Anyone able to test this?

Turn up your car media volume to MAX but have no music playing on the screen. Can you hear a whining or humming coming out of the car speakers?

Yep I have that too. It's due to the poor quality of the USB audio box, which throws back some audio feedback into the speaker loop.

Figured as much - will try adding a ground loop isolator.

can you PM me a link to the firmware.

So my box came with this audio box only and I dont see any 3.5 mm audio cable. Am I missing a cable? Thanks

Updated: found out where to hook it up. Only issue left is No Audio when switching over to android (Youtube or Spotify). It's fine with oem mode (radio, Bluetooth from phone).

I have the same issue and I disabled the sound enhancements but still can't get the sound. Only hamming. Any advice I attached what I have from the box.

Can anyone tell me where you guys put the gps antenna for a good signal

No sound only with navigation.
 

Hello.
I made this 9.33 inch android display connected to my mercedes through bluetooth directly but no sound with only navigation. Music and any other sound works well but no sound only for navigation voice guidances.
Does anyone has this issue?

Hi, I believe I followed this guide well, but I have a big problem. The android screen works fine, but I believe something went wrong when reinstalling the center console, I didn't test anything before putting it all back together, but essentially my clickwheel, my touchpad, my AGILITY selector, and I believe my volume controls (unsure because no audio at the moment) are all not functional; furthermore, when I press FM/radio to access stock MB OS I just get a black screen, and if I put my car in reverse my rearview camera doesn't come up, just again a lit black screen. Any advice on what I must've missed? Will probably open it up and recheck all my steps after memorial day weekend.

Thanks!

I had had the same problem and found out that I accidentally hit the power button on the center console that turns off the factory screen.

This sadly did not help me in my case :( I’m sure you were still able to use other functions but I can’t use anything shown, but the higher buttons like AC NAVI/Radio/Media all work fine

Can these systems connect to android phone wifi for tethering? just so i can use the data from my phone to the car?

If you’re talking about using your phone’s data as a hotspot for the car, yes you can do that.

cool. thanks! thats exactly what I wanted to know

Thank you for posting this! I installed mine last night without incident. I don’t think I wouldn’t have figured it out with out the instructions you posted.

Thanks!

Can some one please tell me if there have Audio Delay in the unit? as the Seller said there's 2 Sec Delay but it cannot be fixed so i was wondering if any one have those issue plus any Lag when using maps and other apps?

if not could you please mention where you bought ur unit from so i can buy the same one please

I have the same issue, i dont know how i can fix it
AUX and BT both.

Did you connect it to your mercedes with BT?
Can you hear the navi instructions through the car speakers?
In my case, only navigation instruction sound do not come out. Music and movie everything is fine but no navi sound.

is it only for youtube or you getting delay from Sportify as well? what other music apps u use?

All kind of video apps have delay, Sportify too. it seems to happen with music apps as well but i can not recognize it. I just think cuz it takes quite a bit time when i change to next song.

There seems to have an update version 4.1..this pic was sent from there support when I asked for device version I don't know what is changed as I don't have the unit yet
