Trailer coupling screen missing in Command
I say this - the factory installed trailer hitch package includes added wiring from the hitch into the ML - taht then gives you that COMAND rear-view camera feature - and also gives you Anti See-Saw stability control when hooked up - and gives you a factory connector up front to hook up a brake controller as well - stuff like that with the factory installed package.
If you check the Window-Sticker/Factory-Spec-Sheet - I think you will find your ML does not have the Factory-Trailer-Hitch package - but rather the trailer hitch was added by a subsequent owner.
A add-on hitch gives you the hitch and trailer wiring - to get the features of the factory trailer package would cost about $1600+ - requires at minimum a added MB harness from the rear up to the front console - pricey - and very labor intensive.
The good news is the a properly installed aftermarket/added hitch has the same towing capacity as the factory hitch package - a added hitch just doesn't same added electronic/connectivity features.
