Hi

Just downloaded an installation manual for your stereo, is it also capable of showing video on its lcd screen? It would appear if all your sony wiring is intact that you only need to make 2 connections extra and then just check if you need to swap the yellow and red wires over depending on whether the radio switches off when you take the keys out. the first wire to find is the amp switching wire which is a blue and white striped one which is not connected to the iso block with the yellow, red , black, blue and orange wires. Looking at a wiring diagram for the xf stereo you may be lucky and the blue power aerial wire may trigger the amp. worth a try first if not then you will have to cut the blue wire in the middle between both connectors and crimp on a male and female crimp so that you can rejoin later on if need be. Try to use the same as on the blue and white striped lead as it will make the job easier remember to put the same end as on the b/w striped on the lead coming from the back of the stereo and the opppsite end on the wire going to the iso block. Join the b/w stripped to the blue wire that's your amp switch connected.
Next the difficult part if you are using the video function? We need to find the handbrake switch cable. At the moment I am unable to help on this but I am planning to get a dvd player installed next week when my XF comes back from the paint shop. So should be able to give more advice then. It may in your case be as easy as joining the light green wire to a suitable earthing point. Although I can't be 100% sure. However it worked on my Xf when it had a pioneer Avic system fitted. Cool system but just didn't look right in the dash and I wanted to use the HVAC.

Hope this helps a little.
look here for the pin outs in the iso block
