NEW! Theme Editor 2.0

The most advanced Garmin Theme Editor changing maps on NUVI & ZUMO devices FAST!

  From Garmin:

  'We had wanted to put something together to make it easier to build those themes, but time never allowed for it.  
  I am glad that someone took the initiative.'


Theme Editor is a very popular Editor of Garmin Map Themes (kmtf files) used on many Nuvi & Zumo devices and it's FREE with no junk to untick!

Quickly add new colours to your Maps! New version includes many improvements & a basic Text Editor.

Although not as powerful, map themes are similar to TYP files but lack the ability to edit POIs or create bitmaps and only work with City Navigator Maps.

TYPWiz5.95 can

a) convert themes to TYP files,enabling you to visualise your theme on Basecamp or Mapsource - see below.

b) convert a TYP file to a kmtf file

How to get OSM pois, like speed cameras on your Nuvi or Zumo .

OSM POIS on your Nuvi/Zumo



1) 'Arrow' colours : change 'RTE_ACTIV_LEG'

2)Traffic 'lines' are generated by Garmin and cannot be customised.

To make lines stand out, make your polygons and highways darker.

What it does

All themes have the extension .kmtf / On many Nuvis they are found in a Themes/Maps folder.

Maps contain a maximum of 5 'Presentations' ( categories)

Guidance,Browse,Traffic,Turn Preview, Route Preview and Pedestrian

This means you can have your guidance and traffic maps look differently etc.

Some default map themes have only one Presentation. With Theme Editor you can quickly select and add/remove a presentation.

  Garmin informed us:

  'I think that you can safely ignore all of the presentations but the “Guidance” presentation.  
  Late in development, we decided to change directions and make all presentations of map use
  the same base theme.'


It appears that some lines have a bitmap although they cannot be altered by the user, ie

The notion of such lines having borders is somewhat confusing.

No point changing some Lines and Areas

There are quite a few lines and areas which are never rendered on your Sat Nav, ie contours,power lines,building shades.

This is because no such data is included in the City Navigator Maps.

Small waterways, rivers, always seem to have a default blue.and are not altered by MISC_WATER_LINE


Roundabouts are not affected by a theme . Their size and colour are taken from the type of highway they represent.

Lines where border colors have no effect

Picture left illustrates the difference between Trails and Unpaved Roads

They are normally barely visible on your nuvi but rendered as green and orange. Both have borders in the kmtf file but these are totally ignored!

Beaches are rendered orange as a polygon.
