As already mentioned in other reviews this is the OS Landranger 1:50 scale map of the entire UK on a micro SD memory card. If you are not sure this is the right map for you or your activities then it might be worth checking the differences between a Landranger map and an Explorer map. Essentially Landranger has less detail and has differences in the map legend on how things are displayed and the colours used. Not hugely different but enough to warrant some learning.
I use mine in a Garmin Oregon 450 and it is pretty much the perfect combination without any issues on a technical level. Anyone who blames the map for not doing what they expect are either not reading the map properly or they simply have the wrong type of map for their chosen activity. This micro SD card is the same as having the 204 paper maps you would need for complete UK coverage which if you got for a fiver each would amount to £1,020 !
I use mine for walking and plan the walks using Garmin`s free download PC software "Basecamp". Once you plug your GPS in to your PC you can view either the OS Landranger map or the street map. From there you can create tracks and routes on screen, alter, add or delete waypoints, zoom in out, plus many other functions in 2D / 3D or both. From the PC you can upload your route to your GPS and see the route superimposed over the Landranger map complete with all waypoints. Generally it makes sense to compare the route created on a paper version of the more detailed Explorer map before setting off and to ensure accuracy. Again though this may be activity specific. It works for me.
Before I had this setup I used Explorer maps with a compass and planned routes before leaving home. These items still come with me as a back up and reference if required but in practice the Oregon and Landranger combo do not miss a beat. It is incredibly useful and accurate enough for walking / hiking assuming you have entered accurate data. Yes... good data in good data out and you will not be lost!
There is not really anything bad to say about the actual map, it is exactly the same as the paper version from what I can see, so if you are not used to or familiar with the Landranger series then a useful tip is to download the Landranger legend chart from the OS site and keep it with you as a reference.
The map itself according to Garmin cannot be updated. From a technical point of view this is probably not true so it's probably a limitation of the OS licence. However things should be very accurate for many years to come so it is hardly an issue. The micro SD card it comes on cannot be copied but according to Garmin you can back the files up to your PC and re-copy them to the original SD card. Not sure what good that is if your card becomes damaged, worth doing though if you are the type to accidentally format your data.... The map can also only be licensed to one unit.
Personally I think the backing up issue needs to be addressed at some point or some kind of replacement scheme put in place for genuine owners. The micro card comes in a larger normal size SD holder and contrary to a previous review this is just a holding case for the micro card rather than being another copy of the map ( my version anyway! ) Also consider that OS have placed a printing restriction on the map so you cannot print any portion of the map.
All in all if your activity is covered by the Landranger map and your GPS supports the running of the map then there is much to commend it. For me now walks are guided with the GPS/LR map almost exclusively and rarely if ever do I need to resort to the paper Explorer maps. I consider it to be excellent value if initially it seemed expensive, and it with the Oregon has transformed the way I plan walks. I guess the ultimate mapping would be Explorer 1:25 which is available for certain areas at huge cost so maybe not in this lifetime!! This however is the next best thing and although I did have a few reservations before purchase as I was so used to Explorer maps all of those have now subsided after finding out how good this was with my GPS
Very highly recommended.
