I am adding a few more pictures on how to remove your stereo unit. I found it quite easy to remove as i needed to take out the unit so I could place a band expander on the back of the Stereo as I could not receive all radio channels due to the car being imported from japan and the radio only ever picked up one radio channel.
Here is the first part
First you have to remove the air vent as shown in the picture below. Inside the air vent you shall find two clips (bottom of the vent). You have to push these clips down with a screwdriver to release the Stereo unit. When the clips pop out you then have to carefully pull the air vent out. Also the air vent is a little tight.
