I hope this is useful to someone other than myself. I have a 2012 Tesla Model S, apparently one of the first without the Tech Package. Why? This has been covered elsewhere in detail. If I were ordering another car I'd get the tech package now (my wife's car has it for instance) but at the time I didn't see the value in it since it didn't route around traffic and there was no supercharger network when I committed to my car! Fortunately my car has some of the features which are now in the tech package. OK, if you download this file Dropbox - tsla_na_scs_2015_02_22.ov2 it contains all of the North America superchargers up to and including Shamrock, TX (added 2/21/2015). See the amazing web site Superchargers and select "Changes" and then "North America". If you see any issues please PM me. I will try to update the GPS file periodically. The file is in TomTom OV2 format. I think you can load the file into POI EDITOR (donation sent) and write out another format. For my GPS I started on this page: How can I install or remove third party POIs? Anyway, this came in quite useful on a 1,200 mile mid-winter trip last weekend with my elderly parents. Normally we take my wife's car for road trips now, but this was an exception.
