This is the link you need to my old thread
AMI retrofit - Navigation Forum
It's easy, the parts that go in the armrest cost next to nothing and are super easy to install.....I actually did that bit myself but the running of the fibre and power I had someone do for me but again I'm told it's super easy
Post here if you have questions and I'll see what help I can offer.
If you close to Milton Keynes I can put you in touch with the expert who do the fitting for me
