Note: I am from the UK, so if you are from other countries, your kit or the manual could be slightly different.
So I did this over the weekend. It was a very difficult job, but I'm gonna write how I did it for reference. If you have back problems or anything, DO NOT attempt this job. I'm quite fit, and it made my back ache. Access is terrible, I also had a few cuts from the sharp metal radio holder.
Firstly, I got all the tools that I needed. These were:
- Some plastic spudgers from ebay. These are the ones I bought
- Some philips and flathead screwdrivers
- Some kitchen knives (that you eat with, not the sharp ones)
- The UK Parrot MKi9200 Instruction Manual, printed. This isn't very helpful, but it's useful to see how things go together, and how to pair the remote.
- A torch. I just used my phone.
- Some spanners if you disconnect the battery. I didn't bother when I installed it in my new 2003 Opel Agila.
This is what I did
- I disconnected all the cables from the blue box which was simply held under the dashboard with cable ties.
- I removed my Sony radio by sticking the knives in the sides, as I didn't have any removal keys.
- I unplugged the antenna and the ISO adaptor at both ends, and pulled out the radio.
- I then removed the microphone, and threaded it through the A-Pillar to remove it. I then unplugged the screen and removed it through the air vent. I had to remove the glovebox for this.
- I then pulled all the wires through, and then cut the power wires before the inline fuse (I cut the off after though, as one was blown anyway)
- For the power, the black wire is ground, the red wire is permanent live, and the orange wire is ignition live.
- I then took the wires into the house and untangled them.
The job is really hard, as access is terrible. If you have small hands it's useful.
