How do I get Location / GMap / Views setup to display non-US map nodes? Drupal 6, Views 2

I'm using the Location module to store address information for various contacts in nodes. I am then using the Views module along with the GMap sub-module of Location to display these nodes as map markers on a Google Maps style map on a page in my site.

This works perfectly for USA addresses, but I can't get Canada or UK addresses to display on the node map. The link inside the node (from Location module) to view the location in an external Google Map works just fine, so I can confirm the addresses are valid. However, they do not display on my Drupal Views generated Google Map a la Location/GMap.

Note - disabled and/or cleared cache to make sure this wasn't an issue. Also Regenerated marker cache inside of Location configuration to rule that out also.

Is there some kind of configuration setting I'm missing?
I can confirm that it is possible to get locations and GMAP running on Drupal 6 for Canadian addresses.  I have done this on more than one occasion. 

From your description it simply sounds some setting preventing the reverse geocoding of addresses. Edit one of your nodes with canadian addresses and confirm that the Lat and Lon field are empty.  Save then edit again and confirm it is still empty.

If the lat/lon fields are empty try the following 


Make sure you have a valid google maps API key for the URL you are running the site under.
Confirm that the location module has access to this API keys. Reverse geocoding settings for locations module is under /admin/settings/location/geocoding go to Canada and click "Configure parameters"   Or go there directly: /admin/settings/location/geocoding/ca/google  Your Gmap google map api key should be displayed.
Confirm that as a user you have permission to save lat/long info.  Under user permissions (/admin/user/permissions) go to "location module" and check that  "submit latitude/longitude" is selected for users that will be creating the nodes with address information. If not then there will be no reverse geocoding for any address, Canadian or otherwise.
Once you have confirmed the above, revisit a node with a Canadian address.  Edit and hit save. This will re-run the reverse geocoding.  If a lat/long is not saved then I will have to do some more digging. Also if you have lots of nodes in need of reverse geocoding, it is possible to do this programmatically.
Are you using CCK field or location module itself to save the address and lat/on? I am uncertain whether or not reverse geocoding works with the cck location field in D6.
