Garmin Edge 840 does not connect to Garmin Express

I just received the device today. It synced with the Garmin Connect on my iPhone automatically and asked for software upgrade. Then I wanted to connect it with Garmin Express on my mac, but it won't find the device. I use the latest Garmin Express 7.24.0.0 and Software version 24.55 on the Garmin 840. I have other Garmin Devices connected to this machine OK, i.e. - Edge 830, Forerunner 920XT, Varia Bike Radar, and Garmin nuvi. All devices work OK via USB. Any idea what can be wrong with the 840?

    • Haven’t tried again yet. Anyway, I’d prefer an official fix to a workaround. Laughing

    Thank you so much for this solution. Worked for me. But it is a shame that Apple is not supported. Cheers

    I'm still unable to connect my 840 (25.24) to my Mac (15.1.1) with Express (7.24.0.0). Somehow I was able to connect it originally, maybe I updated something that broke it? Tried the whole MTP / Lap button trick but no difference, maybe I'm doing something wrong but OpenMTP (3.2.25.29) can't see it either.  

    The super annoying thing is that I just want to move all my configurations from my older edge. If the Connect App on iOS could do it I wouldn't be fussing with this. Yes I can use the Garmin Share option for more things than the connect app supports but still not everything I want. 

    Manually migrating is ridiculous in this day and age. I'm not typing out all the locations that are on my old edge by hand in the 840. 

    UPDATE: My old edge 530 (9.75) is no longer able to share with the 840 (25.24) using Garmin Share / Device Transfers and it seems I'm not even able to manually add locations even if I wanted to. Adding a location on the 840 is not intuitive and there isn't a discoverable way to modify it manually anyway.

    I was able to migrate my settings via Garmin Connect app on my iPhone.

    Yes you can migrate some things that way, "Sensors and Activity Profiles" but not courses, segments, locations, workouts among the ones I'm looking to migrate over unless I'm missing something.

    Hi,

    the connection with Express does work now, after I changed the preferences in the Express settings: no hook in both checkboxes (run in the background, automatic start).

    Sorry, i have the german Express Version and have to translate.

    Hope that helps!

    I realized that in order to connect in MTP mode, you need to make sure the device is properly turned off, not just in sleeping mode, because it should start the loader with the lap button pressed. If it was sleeping, the lap button will not help.

    That did the trick and the 840 connected and synced. But Garmin Express completly reset my 840. Everything is gone! I could scream!!!!

    Garmin Express did not just reset my 840, but reverted back to 24.56. I had the 25.24 installed since it was released.
