Removing the Car Radio and Installing Aftermarket Model

Model: Smart Smart 451 - Years 2007-2015
Part: Car stereo

Detach the switch panel with the hazard light switch located just below the car radio: from the central hole, you can access a Torx screw that needs to be removed.
Using a plastic trim tool, detach the plastic frame around the central air vents and the car radio itself: then unscrew the 4 Torx screws located at the corners of the car radio.
At this point, you can pull out the car radio by disconnecting the connectors attached to it.
Apply the GPS antenna to the air duct (it will be hidden by the frame) and the microphone to the cover of the indicator stalk.
Then connect the adapter wiring to the original connectors and then to the new car radio; check its operation; apply the adapter frame and insert it into the designated slot, tightening the 4 fixing screws.
Reassemble the frame, the corresponding fixing screw, and finally reattach the switch panel.
