The local car stereo expert told me you can´t change the radio on a 2015 Expedition. I looked at the Crutchfield website and called Crutchfield. They told me that the factory stereo includes climate control tech, and there is no space, so it is not possible to upgrade the stereo with anything other than the factory radio. This seems really bizzare. I have a fabulous Alpine stereo I put in the 2009 Expedition-it is also part of the back up camera system. Why on earth would Ford prevent customers from upgrading the stereo? Is this really true?
