Hi Martin and welcome to our forum,
Thank you also for considering the use of our Google Map - Directions module, where you don't have to use messy Google Keys or Lats and Longs to make things work anymore, whew!
Answering your question to, can I turn off markers? Well, yes you can, but with the current version of Google Maps - Directions from Noxidsoft, you will need to make a programmatic edit to the module package files. If you are keen, see below...
Unzip the package using
7zip or WinZIP or similar and open js/*.js meaning all the javascript files under the js folder.
Find the line of code similar to
| Code: |
var marker = new google.maps.Marker({
|
and delete to the matching/closing brace for that block of code
Now save it and re-zip the files all back into one package and upload it again.
The easier way to do the above is to use a server-side editor for Joomla like
eXtplorer to make the changes.
On your second question, partly, can I restrict a Google map to my own country without adding the country to the end of the search parameter. Yes, see
http://code.google.com/apis/maps/documen.../services.html#Types However, our Google map modules are built with generic parameters in mind so that the module relates to many users, and we just haven't added that parameter yet, but maybe in a future version
Darn, I knew that would bite me in the back-side, I will remove the default addressing in future versions

But, you can do it for now yourself if you are willing to edit the mod_google_map_v3_directions.xml file at line 101, 143 and 144 assuming you have version 2.0.3.
Hope this helps, though lengthy...
