It mimics the way the power windows work:
short tap on open or close will fully auto-open/close the top (less than .5 second tap), another tap or long press of either open or close will stop the current auto-open/close function. Holding on open or close will manually open or close the top for as long as you hold it.

the only annoying thing is that it needs a switched +12v supply...I just spliced into the stereo's switched +12v (not the +12v switched by the stereo being on, the +12v from the ignition being on).

Arduino nano:$10
transistors, resistor, and 5v regulator:$10 -$15 (had all parts laying around)
Fun/simple Saturday geek-out project:$priceless

very nice! Where do you buy your Arduino boards?

Also the 987 solved this: from 6mph to ~35mph the roof is automatic one touch. Under 6mph and you have to hold the switch.
