Garmin Oregon 400t Maps

Do you own a Garmin Oregon 400t? Are you considering buying one?

Then you need to read on to discover the additional maps you can buy and install to take the Garmin Oregon 400t and view your outdoor adventures in a whole new way!

As standard the Oregon 400t is preloaded with TOPO maps for Europe. The Oregon 400t's Topo map feature contours and elevation, really useful if you are hiking or walking over unfamiliar land. However additonal mapping is available to further enhance your Oregon 400t, though that does depend what, where and how you'd like to use your Oregon 400t.

The additional maps that are available provide rich specific map data for different purposes e.g. City Navigator NT maps which provides street-level road maps, perfect when using the Oregon 400t in a car for navigation or for road cycling. In total there are four different types of maps (pictured right) that can be used within the Oregon 400t. Read on to discover more about them.

All of the maps below come supplied on microSD card within a SD card adaptor, meaning not only will they work with the Oregon 400t, but also other Garmin compatible devices that take a different size SD card too. So for example you could purchase a City Navigator NT street-level map, use it with your Oregon 400t handheld GPS and then use the same map in your Garmin nuvi car sat nav too.

Please note: When using any of the map SD/microSD Cards below they needs to remain in your Garmin Oregon 400t at all times so the map can be read. The map card cannot be copied to either your Oregon 400t, PC or external hard drive. However the map SD card can be used in multiple compatible Garmin devices, but only one at a time. Further help with installing and loading Garmin SD/microSD cards.


Garmin Oregon 400t TOPO Maps

Topographical maps or TOPO maps (for short) range are the premium map series from Garmin for exploring and navigating the great outdoors and countryside of Great Britain, France, Spain, Germany, Italy, TransAlpine and Austria and Switzerland to name a few of the available Garmin TOPO map titles. As well as hiking/walking, the Garmin topographic map series are also perfect for mountain biking, skiing, etc and provide high-detailed scale maps of around 1:50K to 1:25K scale.

The latest Garmin TOPO map series uses the best in available maps for each country. For example, Great Britain TOPO maps use Ordnance Survey (OS) data at a scale of either 1:50K or 1:25K, while the French TOPO map titles use IGN data at a scale of 1:25K.

For walking/hiking in Great Britain, Garmin Oregon 400t owners have two options:

1. Garmin TOPO Great Britain PRO 1:25K SD/microSD card (pictured right)
2. Garmin TOPO Great Britain PRO 1:50K SD/microSD card

All Garmin TOPO maps come supplied on plug-and-play SD/microSD card.

Garmin Oregon 400t GB Discoverer Maps

Garmin Great Britain (GB) Discoverer map series has been discontinued by Garmin and replaced by the Garmin TOPO series (see above section of maps). The Garmin GB Discoverer map series comprised of more than 60 GB Discoverer map titles. Each map title covered a specific National Park or National Trail in Great Britain e.g. Yorkshire Wolds Way at a scale of 1:25K.

In comparison the new Garmin TOPO GB map at a scale of 1:25K now features the whole of Great Britain, negating the need to buy multiple map SD/microSD cards. However, if you only planned to visit one single National Park or National Trail you could save a lot of money, by just buying the area you require e.g. North Yorkshire Moors, rather than buying the map for the whole country.

While the majority of Garmin GB Discoverer titles are now sold out, we do have limited number of maps available to buy from ActiveGPS. Currently available 1:25K scale GB Discoverer maps that you can buy from ActiveGPS include: 1:25K Loch Lomond and the Trossachs, 1:25K Northumberland,1:25K Central Highlands and 1:25K Peddars Way and Norfolk Coast Path (pictured right).

All Garmin GB Discoverer maps come supplied on plug-and-play SD/microSD card. View the full range of compatible Garmin Oregon 400t GB Discoverer maps


Garmin Oregon 400t City Navigator NT Maps

If you are seeking street-level road maps for your Garmin Oregon 400t for driving, road cycling, etc, then look no further than the Garmin City Navigator NT map series. Garmin City Navigator maps feature street-level detail for a specific country or region e.g. UK and Ireland, Spain and Portugal, Full Europe (UK, Eastern and Western Europe) (pictured right) and North America (USA, Canada and Mexico).

Garmin City Navigator maps come supplied on pre-programmed SD/microSD card and are not locked to single use within the Garmin Oregon 400t. So if you also have a Garmin car sat nav and wish to use the road maps in your compatible Garmin sat nav device you can do so, just not at the same time.

Also available is the Garmin Oregon 400t Vehicle Mount Kit. The Oregon 400t vehicle mount kit includes windscreen mount and vehicle power cable and is perfect for in-car use.
