i did the pac with a pioneer around for 650 you can add the mastro i data link to the pac kit. the install is hard for some the camaro dash kit is not the easiest no matter what kit or radio you go with,it is doable harder if you have the gauge pack on the console.i did mine but i was a installer in another lifetime and have done MANY radio upgrades in the past.if you have a few extra bucks i think i would have it done or go for it.
i went with this and am quite happy i also added a back up camera.
