2020 Glb 250 software issue
I have a 2020 GLB250, the right headlight module was replaced and adaption was performed via Autel 919, I asked the guy to change the frequency of radio from USA to ROW and F to C, he did as instructed using his autel 919, then a strange thing happened, I can’t change dynamic driving modes anymore, no air conditioning change screen shows and reverse camera not showing, also before I had only English lang in the settings option due to car specific is US, now I have all languages including Arabic
anyone had this problem and solved it
