Just as an FYI to all the drivers that get one of the baby monitors installed in their truck..
Yes, dispatch will know where you are all of the time.
No, you can't shut off the machine because they took out the on/off toggle switch. It boots up when you start the truck & shuts off 30 min after truck shutdown.
Yes, dispatch will be able to hear everything that is going on in the truck. Even if you are not holding the microphone. While the microphone is the same as the company radio, the push to talk switch is not used.
Yes, dispatch can listen to you without your knowledge if the MDT unit's lid is closed. If it is open, you must "see" that the touchscreen button has changed to "hangup" to know that they are there and not talking.
Did I mention you can't hangup on dispatch at will because the touchscreen is disabled while in motion?
