Hi!

Recently updated to ME3.7 via OTA (Don't know if it will show up here). I haven't updated the map yet. (Some problems with old disk and USB C to USB A adapter. Tested with USB C memory stick, it gets up. But doesn't update) But does anyone have an idea of what needs to be updated / is old here? Which possibly Møller needs to update?

It sounds like your ME3.7 update went through, but the map update is being blocked by the adapter or disk issues. Using a USB-C memory stick directly is a good workaround. Usually, the dealer or Moller can provide guidance on which files are current and help ensure the system recognizes the update properly.
