While I'm not advocating the practice, technically, you can use a tactrix cable and ECU flash (open source software, free) to copy the map while it is on your car. Then you can unmarry the AP and remove it. You'll now have the map to re-flash.
Again, not saying that's the right thing to do, butit's an option. As are some of the quaility free, or low-priced open source maps out there now for your car that don't require an AP.
You'd be giving up some of the other features of the AP, of course....but most people simply flash their cars with it, and forget it.
