My brothers e46 msport cabby has memory seats and that reverse mirror tilt thing... ill be honest with you its only good for reversing round a corner. other than that its absolutely useless i had to reverse it off the drive and i use the mirrors to judge distance from the pillar on my driveway wall and i have to basically lay on the passenger seat because it wont adjust whilst in reverse. how useless and over rated
On my E46 you could deactivate this by putting the mirror switch in the position as if you were going to alter the drivers side mirror.
