Evening Slaves, so I work for a company that has just installed Telematics in the vehicles and in their own words, they have installed an 'active speaker' for communicating when we are being bad slaves.
Is there a way to determine whether this speaker is also set up for outgoing and incoming signals?
I don't trust this company and would love to have a cheap option to see on my own, if this thing is also listening to me.

Thanks for any help on this.
