Yeah I did this a couple of years ago, copied the map update onto SD and sold on eBay, good racket $150 a pop then.
Well, good while the goings good - sold to a German WWII nutter who whistle blew to eBay, Holden, and the copyright owner who I had no idea was Sensis, ie Telstra!?
Anyway made reparations and suspended from eBay for a while flagged as an online terrorist, etc.
Do you think a few pirated megs copied onto cheap old SD is worth $50? How much would you pay me for a DropBox link?
Hard to pay anything for software unless it is legit from the source I think.
