Hello, have a look at these, I have done what you want to do as I had the same setup in my car.
With the install kit it takes about an hour to change radio over, it is very easy to do. Just take your time and be carefull not to scratch/damage car.
When you remove your ash tray make sure you put a cloth at bottom of console to protect it.
You will have to bypass the amp in the boot, the biggest problem was sorting out the wiring for speakers.
I have made a note of the colour wires and what does what.
I will sort it out and send over.
If you give me your e-mail address I will send you the instructions for the radio install.
The unit I fitted was the VisualX M-650TV/DVD
