Having recently bought an eTrex 30 I was keen to get obtain some mapping to use its full potential. The new Garmin GPS units allow you to download 1:25K OS maps at a cost of £20 for a user defined area of 600km2. This is actually a very small area making the Birdseye Mapping extremely expensive. The Birdseye maps are also very poor quality.

The Garmin GB Discoverer maps are 1:50K scale, but I find that this is perfectly adequate for walking with a GPS. The GPS tells you where you are so the level of detail is less important compared with using a paper map and compass. Garmin sell this product for £200 on their website, but it is available for £150 on Amazon making it good value compared with other options.

In my opinion, buying the full GB mapping will make me more likely to use my GPS as I have made a one off investment that I might as well use. The alternative of downloading Birdseye maps at £20 for a small area, would make me think twice about whether I needed the map and I probably wouldn't bother for small walks. For example, if I went to Scotland for a week and planned on doing 4 walks, I would be faced with a bill of £80. GB Discoverer is good value in comparison.

The main downside to the product is the fact that is stored on a micro SD card which can not be backed up on a spare card or PC. I you lose your GPS or wipe the card the data is lost. Personally, I would prefer to be able to store the data on my PC and just transfer the relevant data to the GPS when I need it, but this option is not available.

Overall, I am happy with my purchase.

The Good:

Full GB Mapping for your device on a micro sd card. Also allows use of latest Garmin Basecamp software to view the map on your PC screen when connected to your device. This includes really neat 3d displays, planning etc. Also significantly better on the PC screen than using the Garmin Topo GB V2 mapping (which seriously restricts the viewable area.)

The Bad:

SD Card is locked. You cannot back it up. If the SD card fails or gets damaged you have lost your mapping. (There is a 12 month warranty though.) Map display on my device (Edge 800) is poor especially if you zoom in. The quality of the raster image looks like it has had to be reduced to get it down to a workable size. The map is not as flexible as the Topo V2 GB Mapping that I have on my GPSMap 60csx. Yes there is more information but it's difficult to read. The map is a raster image so if your unit is set to display direction of travel towards the top of the screen then the map text will be upside down. You can use an overlay to get names the right way up but you then get both upside down and right way up text. Believe me if I say it's not great on the Edge 800 Display!! Using Basecamp software you can view but not print any portion of the map.

I daresay the backup restrictions are down to the Ordnance Survey rather than Garmin.

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.

maps received and everything works BUT the maps are several years out of date which has a huge impact in the area I bought it for as there have been some major changes (new road put in along a different route [gen 3 road], old roads removed completely [gen 2 raod], very old unmettled roads [gen 1 road] converted to cycle tracks) - so in most areas it is probably fine but in mine the maps are incorrect from day 1

As I had some issues around the handheld GPS unit I bought the maps for, I did not find this out until it was too late to return the map
