Can someone please tell at what speed will some features of the navigational system become inoperative? It says in the manual that some functions will not work at a certain speed but it does not say what that certain speed is. Please can someone find out or tell me?

Does anyone know the answer to this question?

I have not had time to check this out...it might be a safety feature so one does not spend too much time watching the screen while moving?

As far as I have seen, everything on the comand/nav works at any speed. Is this stated in the US manual somewhere?

blessed

It is a US manual and this is a quote from the manual page 146 under Control systems command navigation(introduction)

Input restrictions

The input restrictions are imposed starting
at a particular vehicle speed. The restrictions
are canceled as soon as the speed
drops below a certain value.

When the restriction is active, certain operations
or entries are not possible.

You will notice this by the fact that some
menu items cannot be selected or certain
operations will not be possible.

If this is the case I hope that the speed is not set to low. To me it makes a navigation system almost useless when in motion if I have to pull over or stop to use key functions like new destination or closets whatever. I know it is an safety issue, but the 550 has voice recognition and you don't have to take your eyes of the road to use the navi plus if you have a passenger they should be able to do the navigating. Almost all cars with navigation systems limit your use while driving so it is not unusual. The only one that does not is Acura and I have not heard of any problems with safety or Acura being sued because someone's attention was diverted while using a Navi.

///MB

Hmm, interesting. Again, as far as I have seen, it seems like I am able to input and do everything while moving.

Also, BMW does not have any restrictions, just FYI. =)

Has anyone ran into these input restrictions?

///MB what a collection of cars.

When I was at the MB dealer awhile back, I wanted to know if MB had restricted any of there nav systems as that was a major drawback and he told me MB does not restrict its vehicles while in motion. Cars that I have used with that restriction were annoying to say the least. Their is nothing more annoying than forgetting to set the nav, having to pull off on the side of the highway for 10 mins while you program the damn thing, not to mention is probably more dangerious as your a sitting target.

Now I don't doubt that might be in the manual, and since S550 has not been delivered yet I can not test it, but I sure hope they did not do that. My current vehicle has no such restriction and I love it!.

rstone you must have an Acura they have on of if not the best Navigation system out there.

Input of a destination via the map is not allowed while moving. I am not sure of the speed though. You ill notice that the option to enter detination via map is inactive while moving. Not sure of any others.

The Acura system is actually the Alpine Navigation system that was modified for Acura. I definately think MB could learn alot from systems such as Acura. I would like to see more mfg's integrate nav traffic into their units. After all, how many of us often travel to places we have not been. Nav traffic is alot more useful as it gives you graphical updates on your map of traffic conditions. I am tempted to try to integrate the Alpine system in the S550, since I perfer XM, and would like nav traffic.

Alpine’s VPA-B211A VehicleHub Interface Adapter can connect your factory video screen to iPod, Satellite Radio, Navigation, or even 5.1 multi-channel music from DVD. And the best part is you don’t need to alter the factory functionality. The only problem is I don't think they have they interface for the S550 yet.

I had a Lexus and most of the nav features were not available while driving. They all are available on my MB, however, I have yet to search for a restaurant at 150mph. Got some experimenting to do.

silberrosa if you have voice recognition can you use your voice to input destination while moving

Mr Rogers

Blessed - I'll answer on silberrosa'a behalf (I'm sure he won't mind). Yes, you can input a nav destination via voice control while moving - very easily in fact.

Address book entries are restricted while driving.

Can Drive 55

Are you saying the address book in your 2007 is restricted while driving? There are no restrictions on any system, and I have all of them, on my 2005 E class.

i7iceguy

Address book is restricted for adding new entries. Sorry I did not clarify this.
