Look at my post in this forum. Post #15. Make sure to do the step after coding. I have always had to do one retry to get it to show the cdmm speedlock.
This will work. He did the video based on my early post (#15 in this forum) of using bimmercode. People started messaging me crazily about it. Multiple people have done the Auto S/S Memory and Screen Brightness change and they have all said it worked for them.
I know there is Sound settings but there are no setting for the Engine ECU except the Auto S/S. There are no Expert Mode settings. Mine sounds great when first starting and then gets REAL quite after about 60 secs but then mine is totally stock.
I do not know. I would imagine that there is someway in the Expert Mode but I did not look for it. I have my Mirrors Fold/Unfold when Locking/Unlocking so I hear the Mirrors folding and also the visible sign of Locked or Unlocked.
I have played with the screen mirroring which probably would play youtube videos. Tried using a dvd drive via usb to play a movie and that did not work. Did not try any further.
