Volvo factory bluetooth add-on - do I need to have Volvo reprogram the stereo?

I have ordered and received Volvo part number 31201104 https://www.volvopartswebstore.com/prod ... 01104.html

This is the actual kit that I ordered from ebay https://www.ebay.com/itm/VOLVO-HANDS-FR ... Be&vxp=mtr

And am wondering if this is all I need to install bluetooth on my XC90. I have seen other addendum parts to this kit mentioned (mute option, etc) but no real direction on what is needed and in what circumstance. I have the PREMIUM (not the High Performance) sound system.

Also, once I have this kit installed, do I need to have VOLVO reprogram the stereo?

No, once you get it in, it sits in line from the amp to the speakers.

It's unlikely anyone would know for sure. My '06 S60 has it installed, but it was in the car when I bought it.

On mine, wiring wise, it is effectively placed between the radio/external amp (if equipped) and the speakers. When inactive the BT module bypasses itself via internal relays so that the entertainment system powers the speakers directly. When active/talking the audio system is disconnected from the speakers (literally) while the BT module uses it's own internal amplifier.
Motorola customized these for a couple different OEs with vehicle specific wiring harnesses to make them plug and play without cutting any wires. There was also a consumer version, model# IHF1000, that could be wired to virtually any car either with vehicle specific harnesses sold by Motorola or by cut/splicing wires.

By design it's a pretty universal device. I found a pdf manual for the generic IHF1000 version because I was having trouble figuring out the voice commands to clear everything (phonebook, paired devices etc) from the PO. The 'mute option' appears to be when using it standalone with a separate speaker/not wired to the factory speakers. In that case you need to run a wire to the 'cell mute' trigger on the back of the radio.
