Products.Maps, Google map not loading (alternatives, Plone 4)

I have an old Plone 4 site running with Products.Maps ( Service Kompaniet AS avd. Bergen — ServiceKompaniet ) and it gets the 'could not load'. Is there an alternative to enabling billing (I dont want to register it on me) that works with Plone 4.3.2 (any alternative add-on (or can it be iframed or … ) ?

you can use an OpenStreetMap iframe, just customize the template. Or use leaflet in the template. Or an iframe with google maps ($address contains the address of the place, $lat, $lon the latitude and longitude):

  <iframe   width="100%" 
  height="400" 
  frameborder="0" 
  scrolling="no" 
  marginheight="0" 
  style="margin-top: 1em;"
  marginwidth="0"  src="//maps.google.com/maps?q=123,456&hl=es;z=17&amp;output=embed"
  tal:attributes="src string://maps.google.com/maps?q=$address&amp;ll=$lat,$lon&hl=it&amp;z=17&amp;output=embed">
  </iframe>

Thanks
