GLC Command Nav and Traffic Question
I am a waze addict and have just learned that it is not possible to order the Premium Driver Assistance Package (advanced safety features and distronic) and also get Android Auto.
My question to anyone who owns a GLC is how good is the traffic rerouting on the Command Nav system (this is supported by Sirius Traffic). Would love to hear from any owners!

The rerouting is fine enough, BUT it all depends on how accurate the bad traffic report is in the first place. We compared the GLC's Command Nav/Sirius Traffic condition reporting and rerouting with Apple Maps....same results, and we took the recommended detour while our friends in another car stayed on the original course driving back to Winston-Salem, NC from Wilmington. The end result: We arrived at our street at exactly the same time, so I am not sure that the rerouting was even necessary.
So far the biggest challenge that I find with Command Nav is that the maps get out of date very fast and don't seem to be updated very timely. I have last year's map update (can't wait to get this year's!), and it still does not recognize portions of I-485 outside of Charlotte that has been fully open for like 2 years now! If the nav system doesn't even 'know' new (or 2-years old) highways and roads exist, then the routing is a bit flawed.

Thanks this answer is very helpful. I will probably stick with this SUV as I love everything else about it - I find the seats especially comfortable so even if I have to resort to using my phone for NAV I can make it work.

Not sure where you are located but I'm located in Canada. I tried out the traffic alerts today and it's totally garbage. Told me ramp was closed when it wasn't (might have been closed at night) and roads were clear (green) when there was traffic (should have been red). Stick with your phone if you want more up to date traffic.

in addition there were a couple of times that it took me off the highway to side roads. i got stuck at a light and probably any savings would have been negated
i really wich a message would pop up saying that an alternate route was found and give me the potential time savings and whether i wanted to take it.
truth be told though, even on some roads i travel all the time and no traffic the system sometimes takes me an odd way. i can take the highway or side roads to get to work. both are pretty close in mileage and time. when i get on the highway other nav systems i have used will see that and just leave me on the highway. the comand will keep trying to take me off the highway and reroute, eventually giving up and then switches to the highway route for example showing one minute longer. if it saw me on the highway already why does it try to reroute me to save a minute?
this is my 2nd vehicle with built in nav. my handheld garmin gives better directions than both

I recently traveled from southern MS to northwest AR. When I left, I set up COMAND nav and Waze to compare them. From the outset, COMAND (in Dynamic Traffic Route mode) was showing an arrival time 45min later than Waze, on an 11-hour trip. I set off, following Waze when there was a difference in routes.
I discovered that COMAND's solution to traffic congestion is often to take one completely off of main highways onto smaller, secondary highways. While this makes for an uneventful and relaxing trip, it's also a good bit slower than just gritting one's teeth and enduring a little traffic. I don't want to add the better part of an hour to an already long driving day just to avoid a little slowdown or stop-and-go -- and it was never more than a fairly brief slowdown, even at its worst. At this time, Waze's algorithm definitely handles traffic congestion more efficiently than COMAND's.
I also discovered that the spoken traffic warnings could be a bit long and disorienting, as the names of highway exits often include both highway and street names, coupled with abbreviations that COMAND's synthetic voice would spell out (e.g., "US 49 N/N Spring Street," rather than "US 49 North/North Spring Street").
In the end, I gave up on traffic-based routing in COMAND and went back to Fast Route.

Also noticed that she will give you long winded traffic notifications for are that are not on your route as well as very far away from you. I turned traffic of for a while now I'm giving it another shot but I know I will end up turning it off again.
in the end it is not well executed. This is the first time I used a system with nav traffic I wonder if it's similar in other vehicles with nav traffic or if it's only the MB software

And we won't even talk about her insanely bad English pronounciation when giving traffic alerts...I've mostly given up trying to comprehend what roads or highways she is talking about.

Man, that reminds me---a few years ago I drove from Winston-Salem, NC to Peterborough, ON twice, obviously going through Toronto. COMAND Navi started giving me such a dizzying series of traffic alerts as I got closer to Toronto that you'd think the whole city is stopped at gridlock. As I got to the city and drove through, traffic was thick but flowing quite nicely and I barely ever had to drop below speed limit. I pretty much just use COMAND Nav to set the course, and then I stick with it.
