Drive app, stock on watch not working. When pressed error code IQ! Is displayed. Has been not working since last update. Please advise.
Don't you use a Connect IQ app that might be in a conflict with the Drive app?
The best would be contacting directly the Support. But if you want to try finding out what might be the reason, connect the watch with the USB cable to a computer, and open the log file in the folder //GARMIN/Apps/Logs/ with Notepad or with another simple text editor. It may offer some clues, but the data won't probably tell you much - that's usually more valuable for the developer. You can post the last block of the log here, but probably you'll have to send it to the Support, in order that they localize the problem.
