I'm a new user of Garmin 1490LMT.
I insert some favorites and now I want to delete them.
After I delete them ( directly from favorites one by one or from My Date by selecting all or a part of them) and after I restart the Garmin all favorites are coming back.

I connect the Garmin to my PC to check if is any file to delete manualy, but I couldn't found anything.

Can you help me?
