I’ve come across some fake websites which appear high up on google search results when you look for the appropriate term. The websites have a chat option which is operated by the scammers. They will try to get remote access to your computer.
The fake websites (and phone numbers) are:
https://garminupdatenow.online (+44 29-2188-5555)
https://tomtomgopre.online (+44 29-2188-5555)
https://navmanupdate.online/ +61 251040000
https://navman-gpsupdate.online/ (+61 0251040000)
http://navmanupdates.com/ ( +61 1800-144-723)
I've uploaded those phone numbers to bobrtc.tel, so happy calling!
