GDownloadUrl(tab1, function(html,responseCode) {

GDownloadUrl(tab2, function(html,responseCode) {

This happens before either callback function has run... so content1
and content2 are not defined...
var infoTabs = [
new GInfoWindowTab("Übersicht", content1),
new GInfoWindowTab("Öffnungszeiten", content2)
];
//Erzeugen des Markers mit Icontype als Bild
var marker = createMarker(point,label,icon,infoTabs);
map.addOverlay(marker);
