Antenna amp lead 2010 GL
Racking my brains here, and cannot find any help. I even paid for startekinfo for the day, but that is pretty tough to use. I need to find the lead that powers the antenna amplifier as I have used the factory antenna. I have a 2010 GL450. Someone had to run into this.......Please help!

Anyone? Someone had to run into this with a 2010 Gl before.......How did you get the power to the rear antenna amps, and did your headsets still work? I am thinking maybe those antenna amps may have something to do with my wireless headphone not working.

Hi desant89 - Did you ever figure out which lead powered your antenna amp? I am not familiar with the GL antenna amp, but in one of your other posts you show a picture of the connector, was the connector behind your radio or in the rear tailgate door?
The reason why I ask, is that I have a '06 S-Class W220, the antenna amplifier is behind the headliner above the rear window, I have aftermarket radio and currently I have an add-on antenna because I do not know which wire activates the antenna amp. For my car, all of the functions between the stock radio/comand unit are done via the fiber optic MOST cable, there are only 3 wires and the MOST cable behind my factory radio.
For your setup, you may have to probe each wire one by one with a volt meter turning the radio on/off until you find the "turn-on" wire. But worstcase, this may not work either as the amp may just come on when the ignition is on.

I am honestly in total shock that we cannot find a solid answer as to which wire it is. I did read about some other MB vehicles where they powered the black wire to then power the amp. I just thought it would be simple to find someone that knows which wire it is in all of our vehicles.

I feel your pain as some things are not as common as you might think. I did find this .pdf file for a 2004 ML. You may be able to find something common between your GL.

Thanks for that document though. I will pass it on to my installer to see if it is similar.
