Hi all !
New member here, I just finished my install of the new AVIC-Z140BH in my 2009 Silverado.
At the beginning of the week I had installed an Alpine INA-W910, not at all liking the features, I swapped it out for the AVIC with a ND-BC5 backup camera.
I installed the camera in a OEM tailgate handle bezel (part # 22755304, the old GM number was 25958228).
I will try to post pics and answer any questions.
