Hi john,
Your radio off the top of my head is recessed into your dash at the top. as you face the radio you will see four small holes, two on each side. you need to go to halfords and ask for audio keys they are u shaped and cost about £4.00. You will also require a blanking plate at a cost of about £16 also at halfords.
use them to open the radio and release it from the car. un plug the radio.
1) now remove the orginal radio.
2) add the face plate or blanking plate
3) now add the new cd metal cage
4) plug the new cd into the car's plugs (don't worry about the connection as they will only go one way). Also don't forget to plug in the ariel. check now everything is working before you push everything in.
5) now slide the new cd player into hole, you should hear a click and your radio should work now.
Have fun.
