I too am bewildered by this random ding-a-ling warning when moving off. I had a new 2022 jazz hybrid and when the mileage reached just short of 6000 miles the random din-a-ling sound came alive. I had decided to upgrade to another new jazz so subsequently the chime did not perplex me any more.
However the replacement Jazz (Advance sport) started ding-a-linging just short of 6000 miles (same as the first Jazz). I figured it was something to do with approaching a service and with the car about to go in for it’s first service I assumed it would have some sort of reset and the sound would go away. But to my surprise the ding-a-ling has popped up a week after the service.
I can find no definitive answer for this sound so I emailed the service department and this is the reply: “I can confirm that the chime you are hearing is the GPS Navigation system in your vehicle re-connecting. This can happen when the car has been left standing for long periods or when you are in an area where the signal to the GPS has dropped out. In these situations, the GPS will automatically try to re-connect itself and once connected, the chime is played. This is not something that can be turned off or volume adjusted unfortunately.”
My polite opinion on that reply is that it is incorrect because it ignores many of the details I gave to the service department such as why two cars at approximately the same mileage had the same thing happen, and if it is GPS related why did the sounds not start from day one.
Anyway I got to thinking (I am like a dog with a bone) and wondered that perhaps it is somehow GPS related, but just not how the dealership explained it, and I checked the navigation for updates and the installed Garmin version was a 2021 version (car was new in 2023). So I ran the update and the Garmin version is now the latest 2024 one and I am now waiting to see what happens. If the warning stays away can I assume it is navigation update related? Who knows.
The owners manual has zero reference to it, it appears the dealers do not know the answer, and the internet also draws a blank. It is weird for sure. There is one consistent thing with this noise and it happens randomly and when moving off after powering up the car.
Incidentally updating the Garmin navigation in itself is a little tricky but finding the website and instructions is less easy. I got it figured out though and if anyone wants some guidance I am happy to help
So there we have it. I will give an update after a month or so.
