Anyone know where this antenna amp power wire would be in a 2010 GL450? I am living this problem right now after replacing head unit, amp, speakers etc.....

The GL's antenna amp is located in the tailgate, below the glass. Remove the interior trim paneling to get to it.

Any chance anyone knows which wire powers the antenna amp in a 2010 GL450? I tried buying StarTek for a day which was a waste of my time and money. I have the adapter connected in my car, but radio reception is horrible which I am sure form the antenna not being powered. Please help if you can... I am attaching a pic of the plug that I think has the wire in it somewhere. Thanks!

Do you have an aftermarket radio? If so, you need to make sure you connect the radio's power antenna output to the vehicle's wiring harness lead for the antenna. Otherwise, the antenna amp gets no power.

desant89

I understand that. I installed a complete system with amps in the vehicle, and found out about the amp in the forum. Problem is, nobody can tell which wire in the harness needs to be powered by my remote wire to get the antenna amp to power up.

Did you use an aftermarket wiring harness connector? If so, it's documentation should indicate. If not, this may help:

Metra does not make a harness for a 2010 GL for some reason so it had to me wired up manually. Not sure about that document, I sure can have my installer check it out, but it is for a much older different vehicle. Last resort is to add an amplified antenna on the inside of my rear window which is not really what I want to do.

As a side note...Would the GPS antenna work in an aftermarket receiver, provided the plugs match up and so on?

desant89

I will have to find out if my factory GPS antenna was used. Mostly all aftermarket head units come with one that can easily be hidden so I would think the supplied antenna is normally used.

megacrazy

Yeah I know...but in this case the plugs actually match up. I guess we'll find out. I don't see any reason why it wouldn't.

desant89

In my SL I know the factory Antenna was used when I had my Kenwood installed. I am sure it will work.

megacrazy

Great! Yeah this unit is a Kenwood as well. They use the same HRS plug as the stock unit.

where did you put your antenna? I have 2 don't know which one to hook up. Which one would you recommend? Also I have a w164 2009 Ml350 the in advance

Per the thread, I went back to using the stock radio antenna when I found the 12V ACC wire that activated the car's stock radio antenna; the result was that the car's OEM antenna was much better than the aftermarket antennas that I was running. If possible, I advise to try to use the stock radio antenna by finding the 12V ACC wire in your ML, however I'm not familiar with the w164 chassis so I wouldn't know where to look.
