This has never worked on my 2019 QuickE. I also do not get the on screen phone messages that Giant claimed in the sales literature. Supposedly if you have the dealer update the bike’s software you can activate the navigation, but I’m not sure the messages ever have worked. I would like to update mine but I have a problem paying the dealer to do an update when the app was originally supposed to do it.
This is my one and only complaint after 750 miles of riding. Had Giant not claimed these features, it wouldn't bother me one bit.
