Some hints and tips for others... The googleapi key doesn't seem to have been activated at thier end until 5-6 hours later. I found mention somewhere of this and just retried it and everything works as per instructions...
Those complaining or not on accuracy, you can't use any map for the lat/lon because lat/lon is not unique.. but depends on the spheroid, and datum ... save youself some pain and google geodesic system.
I guess google uses WGS 84 since its integrating satellite data.
The same bugs then seem to reoccur in later releases or you get another irritating bug. I spent a month or so with no batch upload, then uploaded to the latest version and something equally critical just didn't work... its a huge shame because its so close.... it just never works and new features are added in front of stability.. my experience was I had to patch it and upgrade more than any Joomla component just to get help on the forum and then soon as you do its a new problem.. after loosing your data for the n'th time its just tiring.
