I'm installing a pioneer avh-x4700bs in my 06 lbz NON BOSE truck. I ordered a metra axxess aswc-1 sterring wheel control in a package deal off amazon. But after doing more research im wondering if i shouldnt have got a pac c2r-gm24?? I found this after doing some research on diesel place forum. But im still confused on the differences? Am i good to go with what i got or should order the pac unit instead? Thanks for any help!
