Truth be told, I hated this device. Never worked or very slow to work; however, I do use it 2x to 3x a year for travel purposes. It will not allow me to update. Tells me cannot connect to server. Based on some other threads, I'm confused. Does it have to be connected to Verizon Wireless or can it update via a secure network, such as my home modem? I'm connected to my home secure network and have been able to use it in the past if connected to other secure networks.
