EQS Hyperscreen, MBUX and Mutimedia

I’ve had an EQS 580 4matic with hyperscreen for 6 weeks. I don’t think I’ve done a few points quite brilliantly, or I haven’t figured out how this works yet: 1. Internet connection via Tethering The whole thing works pretty well when I set up a personal hotspot on my iPhone and Tethering runs over WLAN. Then CarPlay is also working. It’s just a bit awkward that I always have to open the “personal hotspot” page on my iPhone so that it connects. If I don’t use BlueTooth Tethering, CarPlay will not work. It will be paired in every iPhone state. I get the message “no internet”, although online music works. Working with external data volume and only if necessary using WLAN Tethering I also tried. Unfortunately, my car is located in the office on the 2nd floor in a TG. It can’t be connected and will no longer be manufactured independently. ng. 2. Films on the hyperscreen Yes, it works. You can watch file from USB on the hyperscreen. I haven’t found how to change the audio track yet. The only audio format that works with me so far is AAC. Then all movies jerk, except for one in H.264 with 2,000 kbps. You can still set something audio track/subtitles. It can’t be that the MBUX does not know DTS or Dolby. On the other hand, it is already written by Atmos.
