[mkgmap-dev] Code to read locked maps

Thu Jan 27 00:55:59 GMT 2022

Hi,

 >> The source code [1] for GPXSee [2] contains a routine demangle() 
which "unlocks" a locked TRE file.
 >> I was aware that there are tools which can do that but never saw 
open source so far.

The unlock code is on GitHub since 2012 (that's four years before the 
GPXSee project has even started). You can create your own locked maps 
using non-Garmin software since 2008.
