What's up everyone.

Got my first benz yesterday, 2011 C300 but it didn't come with navigation. Got a really good deal on it, so passed up on navigation.

I found the flip out screen and navigation unit on ebay (~$900 for both). Plus I can sell non-nav unit I have now with the screen for ~$400. So it's worth doing.

To install it in my car, will I just drop it in where non-nav unit is? Is there any extra wiring I need to run or do reprogramming?

Thanks

i would recommend to go to the dealer for the install because you'll need more then just the unit and screen + the dealer will add the NTG4 to your car card

Taking it to the dealership will cost me a ton. Trying to do it myself.

Taking it to the dealer - or someone who knows how to install and code the device - and who has the necessary equipment is sound advice. It won't work otherwise and will be a wasted investment. Advice from members who've "been there, done that".

So, it's not easy to do and you can really mess up the electrical system in the car....

But if you still need to do it, you would need the screen and comand module. You will also need a gps antenna and new wiring harnesses, which is fiber optic and brittle, I think, don't quote me. You also need a module that makes the screen open and close when the car is started and shut off, respectively. So really I am sure a couple wiring harnesses are needed.

Then you would also need to program the module as well as telling the car you have navi. I'm a little foggy on how this is but it's there...

If you can get all the parts, find someone who is familiar with the Mercedes system to help you install it. Otherwise, you should avoid it since it is not simple plug and play like your BMW.

Hope this helps and all the luck to you.

Yea, not gonna mess with it then. Taking it to a dealership will probably cost $3000-$4000+++

Guess Iphone maps will work for now.

Thanks everyone

i did the retrofit from APS50 to NTG4!
got the NTG4 module and screen from ebay for 600$ went to my dealer and he bought the rest (cooling duct, one extra cable to power the rotor and a new center air vent wit the rotor control buttons), did the install and added the option officially to my car.
costed me an other 500$ so in total 1100$

That's not bad.

NTG4 is the main block right?

yes for the pre facelift models it is the NTG4 COMAND and for facelift models its the NTG4.5 COMAND
