Nav Antenna Cable Help - 07 GL450
I have read so many posts on this topic I'm almost blind!? I understand that the Nav antenna is supposed to be in the compartment under the rear seat on the driver's side, along with the tele-aid gear... I have looked *really well* and have concluded is is not there. The tele-aid antenna with the blue connector is there, and plugged in, and I can find the connection about 12" down that cable where the splitter is supposed to go, but I can't find any other coax cables in this space. There are 2 other coax cables that are already plugged in to the opposite end of the tele-aid unit and the only loose cable in the entire area is a blue-ended connector that is not coax - it is pinned, with what looks like a loop-back attached with regular copper wires... HELP?! I have already installed the Nav drive with DVD, and the blue-ended coax cable for the antenna was there and is plugged in, but I can't find the other end. I know it (Nav) can't see the antenna because when I hit the "MAP" button, I get a blank screen. I can look at my "destination" and see it on a map, but that is coming from the DVD. Was there an alternate location for the other end of the nav antenna on early '07 models produced mid-2006? If I have to go with an aftermarket antenna for OEM Nav install, what are you guys buying? Thanks in advance.

Any GPS antenna with a FAKRA connector should work - something like this http://cgi.ebay.com/GPS-ANTENNA-FAKR...item3363ba79f2
I don't know *anything* about the GL, but every other US Spec MB with teleaide I've looked at has the GPS antenna plugged into a splitter/amp that's connected to both the navigation system and the teleaide system - so you should have to find the "other" end. Do you know if your teleaide is still working? (Have you upgraded it to MBrace?)
I'd look for the engineering mode key sequence for your version of COMAND, and look and see how many satellites the system thinks it's seeing. My 2.0 has a "default" position it shows on the map regardless of the signal. On the NTG2.5 heads it was showing the "last" position it had a valid signal, which was Brussels of all places! :P
