Things that I have done:
- downloaded MAPSOURCE to my PC
- installed maps 2015.3 to pc (I have lifetime map support for my 1690 so I install maps to my pc along with to the 1690)
- built a new gmapsupp.img file on my CF card
- ran gmaptool against new gmapsupp.img file, noticed unlocked in several places
- downloaded gimptools
- run giminlock.exe against new gmapsupp.img file on CF card (looks like program wrote a new gmapsupp.img file)

So is my next step in this process is run JETMOUSE against the newly created gmapsupp.img file?
