RAOV VIVA with two phones

Roav VIVA on its way looking forward to it.
I will connect my phone as per instructions and it should work.
Can I connect my wife’s phone to the Roav viva as a second user?
I’m guess I’m asking if the Roav VIVA will register on two phones?
So if I drive the car and car Bluetooth picks up my phone I can use device and/or if my wife drives the car Bluetooth will pick her phone up and the device can be used?
Thank you in anticipation Lee

I am also wondering how the ROAV VIVA Pro will work on two different iphones. I assume that you can get a second phone to work but will the first phone then become nonoperational after you set up the second phone?
