I've got a Gtech Pro (the older one, but still uses the newer GTech RR/PASS software). Used, but like new, in box, with all original accessories and in good working condition. I know the unit works but I can't get it to pick up the ignition signal on my Prelude (hence I am selling it). I am not sure if it will work on an S2k or not (have not had a chance to try it). Given that I have heard of people using it, I would think it would work fine.

I can provide the buyer with multiple versions of the software and flash/ROM.

Asking $220, will ship included in that price. Compare to the GTech RR at $270+ shipping (most places), you get that functionality for $50 less and no shipping/tax.
