I want to use my phone hands free. Do I need the BT-1 or the CD-BTB200

I think because the AVIC-Z2 already comes with a microphone for voice command, the BT-1 is fine. Anyone know for sure though?

thanks,

Slave

I use the BT-1 on my z2

yeah the 200 is for stereos that don't already have a microphone and stuff - and i put my microphone in the very top of my A-pillar.. i

Same place I am planning on putting mine.
