Yes, Once the device is fully active you can switch it between vehicles as you desire.
Yes the OBD unit can be installed in less then 30 seconds.
The devices use the cellular networks to transmit data back to our servers. All the location are obtained using a minimum of 4 satellites . This unit is currently only offered on the AT&T network.
By default the devices do not make any noise. All devices have dim LEDs. You can cover them if needed and it will not impact service.
Every passenger vehicle manufactured since 1996 has an OBD port. Heavy duty trucks manufactured after 2000 are compatible and will have one of two ports. 6 pin J1708 or 9 pin J1962. You will need an adapter or the HD Y cable.
