Navigation routing loses location


Did you check from the GPS status menu how many satellites the device can detect? If it shows "-", there is an issue with the antenna, if it shows "0" under open sky, there is likely an issue with the GPS antenna.


Could you give an exact reply to the GPS status question instead of saying "it is OK"?


I don't have the satellite option selected so can't answer that question, but the location is always correct when the system does this.
MBUSA is looking into the problem as we speak on a warranty claim. I sent them a number of video clips from several different episodes. We'll see what they say. So far all I get is "...we can't find anything so we're not going to do anything."
I can't say what my next step will be if they still deny that the problem exists, but I can tell you that we'd just finished looking at a '11 E350 Wagon that my wife really liked when MBUSA called to say that they weren't going to do anything. They did later email back to say that Engineering was going to study the problem, but not before she took MB off of the list.

Do you have any videos or photos showing the map at high zoom? Why don't you want to watch after the GPS status? If the navi processor looses a GPS fix randomly for a moment, pretty soon it would loose position accuracy enough to find the car being off road. If GPS fix is lost, the navi unit would need to work with gyros and speed signal etc. and this is mainly intended for areas like tunnels where GPS is not available but there are neither too many crossroads to navigate through.
In any case, good that you got mbusa looking at your car. Please report us once the problem has been found and fixed.

A month ago they replaced the sat-nav processor module within the command and now the entire nav system is freezing up on its own. At least now with even more video of which shows eight satellites and three calls to mBrace documenting that they have a reliable location signal we should be able to get what I wanted them to do on visit number three which is a new Command head unit.
And now for the rant. As an engineer I understand how difficult it can be to troubleshoot intermittent problems but at some point they need to listen to what the customer is saying. There are only three parts and two cables in this equation and after six visits they've only replaced part of one. It's as if they think we're trying to put one over on them, but as my wife says "where is our motive for wanting a perfectly good part replaced unless there is a problem."
I'm still struck on the point that within my family there have been two instances with Audi where they cover all costs for problems out of warranty with one phone call and I'm on visit number seven with the so-called premiere German marquethat is still in warranty.
