Large but works as advertised Rated 4 out of 5 stars
Been working great so far. Most testing so far on 220.127.116.11. And a few runs on 18.104.22.168. I see no difference in this add-on vs the stand-alone installation at http://www8.garmin.com/products/communicator/. This add-on is obviously much more convenient to the user since the add-on restart remembers state and such. (The stand alone requires you to close the browser which is lame.) I have run some tests with this version against some of my code that uses the garmin communicator API to access data directly from the garmin unit plugged in. Very cool and easy to use.
(Rated 4 because the file is so big. Seems like that could be smaller since its 3x the size of the stand alone installer... 5 otherwise)
