What are TYP files?
Imagine a map where all roads look identical, just black lines, and all share the same width.
You would have no idea if you were on a Motorway , a footpath, a railway line or even a stream!
To solve this problem, Garmin came up with a system of types, all starting with 0 x [a number] for highways, 'areas' and points of interest. Tracks are 0x16 ,Buildings 0 x 13, Car Parks 0 x 5, telephones 0 x 5100 etc
So now we can not only distinguish between highways of different types & widths but also different spaces and POIs.
Even Garmin 'soon' realised that their maps looked extremely dull and oddly, did not show all the types.
To make maps appear more detailed and colourful the TYP format was introduced - see typ file format.
TYP files have had various stages of development - the earliest TYP files contained no label text.
With the introduction of Car/Motor Bike Sat Navs Garmin added Extra Pois.
The latest versions allow for Active Routing.
Where can I download TYP files?
Please remember that using a 3rd party TYP file may produce unexpected results and may not show all the information embedded in a Garmin Map.
This is because a typ file can only reflect the interest and needs of the person who created it.
Walkers,mountaineers or cyclists highlight different highways and select different POIs .
The number of POIs is huge ; when you use TYPWiz you notice typ files only contain a small selection of all available POIs.
If a POI is not included in a typ file AND not part of the default Garmin set, it will not be rendered.
It may also be that
- the POI is NOT included in the IMG To check this use img2typ.
- only basecamp and not mapsource will render the POI.

Can I edit a TYP file?
Change the default Garmin map without a TYP file
Some IMG files do not come with a TYP file. This is no problem as you can create a matching TYP file:
Img2typ is a GUI that at the click of a button collects all the typ data contained in any Garmin map,locked or unlocked and creates a matching typ file.Use TYTPWiz2 to customize the TYP file.
How do I upload my new TYP file to my Garmin?
One way is to use MapSetToolkit.
A single Typ file is embedded with any number of Garmin img files in a file called gmapsupp.img.
MapsetToolkit enables you to upload your map via Mapsoure or Basecamp without using special scripts.
TYPWiz3 & 4 also come with a tool to upload a TYP to any Mapsource/Basecamp map.
