A few weeks ago, the "Messages" area on my G3X started flashing yellow. I touched it and the message "GPS Receiver needs service" popped up. I made a mental note and pressed the "BACK" button to return to the moving map. See attached photo of the message (yes, I know my panel is dusty... apologies ).

This message started popping up periodically. Sometimes, maybe an hour between pops; other times, just a few minutes.

Interestingly, the moving map shows my position perfectly.

Has this happened to anybody else? Any ideas?

Any update to this issue? I have #196 and have started getting this message constantly. I head to Tampa next week for my 25 hour service and was gonna bring it up.

I cant help you with the "GPS Receiver Needs Service" issue, but I can help you with your other issue... "yes, I know my panel is dusty... apologies "
Buy Deionized Water, get a soft cloth damp with it, and wipe the screen. It takes off all the dust that collects on the screen (dust is a magnet to it), but more importantly, it makes your screen not a magnet to dust. It's complex chemistry, not sure why it works, but it does.

Alright, following up on this thread, while having my 25 hour service done Dex replaced the GSA 20 GPS unit. It’s working great now and I haven’t had the message return.
