incomplete 'see map' link to google maps

Hi,
I have location and gmap working together OK. There's a problem with the 'See Map' link that should link to the google map for this location. The location info is correct and the gmap appears in the gmap block with a marker for the location, but the link to google maps is incomplete and links as follows:

Location
United Kingdom
52° 21' 8.0532" N, 1° 14' 37.986" W
See map: Google Maps >> links to http://maps.google.co.uk/?q=,+,+,+uk

I can't give street addresses for the locations I want to mark. They'll all be marked with Lat and Long only. And all will be UK locations.

(see http://screencast.com/t/U5ncOjkojk) Please let me know if there's more information you need from me.

Cheers!
