How to create free maps for your Garmin GPS unit

I've put together a number of different pages on this topic, which covers how to take data from OpenStreetMap and turn it into a Garmin file which you can load into your GPS unit. If you've never done this before, I'd suggest working your way through them in order.

Tutorials & guides

  1. Basic step-by-step guide to map creation - A newbie guide
  2. Guide to mkgmap style files - How to customise styles
  3. Guide to TYP files - What they are, how to edit them and use them in mkgmap
  4. Advanced guide to splitter
  5. Walk through my compilation process step-by-step
  6. How to improve OSM data using mkgmap output

I wrote these pages to try to help newcomers to mkgmap, because whilst there's a lot of information for it, it's not particularly well organised. Please please please send any suggestions or comments to help me improve things.
