Hello,

Just installed a pioneer avic 920 bt in my 2007 Mazda CX7 GT w/out nav. I got all the necessary equipment (Mazato, steering wheel controls etc.) and the install went off relatively quickly. However have noticed that there is a buzzing/crackling/humming coming out of the rear 2 pillar speakers now. Anyone have a possible cause for this and hopefully a solution?

Thanks

Recheck all your connections, sounds like you may have a loose or crossed ground.

Will be checking the wires again. Also it seems to be noticeable at low levels but goes away when the volume is increased - not sure if that would provide any further insight.

Thanks
