Garmin Colorado 300 Maps

Do you own a Garmin Colorado 300?

Then you need to read on to discover the additional maps you can buy from ActiveGPS and install to take the Garmin Colorado 300 and view your outdoor adventures in a whole new, more detailed way than ever before!

As standard the Garmin Colorado 300 is preloaded with Garmin's basemap. The basemap includes major roads, rivers, lakes, etc. Whilst useful, this information doesn't match up to the additional mapping that is available to use with the Garmin Colorado 300 handheld GPS device.

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 Colorado 300 in a car for navigation or for road cycling. In total there are three different types of maps that can be used within the Garmin Colorado 300. Read on to discover more about them.


Garmin Colorado 300 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. 1:25K Rannoch and Loch Tay, 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 Glyndwr's Way, 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 Colorado 300 GB Discoverer maps


Garmin Colorado 300 City Navigator NT Maps

If you are seeking street-level road maps for your Garmin Colorado 300 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. 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 Colorado 300. 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 Colorado 300 Vehicle Mount Kit. The Colorado 300 vehicle mount kit includes windscreen mount and vehicle power cable and is perfect for in-car use.
