this came up on a Ford Forum the other day... might apply to your car too
Many antenna devices contain a small integral amp, so there are TWO methods to provide power to the integral amp depending upon design
1) phantom feed that sends power 5 to 12V back up the very same coax the signal comes down - this is the method most after-market devices use
2) German car manufactures prefer the more costly and pointless separate 12V feed
thus if Merc use method 2) and your device is only designed to use 1) nothing happens if you plug in the Merc GPS wire
The Ford GPS antenna can't be used with budget aftermarket android add-ons
I have the same fun retrofitting the Merc DAB Tuner on a European car -
I could upgrade to the Mercedes antenna that NEVER really function for $800
or
Fit an aftermarket one for $15 that works correctly all the time.
But when you choose to use the phantom feed supply the Merc DAB tuner can switch to - it throws a fake diagnostic warning

going all the way back in time... with the std system (aka as sold in 2007) with the NTG 3.0 comand system .... if you add a Viseeo MB-3 or MB-4 Bluetooth puck - you set its hidden dip switches to NTG 4.0 for it to operate correctly...
Basically a comand 2.5, 3.0, 3.5 and 4.0 are relatively similar units

I can tell you this, I wish they would fix that damn day/night/automatic dimming control. That is really my only gripe about mine. Other than sometimes the comand starts in the off or 0 position and I have to turn on or volume up back to where it was.
As to the problem at hand, maybe check your wire connection. Turn it a few times back and forth to make sure it has a good connection. Also check you settings on the Android side.

Hello,
this might be a stretch but I have a very similar android radio that installed in my car and now I am looking to add 360 cameras. I already have the reverse camera just trying to see what I need to add cameras in the side mirrors and also the front grille. The android radio has the inputs for 360 degree cameras. I know that if I connect the camera wires side to the directional wires in the mirror that will trigger the video to turn on for when that directional side is on but how do I get the front camera to trigger on? What wire do I need to tap into to have the front turn on? I don’t want it on all the time. I would only use it for maybe parking. Any help would be great. Thanks
