if you cover the #18 pin on the fuse for the top with scotch tape it will allow you to lower the top while moving. You just need to engage the 3-brake at least one click so that the e-brake light appears on you dash. Total cost $0
but the product you've listed is cool too, I think it allows for one touch lowering of the top while the car is moving. if its parked you have to hold the button.
nice but not worth that kind of dough.
p.s. did I tell you I just spent $100 on sivler hood crest?
