They where £1.99 + free P&P they removed the radio with no problems at all
The only problem I had was removing the old cage which was easier than I thought.
I pulled out the bottom tray and managed to pull out the surround which has also the heater controls attached to it.
Behind the surround the cage was attached by 4 Phillips screws which held the cage in place .
Once that was removed I made sure that the radio and Ariel wires where easier accessible I installed the new cage and plugged in the iso adapter which was recycled from the back of the clarion unit and my new radio was up and running with no problems at all
