Navi disoriented

[whizzard]

Realised that my Navi was not able to get a proper fix on my car's location when I took it out for a drive yesterday.  It kept showing my car in a wrong part of the map.  My traveling direction was also wrong.  Haiz! 

 

Anyone has encountered this problem before?  Issue with the GPS antenna?

 

 

[MarkCWQ]

Which navi you using? Comand? Integrated aftermarket? Or those portable kind? Probably some issue with the antenna.

[whizzard]

I am using Comand Online 4.5

 

It has been working fine all these while then suddenly I saw that I was off-road when I got into the car yesterday!

[MarkCWQ]

Go to the compass screen and check if the system is receiving any satellite signal.

[whizzard]

Yeah, it is.  It even shows my car as moving when I am driving but moving on a different part of the map.  Well, the consolation is at least it still shows that I am in Singapore!

 

Wifey is sending the car to rectify this problem later.

[MarkCWQ]

Comand will definitely show car is moving because the system gets speed and steering wheel info from the ECU. But it still needs the satellite reading to pin point where the car is and heading along which direction.

Start the car and let the System try to find a signal. If not, probably good to go back to workshop for diagnostics.

No, the Mercedes car has no car cam yet ..... this car is mainly used by my wife.  Likely that we will buy the same model as mine (BlackVue DR500GW-HD) though I am tempted to buy a new dual cam for my car and "transfer" my DR500 to my wife's car.

Wife just reported that it was an antenna problem.  Got the antenna replaced and apparently it's now working as usual.

[MarkCWQ]

For loss of signal, that's usually the case.

[whizzard]

Yeah, glad to have this sorted out and dealt with.

I also have this same problem today.
Do we send to C&C to get it fix or Opti Werz can liao?

 

It came back normal again, then gone again, and back on today, so funny.

I noticed the compass not working when the map is disoriented.

Do you have VIM (Video In Motion) installed?

At time it does interfere with the GPS signal.

[hangloose]

I did not have VIM.

So far many days map ok liao, but if go too far to Jurong side, the map go haywire.

How siah?

Your COMAND NTG4.5 came from the factory or was it installed locally?

If it was installed locally go find the installer.

If it came from your factory and if that happened again see one of the site sponsors for your problem i.e Elebest, camber53 or ric ric lo

I also dunno lei bro, I just bought a used Mercedes.

If yours is a CNC car (C or E Class) and bought during the MB 125th Anniversary around late 2011 to early 2012, it's likely to be factory installed COMAND NTG4.5 unit.

 

Other than that, if is fitted locally by one of the 3 site sponsors here, because CNC doesn't know how to retrofit COMAND and probably not allow by MB to retrofit COMAND.

 

The main different between retrofitted local COMAND and factory fitted COMAND is that the factory unit antennae is routed to your roof antennae. Local retrofitted unit has separate antennae will probably sit just below your dash board.

 

IMHO if you have problem again with your COMAND best to see locally camber53 aka Gregory or Elebest - Max.
