The red output next to the black one should be for Tele-Aid. Assuming your car does not have one, the line should preferably be fitted with a 50 ohm plug. All this can be avoided if the GPS antenna coax was connected directly to the Navi, via the GPS antenna connector (at the left of the trunk, close to the trunk lid spring holder at the car side end). I assume you got a GPS antenna coax cable with the Navi processor wiring harness. This may have a securing clip than needs to be removed. Should be clear how each end can be fitted, one to the navi processor, the other one either to the GPS antenna splitter or directly to the GPS antenna connector.

Thanks for your information, I just install the GPS atnenna Splitter, but still the problem appear which once i switch on the map it didnt locate current location, it just identify that my location in a country beside my country!!!!

Any other setting required to solve this problem?

You may try to reset the unit, set the date etc. but I would assume it should start working after it has been on sufficiently long and in an open sky position (to reach satellites). It may take a long time for the first time.

Other than that I would either check the car Navi processor with another antenna or the car antenna with some other GPS device that accepts an external antenna. I'm afraid you've been at this point now for a while, should be close to working but if it does not, perhaps an expert should look at the GPS parts.

Do i need to take this connector to the trunk direct connect it to the Navi device? I assume this is direct linked to the roof antenna!

What do you think?

Yes, exactly. The Audio 50 APS has the navi processor at the front which is why the GPS cable needs to got to the front. Now with the Comand and the separate navigation processor at the trunk, this GPS cable would have to be connected to the navigation processor at the trunk.

However, you should not need to physically move the whole cable (might be a good idea to track the cable from the front to the rear to be sure you are working with the correct cable, but you should also be able to measure it with a multimeter). There should be a connector at the trunk where the cable from the antenna is connected and then extended from this connector to the front. If you can locate this connector, you should be able to first detach the cable that goes to the front (leave it unused) and put a new one from the navi processor to the same connector your disconnected the Audio 50 APS GPS cable.

My problem is, how to shift that cable to the rear where the device mounted?

I am aware on how to open the dashbord centre and i notice that cable gose to the centre inside with some other cables, but am unable to reach the ways in removing it.

Hope DB can help..

Would always be better to check from the car. Relatively easy to follow the APS50 GPS cable and see if it ends to an antenna in the front or if it actually is wired to the rear. If it is wired to the back, there should be an extension connector at the trunk.

As I know, the Blue Farka coax should connected to the processor, but the other side coax I don’t know where is the right point to connect to? Could you please show in details (that will he highly appreciated) with photos support if possible?

Actually I connected mine, and I guess its not connected to the right point, therefore the GPS on Map not location my current position, its just locate around 90 Miles far from my current place, I assume this problem from the Antenna might not connected well.

Please Advise I need your help.

BTW, i went to the workshop and said if your car no locating the current position, there will be a software (CD) that must install to locate your currrent position, and so far he dont have it, he will call me once he recived it, i will try this one too...

Currently DVD navitaon desk in the drive, the workshop said, there will be a special CD to install to locate your current position as much in some cases the Navigation cannot locate your current location as the GPS antenna as conncted well.

In case i need to check about the way you conncet the GPS antenna to the processor.
