Do you know that there is one hidden camera function in your BMW reverse camera?
Yes, that is the Towbar zoom feature!
Having this option turned on through BMW coding will allows you to zoom in your view during parking. Originally, it is meant for driver to zoom in to their tow bar to ensure that the trailer is secured properly.
A secondary useful function will be to zoom in to the car park slot and park your car precisely in a tight parking slot like those old shopping centers with very tight and small parking slots.
To enable such feature, you have to code this:
|HU_NBT||3001||EXBOX||MACRO_TRAILER_COUPLING||aktiv||nicht_aktiv||Enable zoom on rear view camera for trailer hitch|
