Hi All

I have a 2018 Acadia Denali with about 14K miles. On a recent trip using the navigation system about halfway to my destination, the display screen suddenly goes blank. About 10 seconds later, a message "MAP LOADING" appears and then the driving map reappears and says "route mapping complete" and then routing continues as if nothing has happened. It appears the navigation system simply rebooted for some unknown (at least to me) reason with the same trip destination info.

I shared this experience with the dealer service rep and he was unaware of any similar issue reports. I'm not sure sure if this is a problem but it's certainly a "head scratcher". It has never happened before nor since this one time (so far).

Anyone else ever experienced this issue?
