Hi. Im new here and was looking for an answer and could not find one. So this my problem.
Picked up a bmw f21 2016 m sport with missing headunit. Bought a used headunit and plugged in to check, everything worked fine apart from navigation icon being grey. Unplugged it after and fixed everything back the next day. Most of the options were gone. Have no clue of what has happened.
Any help would be great.
Thanks.
