I just wanted to give an update on this as I dropped my car into Mercedes. It transpires that there was an outstanding update for the satnav (NTG 7) My satellite view is now working perfectly, and the toggle button is now available in satnav view settings in addition to using your voice. Mercedes had put my car onto their STAR system, which apparently showed that it was missing the update. Whilst it was in the garage, they updated the power steering recall too, so all is well. Thank you to all those who had responded, much appreciated.

 

Thanks for the update.

To help others in the future - could you post the NTG7 software version you are now on please?

And a bonus would be a pic of satellite view on NTG7

 

I don't see anything satellitey, but it sounds like I'm not missing anything
