Someone said if your system is a non-Bose one, you probably will not have AC problem when replacing it with an aftermarket unit. I like to upgrade my '12 CX-9 GT non-Bose to a Kenwood double din head unit so I can add a backup camera. Can anyone confirm there won't be a problem or have anyone installed one to their non-Bose CX9 (2011 or 2012) without that problem?
