Most new stereos are 'ISO ready', meaning they have a wiring loom to an ISO connector on the back. Unfortunately my stereo isnt brand new, so I have to find that wiring loom for it.
That was the problem I had origianally. The last stereo was hard wired, making a mess of things, which meant it was a buggar to fit another stereo. my fix was to solder in an ISO socket to make it easier in the future. So I dont want to go back
