Cant connect to server

Just bought this today. Want to connect to my sons car, as hes a new driver and hes leaving on a road trip tomorrow. Ive tried to set up an account repeatedly and it keeps saying that it cant connect to the server, try again later. If I cant set up an account and get the diagnostic info, whats the point? Frustrated!

Thought this would be great about Hum: GPS Family Locator, v1.9.1628
