Garmin Leslie you are closing all the threads down with GPSmap67 questions as not inReach as far as I can see the issues are exactly the same for the GPSMap67i inreach models with exactly the same issues.
The GPSMap67i inReach model in system settings - usb mode has exactly the same options as the GPSMap67 i.e either MTP or Garmin, I have also tried a GPSMap67i at work and cannot get Basecamp software on a Mac to recognise the device, MTP usb setting on a Mac does not work with Basecamp software on a Mac, will you be adding Garmin Serial to the usb settings on the GPSMap67i that does work with the GPSMap66i and Basecamp for Mac ?
