Introduction

If you want maps for your Garmin GPSr and don't want to use Topo GB then you could use the FREE ones from OpenStreetMap [http://www.openstreetmap.org/]. The map files offered here are compiled from the mapping data at OpenStreetMap. The license for these maps are FREE, here is some data from the OpenStreetMap site:

"OpenStreetMap creates and provides free geographic data such as street maps to anyone who wants them. The project was started because most maps you think of as free actually have legal or technical restrictions on their use, holding back people from using them in creative, productive, or unexpected ways."

All of map files offered here are based on data from OpenStreetMap and are licensed under the terms of the Creative Commons Attribution Share-Alike 2.0 license. If you use these files please make sure you attribute the OpenStreetMap community by including a link to www.openstreetmap.org [http://www.openstreetmap.org]. If you alter, transform, or build upon this work, you may distribute the resulting work only under the same or similar license to this one. You can find out more about Creative Commons licenses here [http://creativecommons.org/licenses/by-sa/2.0/].

Have more question about the maps and data? Here is a link to the Frequently Asked Questions [FAQ] page on the site: http://wiki.openstreetmap.org/index.php/FAQ

I use them on both my Garmins and have the whole of the UK with or without contour data. The only downside it that they are a work in progress and missing some footpaths/bridleways but for most of the UK the road data is complete and many paths/tracks are included. If you like them then you can help by mapping where you travel and upload your track logs for use by the community to help improve the maps.

The contour data is from The Scottish Mountaineering Club, more details about them can be found here: [http://www.smc.org.uk/ContourMaps.htm]

Instructions

Download the file you are interested in, unzip it, and save the unzipped file as GMAPSUPP.IMG and then upload it to your Garmin [make sure you have sufficient storage space first].

To upload/install one of the above map files to your Garmin GPSr, you can either used Sendmap [available from here http://www.cgpsmapper.com/download/sendmap20.zip ] or if you have a later model which uses MicroSD cards you can either load them directly on the
card, or by using the direct USB Mass Storage mode found in any of the HCX or eqiuvalent models. In this case just place the GMAPSUPP.IMG in the folder named GARMIN.
