Head Unit replacment

Hello
I've got a H3 2007 with Monsoon written on the cargo bay subwoofer area.

Does this mean I have a Bose system or not?

I found 2 after market options I think I can use (for Head Unit replacment)

PAC OS2 (none Bose), or PAC OS2Bose (for Bose)

or

GMAH24 (None bose) or GMAH24b (for Bose)

How can I tell which one I should buy?

Many Thanks in advance for your help

however it is considered bose when it comes to aftermarket.

the interface you need is the GMAH24b, and if you would like to keep the chimes (open door, key in ignition, belt) then you also need GMAHCM chime module.
