2010 Mazda CX-9 with Pioneer avic-z120bt, dvd headrest, amp & capacitor

I need to get better picture with a better camera some of these are very cloudy

Hi all,

I'd like to get some advice or share your experience with replacing the OEM radio in a 2013 CX-9 with Bose system. I've just purchased Metra MZTO-01 adaptor and tried to connect it with my Pioneer AVIC-F50BT unit. The only result is that when I turn on the ACC or ignition, loud interrupted beep sound comes out from speakers.

Could anybody please give me advice on what can be wrong? I'd appreciate advice on connections from someone who's using this adaptor or some experience with replacing the OEM radio in 2013 CX-9 with Bose.

Any help will be greatly appreciated. Thanks.
