D2 Charlie USB Mass Storage

All of a sudden, my D2 Charlie has stopped connecting to any computer (I've tried 2 Macs and an older PC on Windows 10). The watch will charge via the USB plug, but will not connect to the computer; in hopes of using Garmin Express. I am now on 5.60; and have no problem connecting to Garmin Connect on my iPhone (except when the phone is powered off and the app resets itself). I have tried a hard reset. I have ordered a new cable and confirmed that it works properly with other devices. I can successfully connect other Garmin devices to the computer and use Garmin Express. I have toggled USB mode from Mass Storage to Garmin and back again. For the longest time; it was stuck trying to update an app (was stuck in Connect Mobile with Sending Update); but that appears to have ended. I don't know what else it could be.

MacOS is Catalina 10.15.2; but it doesn't seem to really matter as no computer recognizes that a USB is actually connected; only power draw for charging; no Data connection.

What do your contacts on the watch look like? Maybe there's corrosion?

Hi Chris. I have exactly the same issue. It suddenly stopped to be recognized by any PC or Mac. I checked with several cables and no luck. All other Garmin devices are detected, but not my D2C anymore. What could I do?

I’ve lived with mine like that for almost a year now. With a good connection to a phone and WiFi set up on my device, I haven’t needed to snyc it to a computer. Hope this helps.

Thanks LDSPilot. My problem is that I need new maps. Let's see if Garmin can help.

Maps will update via Connect app and WiFi; if properly set up. As I said, mine hasn’t been able to connect to a computer in almost a year, but all of my maps are up to date and current; as well as my firmware. If you’re trying to go third party though; that would be a different story.

With the D2 Charlie being in the Fenix 5X range, I sincerely doubt that the topo map updates via the Connect app on your phone and WiFi. Can you tell me what you mean by "if properly set up"?

That would indeed be very interesting to know. I'm using Garmin devices since decades and have not found a solution to update the maps without USB connection.
