Check this out -

I have an 03 e500 Sport with the sh*tty tape deck.

I had a friend who totaled his car- he lets me take his Command Unit,.

I took the Head Unit and Nav Unit.

Everything was plug and play. My car had the wiring in the rear for
the NAV unit.

Stereo works everything works BUT the NAV.

There is ONE black wire that has an antenna line feel to it.
Its coming from the cars internal wiring in the trunk, it jumps off the
NAV units power and lead wires.

That is the only UNPLUGGED wire in the rear section. However there is
nowhere I can find for it to plug into. There is a similar wire that comes from the
front of the car to the back and then right behind trunk hinge on the driver side
it leads up and appears to route up to my cars snubby antenna.

Is this why my NAV doesnt work? I feels as if its my antenna for NAV?

Any thoughts why my NAV doesnt work?

It worked in the car I took it from right before I took it out.


ps - Also how or what do I need to install XM Sat Radio? Does that jump off my AUX or Can I really Have

CD, CDC, FM, AUX & SAT?? Really is MBZ this effing Awesome?

Did you install the dash and trunk units from your friends car? I think they both will need to be installed together for it to work.

MPOW33R

Yes Im using both his Head Unit and His NAV Unit. And yes you are right they need to BOTH be plugged in for to head unit to work. My AUDIO works fine - But NO NAV.

Any thoughts>?

Do you have the gps splitter? Should be right next to the trunk hinge...1x1 box. One side has two hook ups and other has just one

MPOW33R

I do have a box its on top of the cage that holds the NAV unit
When i run the part # though it says - ECU

Part # of 1x1 Box on cage above Nav unit is
A 025 545 71 3

If its against the wall then i do not have it.

I added the GPS splitter a few min ago, and still nothing .

Screen displays - No Navigation Device ??!?!?!? and the NAV DVD Insert drive has 2 amber lights blinking?

HELPPP??

S2ktony

On the driver rear passenger side did you connect the 2 orange fiber cables to complete the MOST connection? Kinda have to dig in there to find the cables. My Nav did the same thing until I completed the loop. Cables are located under the door sill.

- Driver Rear Passenger side? sorry thats confusing me.

My display says Navigation Device Unavailable

I had all my wires pre existing, my radio and all works.

I have a MOST plug back there already it was just zip tied up with the
other clip and antenna.

Is there ANOTHER MOST plug somewhere that needs to plug in?

So thankful for any help

S2ktony

Haha my bad. On my phone. Thought I deleted the passenger part. I meant to say rear door behind the driver.

- Pull up the door sill
- right under there should be a bunch of wires tied up.
- dig around and find the 2 orange fiber cables that need to be connected to each other to close the MOST loop. That should do it

MPOW33R

Hmm found 1 - still digging - so there should be a total of 2 orange that are un connected -- but looks like I need this connector right?

MPOW33R

Hate to be a pain in the *** I'm @ my car -
I found only 1 open ended Orange fiber cable
I found 2 others that are already connected with a black little box and 1 of them has 1 white dot on the box the other has 2 white dots on the box -

Where does the open ended go? Sorry man really confused

S2ktony

There should be another orange wire. I had a hard time finding it also. Keep digging around

MPOW33R

I got an 03 e500 sport - I lifted out every single wire down to the thick power wires -

Only found 1 orange fiber cable and has a 14 written on it.

Any thoughts?

I had a hard time finding it also. Keep digging around

MPOW33R

I dug and I dug and I dug - nothing

I learned on another site that some cars need to have the MOST rerouted.

Not sure how yet, still working on it
