Please, I unlock the cityxplorer map using Garmin unlocker Alternative v5.31 and it's working everything except the Public Transit alternative. How I read here, I think that I need to unlock also pedestrian features (PID2). Would you explain how I do this ? Which software I'll use ? Can I use GMapTool to do this? I have the cityxplorer map in gmapsupp file. Thank you for any help.
