Maps thinks my car is a thousand miles from home

I purchased my previously owned 2019 Stelvio Q4 from a dealer in Boston and on a recent trip engaged Navigation to return home and the Navigator had my starting point as somewhere in New England even though my actual location was Richmond, VA.
Does anyone know how to reboot or correct this?
Also, I'm told by my dealer that map updates are not complimentary even though the car is still under warranty.
Can anyone advise as to how to avail myself of free map updates?
Thanks in advance for any expertise that may be offered.
