Mazda 6 2016 with BOSE pre-amp Car radio upgrade to Aftermarket Android Head Unit

Hello everyone,

I have received and installed Ownice K7 C970 (6GB ram 128 storage) on my mazda 6 2016 without any problem at all... Bose amp is back to work in full capacity (11 speakers) because the harness is compatible with my car, I didn't have to cut any cable... the 360 cameras work well.. I will explain everything later with photos. (installation was super easy)

Important ;For all that have 2016 Mazda 6 with bose, If you would like to order one from AliExpress, you should order 2017 model because it equals the 2016 and send the seller a photo of this connector behind the gloves box (that's the most important thing to do and without it, you will face problems and the bose amp won't work at all)

Here are some photos to explain how to connect the head unit to the factory amplifier through only one harness;
1- this is the photo of the main harness
