Hello, I have a Mazda CX-7 2.3 2009 and I bought a radio Teyes cc2plus. I tried to install it in my car but it doesn't work correctly there is no sound and I don't know why. I connect everything I could. Do I need an additionnal harness in ordre to make it work?

 

Does your CX-7 have the Bose system?

Did you buy a plug & play adapter loom?

 

Hello, yes I have the Bose System and it's supposed to be plug and play. The radio came with all the cable needed. What's the loom your talking about? Do you have any link or pictures?

 

Bose system needs extra bits or setup for aftermarket head units. I would contact a car audio shop.

 

I don't know what to do I contact the vendor but he doesn't care about the problem. I try to contact people in other forum to try to get some helps but no solution was found. Only that I should connect the blue wire named amp-con and acc wire. It doesn't work.
