it's powered off, the user fixed the problem by supplying a constant 12v to the canbus so it would stay powered while the vehicle is off, not sure how that would affect the battery though. It would be nice though if we could just set imperial to the default somehow, maybe alfaobd would let us override the default configuration somehow. If you do find anything let us know.

I'm currently having the same problem with a unit I bought from temu, everything works using the Raise protocol for the canbus but cannot change metric to imperial on the display above the steering wheel. Do you remember how exactly you got your to change to imperial ? There should be a way to make imperial the default mode.
