Question for double din kenwood - retain sirius radio + BT?

[FlashEngineer]

Hi, I have a 2010 Mazda 3 GT, comes with the BT integration already with the steering controls and sirius radio.

So I bought a Kenwood double din unit, DNX570HD - says has sirius and BT integration.

What do I need to do to use the BT integration that is factory on the mazda with the unit and also how do I hook up the sirius radio to the head unit?

Ok so I found out can't do BT. But does factory sirius unit, is it separate or integrated into the main unit?
