This going to be interesting. I had emailed Garmin about the 2 different dates/features of the Feb.2016 package and the April 2016 one. Before I heard back I went ahead and called Garmin and they told me to send my card from Feb. 2016 back to get it updated so I did. In the meantime I get this email back from Garmin saying that they update cards 2 times a year once 1st of the year and then again in Aug. and that card dated from Feb.2016 is their most update one. Can not wait to get my "updated card" back to see what heck it is...LOL
footnote: I backed up my Ultra Card to my computer before I sent back. The file dates on them were 3-21-16. So though my package has Feb.2016 date and the features listed on the Feb.2016 package are different from the package with the April 2016 date I perhaps did have the newest version but just in old package. I did not start my unit up with my card in it to check the Version # before I returned it.
