NTG4.5 was fitted to MB cars up to and including 2015, sadly MB usually stop releasing firmware updates shortly after the unit production ends, so I am not expecting any more releases.

Maps are usually released on regular basis for a number of years after the unit is out of production, but then the release frequency starts going down (presumably as demand decreases).

Consequently, NTG4.5 had two maps updates released in 2018, but it seems that the release frequently is now down to once a year.

BTW, NTG4.5 made its first appearance in late 2010 (on MY2011 cars), with maps version 4 (earlier versions weren't released, presumably they were used for internal testing). So between late 2010 and late 2019 - over a period of 9 years - MB released 15 new maps updates for NTG4.5. For anyone with an academic interest in statistics....

how did you get to this info?

From the COMAND screen.... 'Map Version' is the last option in the drop-down menu under NAVI (top left on the screen).
