I have had a "Robo Top" and it has severed me well for 3 years there are a few on our (UK) forum that are looking for the one touch option so if you do get hold of a Robo Top give us over the pond a heads up please, as that’s where I got mine from, but was informed that they were no longer making them.
Just seeing if this link works; (just click on photo) it shows my switch in action on my (03) 986 also I've done the relay mod so I can drop it on the move and I don’t have to put the handbrake on. Sweet.
