Im looking to install a Pioneer nav into a 2015 mazda 6, non-Bose and have a few quick questions...

I have the metra harness, however Im being told that the new mazdas require a more in-depth harness to work. The kit in question is the Best Kits BKMAZK855X

Do I need this kit or will the standard metra harness and aswc-1 get the job done. I dont mind buying the Best Kit if I need it, but to the tune of $20, Id like to make sure first.

Much appreciated
