The W212/W207 version does not have the folding display screen that exists in the W204. NTG4 was then introduced for the W204 C class, which is a cost reduced NTG3 with bluetooth in-built and is also the W212/W207 new E class and E class coupe but requires different map disks. A seperate rotary controller is used to control the NTG3 unit NTG3 was then introduced in the new W221 S and W216 CL vehicles, with an internal hard disk for the map but no Bluetooth phone support in the head unit.

This first appeared with the Model Year 2005 facelift C/CLK (ie from Q2 2004). NTG2 was then introduced for the A/B/C/CLK/ML/R/GL vehicles, the navigation DVD was then in the head unit (with the AGW also). This sytem first appeared in 2002 although it was mid 2003 (MY2004) before it appeared in the S/CL and mid 2004 (MY2005) in the SL. The AGW (amplifier, tuner and diagnostic interface) is also part of this setup and it is a seperate hidden unit in the boot or under the passenger feet in the SLK. The navigation processor was seperate and in the boot (trunk) of the car. NTG1 was the first DVD based system fitted to the W211 E class, the CLS class, the old W220 and W215 S and CL classes, the SL and the SLK. What is NTG1, NTG2, NTG2.5, NTG3, NTG3.5, NTG4 etc
