2. Can I use my CarHub by bmobile dongle in all my vehicles?

Yes, the CarHub by bmobile dongle easily swaps between vehicles.  Therefore if you were to purchase a new vehicle you can retain your device and service, simply by unplugging the device from the old vehicle and plugging it into the new one.  We recommend that you also update your vehicle information on your mobile app.  However if you own more than one vehicle, to receive optimal service it is recommended that each vehicle should use a designated Car Hub dongle.
