IF both are Factory Units:
DO NOT attempt this, as the BCM (body control module) can be damaged.
The GM Factory Radios are Class 2 DATA Type Radios & are turned on via the BCM
Just because the Plugs look the same, does not mean the wiring is the same, which it is not
Not to mention GM Dealer has to Program the other Radio to your 2014 & likely will not be able to because of the change in DATA
