Mercedes E Class 2014 Comand Sat Nav Destination Accuracy

[icedchetty]

After 5 excellent Mondeo's I decided to bite the bullet and upgrade to a 14 reg E class (which boasts loads of upgrades) which I am very happy with except for the dire inaccuracy of the sat nav destination. (Not having folding rear sits is also a pain in the arse but I am getting over this).

The sat nav seems to pick the closest junction to the destination as the actual destination. It does this regardless of whether the actual destination is 200m down the road or 3 miles away on the same road, where ever the closest junction is where it shall land me. The rest of the sat nav function is brilliant and I have no quarms.

Firstly, I am wondering if this is just a setting which I cannot find how to change but after looking on other forums there appears to be a lot of people unhappy with the Comand unit, but no one seems to have mentioned this particular issue.

I am having to carry my 10 year old Garmin wide screen sat nav around with me (which is truly an excellent piece of kit) to complete the final leg of my journey - how pathetic!

Can anyone shed any light?

Thanks Mat

As a starting point, recognise that software on Mercedes cars isn’t that great: whether gearbox, safety aids, infotainments, it tends to be buggy, slow and doesn’t perform the function(s) required that well. COMAND, whilst convenient does tend to lag behind other SatNav products.

However, you should be able to get better accuracy than you are. Are you sure that you’re going through the menus to put in house number etc. rather than just the area?

Also - look at MercedesMe. There’s a great feature that allows you to send a destination from your smartphone into COMAND (once it’s up and running, discard the rest of MercedesMe... it’s unreliable and, if you have the adapter module installed is prone to running down the battery).


Still... back in 2007 Mercedes GB’s best advice for the lack of full postcode functionality (was limited to 5 characters in the postcode) on COMAND was to “use a separate Tom Tom system” .... on a £70k car ????!!!!

The Satnav in my 2014 E class is no less accurate in finding destinations than my stand-alone Garmin.
Obviously if I only use the postcode then it only gets me to the vicinity of the actual address I am looking for. The more rural the destination then the larger area is covered by the postcode.
If I add in a house number with a postcode then it takes me to the door.

Likewise if I use a road name and and a number then it is spot on.

How are you inputting the address you are looking for?


Don’t get me started on the turn right / left instructions which I swear are sometimes said incorrectly.

I have the Mercedes Me adapter installed in my 2014 car but I cannot find the way to send a destination from my phone, I thought this was only possible on the later cars. Interested to hear if it is possible on my car.

2014 should have COMAND Online I would've thought? That is the better system.

Also what are you using to input your destinations? Generally doing it via POI will get you a more accurate and precise result

Based on the responses I think I may be a little further along in understanding what might be going on.

I have only ever used just a postcode for destinations on any sat nav device. My 10 year old top spec Garmin appears to take me to the center - or close to of the postcode. After checking out the postcode boundaries in a few scenarios, it would appear that the Comand sat nav takes me to the edge of the postcode - and in rural situations as mentioned in responses a postcode covers a larger area than urban - hence the Comand taking me some 3 miles difference to what the Garmin takes me when just entering in the same postcode.

I am still however skeptical that this may be adjustable with Comand as the when I reach the destination, the voice always states "the junction is the destination".

The worst scenario I have been in was when I was looking for Loch Tay in Scotland and the Comand arrived me just short of 9 miles of the destination.

I will certainly give Mercedes Me a whirl when I get a chance, thanks for the prompt.

I'm glad you have said this, I'm sure I've had this happen too !
