is it some kind of warning something is wrong?


It just started doing it last night, and then it did it a few times again this morning when I went to the post office. There are no warning lights

Go to the link at the bottom and scroll down to (Doorbell 2) it sounds a lot like that sound

I have figured something out since my last post. It makes the noise every time I start the car up in the garage or if I drive off and come back home it makes the noise when I get close to my house. I still have no idea what is going on but I must have done something to the NAV to make it ding dong every time I am near my house. I guess the answer is someplace inside the NAV manual

 

"Warn when near POI"?

 

POIs or stored memory points can have an "audible warning" associated with them(although I've never tried it-it must be very annoying!).

Perhaps this has been turned on accidentally?

 

You are correct, I did turn it on accidentally and it was anoying to have it ding dong every time I drove near my house.
