Hi there EvilSEan.
I have installed my autoleads in my Renault Clio, and can say that I was impressed (After finding they actually DID work).
Most stereo's come with a remote control these days, and I could quite happily navigate using that *Arbeit it being a bit dangerous!*
Yes, my auto leads DID work. One thing you have to check with the stereo, is the MEMORY wire.
Use a multimeter (Or simple 12v bulb) to find out which wire is "Permanently Live" - otherwise you will be on here crying your radio keeps forgetting its presets.
In my Clio it was the RED wire that was perm Live - Which worked fine straight to the radio, but the AutoLeads Harness required the RED and Yellow Wires Swapping round, as they were in the incorrect position.
Other than that I can't really say your lead will be the same, as mine plugged into the RED 15way socket at the back of the clock. Which suprised me, as I thought it would be the small yellow connector from the back of the stereo.
Remember - Follow the INSTRUCTIONS (They are crap) and check the Memory Wire is wired to the Permanent Live from your car.
Oh yeah, and fitting it in with the amount of wires can prove difficult. Try to push the wires and blocks into a space underneath or at the side, they wont all fit benhind the radio.
Best of luck - Keep us posted - JG
