Hi MadHatMan,
Apologies for delay in getting back, it worked 100% and within a few seconds I had found the mute line.
More than happy to guide anyone who was in same boat as myself, I can take photos etc, I also got pinout from clarion which people are welcome too. Tried attaching in this reply but can't see an option.
So again MadHatMan - Many Many Thanks you have made me Road Legal which takes a great worry away
Super forum I'm learning lots about my new xtrail so looking forward to contributing as we go.
Regards & Thanks
Martin
