geographic data of nodes, shown in a google map.

Hello,

I'm building my website in drupal.

Each node I create will have it's geographic data (polylines and markers) and I want to view them in a map.

I tried some modules with no luck. I tried Gmap+Gmap_addons and an attached .KML with it's goegraphic data in each node, but I had 2 problems:

1- I always get a popup with the message "gmap-auto1map-gmap0" beafore a map loads.
2- I can't aoutozoom to the content. I have to specify the bounds in the macro.

I also tried with Geo module, and I write directly the polyline's coordinates in a field of the node that then should load a map; but I get nothing.

I found modules for markers, but I also need a polyline in every node.

Now my question, is there a solution for what I want? Any hint?
