Map Update Warning

[HughA]

Every few days when I start the car I get a very loud warning, a bit like a door bell.  Nothing shows on the display to tell me what it is.  After Googling a few things I believed it to be a notification that a map update is available for the built in Garmin SatNav. However, going through the map update procedure I get a message that my maps are already up to date. So maybe the warning noise I get is for something else.  Does anyone have any ideas as what else it could be and how to disable it?

No messages or icons on the dash ?

Nothing at all unfortunately!

The only notification you should receive regarding Garmin, is a small 'folded map' type icon in the top right of the Garmin page.
This isn't very reliable though, as after going through the palaver of the USB/Garmin website shenanigans it will still sometimes say 'your Garmin is up to date'. Every now and then it will throw a curve ball.. and there will actually be an update.

When exactly do you hear this sound? Might be when you go from P to D passing R rapidly. Maybe a parking sensor could spot something, but time is too short for the display to change?

Totally unlike any other warning sound, a bit like an old fashioned telephone bell and very loud. It usually happens before I even shift out of Park.

Clutching at straws but do you have the fob in a tight trouser pocket

I know if a fob button gets pressed it can produce a sound but I don't remember it being a bell

My solution to that was to ensure my house keys were across the buttons side of the fob in my pocket

It does sound like the map update sound, if you quickly switch to navigation you may see a banner just disappear at the top of the screen.
