Mine is a 2012 SLK55 with the same Comand NTG4.5 Generation 1 as yours updated with the latest version of firmware. I just went to my car and checked. My unit is also displaying the same message as yours. The Generation 2 version of the NTG4.5 uses exactly the same Hardware as the Gen1 version. However Mercedes refuse point blank to upgrade my set up to the later version. @Wilhelm Sorban has successfully upgraded his Generation1 Unit to Generation2 by using the latest telematics DVD, Vediamo and Star/DAS. Wilhelm has your browser in your Gen2 version also been discontinued on your unit? If it is still functioning it will provide me with more ammunition to challenge Mercedes.
