I am sorry for my ignorance, but I need help. I spent a few days trying to update maps on my car pc (windows 7 ultimate). I have been running Garmin MobilePC latest 5.007 or thereabouts. I can't get the newer maps to display. The last update was gmapprom.img back in 2014 or so.

I used gimgunlock to try and unlock a 2.4 gig and a 1.6 gig image. Is anyone running 2016 or 2017 maps on a mobile PC? Please tell me how.
