I'd like to avoid the GPS splitter
Here is the situation: 2003 E55, already had the bracket for the navigation drive in the trunk, as well as the wires.
I added a euro COMAND, euro DVD navigation drive, and a North America map disc.
I reconfigured the most loop so that the drive is seen, and I now get the maps and destinations in the COMAND, and there is a polite British lady who is telling me that she is calculating the route.
Problem: the GPS signal does not work. I understand that getting a GPS splitter would solve this, but isnt there a way to simply use the existing GPS connection that TeleAid has, and turn off TeleAid since I dont need it or want it? Anyone know how to go about this?

The GPS splitter is the device that splits the GPS antenna signal from the antenna to the navi processor and the Tele-Aid unit. Euro cars that don't have Tele-Aid have a straight-through connector in the place of the splitter. I would assume you have that as long as the car only has Tele-Aid, why not disconnect the Tele-Aid cable and put the navi processor in (and code off Tele-Aid to get rid of malfunction messages).

The main problem is that I dont quite have my head around the way the GPS antenna is connected and routed. There are a few threads that people are typically referred to when adding COMAND and navigation, the GPS splitter is typically mentioned as well.
In my car there was a blue GPS antenna harness hanging together with the MOST and electrical harnesses in one group, and they all plug into the DVD drive. Since TeleAid is there, then shouldn't this harness be coming from an existing splitter? Or is it not connected to anything at the other end, wherever that is?

Its like $80 or something, so if I can get around getting this thing by just swapping some wires, I'd like to do that. On the other hand, since I'm already a few hundred bucks into this project, and there is no way around it, then I'll just get it and finish up.

Did you follow this thread, and this specific post:

You can see the splitter installed. Note that Tele-Aid at this point has only the GPS antenna in common with the navi processor. If you really want to avoid buying the GPS antenna splitter, you should feed the GPS signal directly from the antenna to the navi processor instead of the Tele-Aid unit as it should go now.

I got this figured out after finding an entry in the WIS about retrofiting navigation. So when its pre-wired, there is a bundle of 4 wires hanging for the navigation processor: black, blue, harness, MOST. I knew the blue was for the GPS, but I hadn't realized that the black was the other end of the same wire.
I disconnected the TeleAid's connector from the GPS antenna and connected the nav processor, exactly how I wanted. Now I'll just get TeleAid disabled by STAR diagnostics, and that will make the malfunction warning go away.
