Be very careful if you have an sds unit as some of these are firmware programmed & can remove the sds with these nav dvd's.
il check tomorrow , i have the 2016 disk in il check to see if the software update it did has left the sds option intact,also seems like the 2016 disk doesnt have 7 digit postcode option at the moment as this is added by a seprate software which isnt updated yet for the 2016 disk . but it loads instantly like an original disk ,whereas the 2015 disk is slower to load ,due i think to the added info for postcode and speed camera option.
its added to the disk image thats taken from a legit disk . but it does seem to cause laggy boot up of the nav disk on the newer units as the laser in them are weaker and some struggle to read them as easy .
the 2016 disk doesn't have 7 digit postcode as of yet as the software used to add it hasen't been updated yet to allow them to be added
you should have the led screen in the mk2 older mk1 had the lcd screen .
