I have a Z2 and it is bypassed and has the firmware update in it.

I am getting ready to buy the ipod interface and the bluetooth interface too. what do I need to do to it? I know there wasa bluetooth update, but do not know how to do ti.

thanks,

Just buy the CDIB100II and the NDBT1. The bluetooth update was only for Z1s, yours already had it out of the factory
