Just a quick update to my original post ref converting TT Go files to kml format for use in Igo HGV software.

I have now managed to add my own poi icon.....

Here is my guide to assist anyone else who may be struggling to do it...

Convert files to KML format.

To add your own POI set to the Igo HGV....

1: Ensure you have the following folder in the root of the satnav:
bstrucks\content\userdata ( this should have 2 subfolders called poi & usericon )if not create them.

2: Convert Tom Tom poi etc to kml format using ITN ( keep original file name for ease ) eg: Campsites.kml

3: Export this "New" file to the folder userdata\poi on your satnav

4. Using MS Paint open your original POI icon from TomTom,then carry out the following:
For single images, you can open a bitmap using Microsoft paint (part of windows). Then, select the "Image, Stretch/Skew" menu item. Then enter 200 in both the horizontal and vertical boxes and click ok. This will enlarge a picture by a factor of 2. I have found a bmp file of 32x32 is ample to display on the satnav. Save new image as the Original file name ie:: if bmp was called Campsites.bmp keep it as that.....

5: Drop this new Icon into the folder usericon

6: Open the new KML file using Notepad.

7: Copy the text below and change the parts YourPOI to the name of your own POI then change the name of the bmp file to match that of your poi.

<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://earth.google.com/kml/2.1">
<Document><name>YourPOI</name>
<metadata><igoicon><filename>YourPOI.bmp</filename></igoicon></metadata>

EG:
<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://earth.google.com/kml/2.1">
<Document><name>[color="#FF0000"]Campsites[/color]</name>
<metadata><igoicon><filename>[color="#FF0000"]Campsites.bmp[/color]</filename></igoicon></metadata>

8: Save this new kml file and ensure it is in the userdata\poi folder

9: Start up satnav and go to custom search, then scroll to find your new poi set.

Enjoy !!
