I am a bit surprised you can only show one map at a time, but I have an etrex and their capabilities may vary. I could simply be that both maps you are trying to show are non-transparent. While OSM has its own map compiler I have always used cgpsmapper ( www.cgpsmapper.com) which uses an input format known as the 'Polish' or mp format. Anyway, technically you can use GPSMapEdit to extract the map data from the SMC file into 'Polish format' and there are some older programs on the OSM site on how to transform the OSM format into the Polish format as well. You can then simply provide a combined input file for both raw data formats and recompile the data into a single map. There is also a program called gmaptool (difficult to find: http://www.anpo.republika.pl/download.html#gmaptool) which has a simple join facility, but it might not work if you are dealing with overlapping maps (the main purpose is to combine non-overlapping maps for use with some of the newer Garmins which only allow a single image to be present).

Are you sure? I use eTrex Vista, which is a cheaper model than 60csx and I use OSM data + separate contours without problems. The order of loading maps is important (when you look at the list of maps on your GPS unit, contours maps should be at the end of the list). And I think certain maps have some sort of transparency setting turned on, and some do not, but I'm not sure. I use contours which were generated with DEM2TOPO tool (I didn't do this myself). Can anyone help with this? I would like to do the same for the south downs area too once I've worked out how to do this? I'm not hugely familiar with the more technical aspects of this, and am working on windows. I am pretty computer literate though.

Re: [OSM-talk] Garmin maps with SRTM countours and OSM data?
I've tried this, and had all sorts of problems doing this myself, on my Windows machine. First of all, all the maps have to be in a single gmapsupp.img file, but can still be separate maps within that file, as long as you have combined them before converting to the Garmin format. Combining the SMC Contours with OSM maps produced by mkgmap (the OSM map needed splitting with osmcut.jar which introduces additional problems itself including some roads not appearing) causes problems - as you scroll through the various zoom levels you either get contours or OSM maps, and only at certain zoom levels will you get both. I'm sure spending a lot more time with changing the mkgmap settings would result in getting everything right... However, I've been working with some other guys and we are now planning to take the raw SRTM data and ensuring it's built with the same mkgmap settings as the OSM map, which removes these zooming problems. We are working on producing regular updates of the OSM map for Garmin (with and without contours) from a dedicated website www.mapomatic.net Right now, we are beta testing the non-contour maps with a group of people to make sure the maps work fine on a variety of different Garmin units before we release this publicly and move onto working on the contour version (and then onto some other OSM related projects). Hopefully within the next few weeks / months, we would be able to provide you with a full map of the UK with contours that you could use with your 60CSx, although you are welcome to sign up as a beta tester (I believe Stuart has already contacted you directly offering you this).
