I. Introduction
The Map Converter is one of the functions you can nd in
the Suite: it allows converting a paper or electronic map and
loading it in your navigator.
The MapConverter works on PC.
Which maps can I load on my navigator?
MapConverter allows you converting raster maps from the
.kmz (Google Earth) or .map (Ozi Explorer) formats to the
AvMap proprietary format. To use the converter you need to
have a .kmz or .map le.
The “raster” map will be shown in the background of the
vector street map preloaded in the navigator Raster maps
are just images and cannot provide turn-by-turn navigation,
which is possible only along the streets present in the
preloaded vector map.
Attention:
When creating your custom map, be responsible and only
create a custom map from a map that is in the public domain,
that you hold the copyright in, or that you have permission to
use from the copyright holder. AvMap disclaims any liability
for the custom maps loaded into the navigator by customers.
AvMap disclaims any liability deriving from an improper
use of the device in a way that may cause accidents or
damages to things or persons, due to the inaccuracy of the
data pictured in the custom maps.
and next to that the type of map is indicated in brackets
(TCE / TZC / TCV).
Attention:
Do not load more maps with the same coverage to avoid
overlapping (in that case only one map will be visible)
How many maps can I load on my
navigator?
AvMap navigators read up to 8 maps, included those
preloaded in the SD memory card, independently of the free
space in the memory. Please check how many maps are
already preloaded on your SD to know how many more you
can load at the same time.
Maps preloaded on your navigator are listed in the maps
info page. To access this page
• Press the Menu button,
• Scroll the pages and press of system info,
• Press the Maps button.
Each map has a name and a map code like this: T-EU-
Qxxx.xx (or T-NA-Q or T-SA-Q according to the continent)

II. How to obtain an image of a map
• If have a paper map is printed, you can scan it at an
appropriate resolution, and save the image as a JPEG.
• if your map is electronic, such as a PDF, you need to convert
it using a suitable program to save it as a JPEG.
The image of the map has to be in JPEG, PNG, TIFF, BMP
or GIF format.
Attention:
the maps have to meet some requirements
• The map should be geographic or in Mercator projection
• The map should not have any rotation
III. How to geo-reference the map on Google Earth
Once you have the image of the map (in JPEG, PNG, TIFF, BMP or GIF format) you can geo-reference it, and create the
.kmz le using with Google Earth.
You can download Google Earth, for free from http://www.google.com/intl/it/earth/index.html.
1. Open Google Earth.
2. Locate in Google Earth the approximate place represented in your map. It can be useful to search for the name of a
street shown in the map, to get a reference point. The closer the viewing area is to the location and coverage of your JPEG,
the easier it will be to georeference.
If the map you started from was already
georeferenced, the operation will be easier: it is
enough to get the Lat Lon coordinates of the 4
corners and insert them on Google Earth.
3. Click on “Add” on the Google Earth menu
and choose the option “Image Overlay” (or click
on the “Add overlay” icon on the bar on top of
the map)
4. In the “New Image Overlay” dialog box,
provide a name for the map le and use the
“Browse” button to select the map image on
your PC.
