I removed the standard headunit from my Coupe this evening as I will be buying a new one tomorrow and fitting it at work. After I removed it I thought "balls, could have made a vid showing how its done"..
It was way to dark to put it back so I just made a clip with the headunit and cage already removed from the car.. It shows how to use the tool and the "grip and pull" method I used when it was on the car ( as pushing the tool outwards is a pain as the HU is well stuck in place )..
Anywayz, hope its of use to someone.
