I feel dumb for not being able to figure this out, but… the red/green guide lines on the backup camera have disappeared for me and I’m not sure how to get them back on. No amount of pressing the leftmost parking assist switch seems to help. They were in when I got the car, but went off after I attempted to use the parallel parking assist feature with that switch.
It's not an easy setting to find... You can only get to it when the reverse camera is showing. Put the car in reverse so the camera shows up, then click the iDrive knob to the left (to get to the left side menu). There should be an option in there for the parking assist lines as well as a couple other picture quality settings (like contrast/brightness)
Ah, thanks! Just when I thought I’d explored every menu. 15min to a solution on here, what a great community.
This took me forever to figure out too. On BMWs the icons are always displayed when the backup camera is up.
