In order to make accurate GPS map, MFM needs good quality tracklogs. 1-second interval tracklogs taken by sources below are most welcomed:
- Garmin Nuvi's hidden tracklog feature. Activated either using the easter egg method or firmware patch method
- Any tracklog from Papago-based PNDs with tracklog converted to GPX using MFM's Papago Tracklog Converter
- Garmin hand-held devices such as 60CSx and 76CSx
- PDAs using GPSProxy
- Symbian mobile phones using Sports Tracker or Racechrono
- Datalogging devices
