I've had a Garmin 800 for a good few years now, and went for the OS Maps option at the time of purchase.
The maps are slightly out of date now, and I was wondering about moving over to OSM instead. I followed the guide at http://wiki.openstreetmap.org/wiki/OSM_Map_On_Garmin/Cycle_map, and got the maps working, although I'm not sure the contours have been included correctly.
I'm struck by how little detail there is on the OSM map for our local area - very few landmarks, ground description etc. Anyone know if it's possible to overlay the OSM maps on the OS Map to get the best of both worlds?
The other thing I stumbled across was https://openmtbmap.org/ - does anyone use these maps, and are they much different from the regular maps? I ride a 50/50 mix of road and MTB.
Cheers!

Have you tried tweaking the settings on your Garmin for what detail is shown at different zoom levels? Obviously it depends on the local area, but I've always found OSM to offer far more detail than you can cope with if you turn all the options on.
I've used maps from here: http://garmin.openstreetmap.nl/
There was also someone on here a year or so ago offering OSM maps with OS-style colours and detail which is what I currently use and have found them very good.
I've got a script on my PC to generate OSM maps for the Garmin using "fresh" OSM data + use an OS style theme. No contours though.
And....anyone can contribute to the OSM data, good to put something back.
Kevin, I use the maps from open mtb, they work well, have contours and enough detail.
Integrate with base camp ans simple to follow.
It's true that there are lots of areas where OSM mapping is crap. You can help by contributing to your locality but it doesn't help if you are heading somewhere unfamiliar (where, let's face it, maps are more useful.
Try this. I put it on my 800 and is really good

It's a bit of a maze this OSM lark!
I'll give that one a shot, thanks Rob - those screenshots look much better.
I've not tried mucking arpund with the settings - I'll give that a shot too.
So is it possible to overlay maps on top of each other? I presume the Garmins don't have enough processing power (or RAM) to run more than one at a time?
I have both OS and OSM on my Garmin Oregon. Not "overlaid" but I can select which I want to see.
You can display 2 maps at once, if one of them is set as transparent. This can work for maps in Garmin vector format. The OS maps are a different (bitmap) format, so not sure if it is possible for those
I usually use the OSM maps from here: http://garmin.openstreetmap.nl/
Plus I have the contour maps from here, as a transparent overlay: http://www.smc.org.uk/downloads/contour-maps
