You flip the switch, nothing happens, or you just hear a rapid clicking sound deep in the dashboard. battery drain. A shorted gem will keep your network awake and will drain a brand new battery overnight. Nine out of ten times this is caused by leaking windshield. The water actually drips down onto your gem module. So use the Fitment tool on my website, drop your make model, gear in the comments, and I'll help you diagnose the issue and we'll get you set up with a replacement gem.
