So I have the new, to me, CLS (350 Grand Edition) and it has Linguatronic. I have done the voice recogntion exercises and this is what's eluding me so far: If I have the map on screen, for instance and I pull the stalk, I only get navi options - Can I pull the stalk and say "radio" or "audio" and get music options instead, or do I have to be in the music screen for that? Does it only understand a limited set of command words or instructions, or does it "understand" as does Apple's Siri, so I can talk to it naturally? If the former, where can I get a list of these commands? Why won't my iphone 4s bluetooth to the car? Or is that a whole different can of worms? Only had it a couple of days so I am sure it will all become clear but all help welcome - thanks!!
