I have decided to upgrade the Stereo in my 2012 Mazda 3 Sedan (No Bose, 6 Speaker). I found the PAC AOEM-MAZ2 which is an inline Line out convertor. My big question... When I unplug the Stereo to install this adapter, will it make me enter a security code? My friend that was a certified installer said it probably will but I see no mention of it on these forums.
