USB question

Question: can the entertainment system find the thumb drive with songs if I buy a two into one USB connection?

As you can see with the pictures below, I have the Mercedes-Benz connection which goes to 64 pin then to iPhone connection and it barely keeps up with charging. I bought an aftermarket cheapie on Amazon and it barely was any better. Could I purchase one of those adapters Male USB that goes into two female USB‘s and connect in the thumb drive picture below as well as a regular apple USB to fire wire connector and still be able to access the thumb drive as well as have a better charging rate instead of using that funky Mercedes-Benz only connector??

Again purpose is to get a better charging rate because that Mercedes-Benz only connector barely puts out any charge to the phone and if you’re running Maps or Twitter or anything that use a lot of phone power, the phone barely keeps up and in a long drive it loses power compared to a regular USB connector.

For some reason, it removed my first picture, which is the most important one again here’s what I’m dealing with.

Not sure. I use an AC charger with a long cable up to the front to charge my fone. Once it's charged enuf, plug it into your mystery cable.

What kind of bull**** answer is that? I’m not a troll. I’m asking a legitimate question. If you don’t like the feed, then your phone has a capability to move to the next thread. GBAGASYITH 👍👍👍👏👏

I use the USB port located in the armrest console to charge my phone and it works well. Have you tried this or is it an option that you do not have?

The USB splitter cable shown in the OP's opening post is described as a power cord. It likely has no data conductors. You can charge 2 devices from a single USB port with it, but it's not going to couple 2 media devices into a media player.

AI gives the response

Based on the search results, "GBAGASYITH" appears to be a slight misspelling or a variation of the name
Ghaith Ouerdiane Bacha (@gooba_official), a Tunisian Instagram user who posts content in Arabic

Not sure if that helps.

Everyone's requirements are different.

Personally, I doubt that "charging" and "music transfer" can happen on a single USB sharing cable.

Us? Both our phones instantly connect to the GLK "audio" system via Bluetooth.
So, if we want to listen to music, the music is on the phone and instantly accessible for the GLK upper console.

As far as "phone charging", we have an ultra-reliable Anker adapter that we plug into the 12V outlet on the backside of the center console.
We have used that during times when our home power goes out ... it will charge a phone in less than an 1/2 hour.
(no need to run the car).

( a couple of side-notes:
1. the image wasn't shown in your first post because you (inadvertently) inserted a "space" for the filename's extension - why it didnt show up
2. "GBAGASYITH" is a nonsensical acronym

I'm always on the lookout for good acronyms. One of my favourites in PEBKAC.

yeah, that’s exactly what I thought. I did find another one on Amazon where one line is listed as power only. And the other is listed as data and power. I guess I should rephrase a question is anybody else experiencing the same phenomenon where the Mercedes-Benz specific connection for iPhone or iPod does not charge fast enough. I’m assuming since I purchased a different chords for it one being the original Mercedes-Benz product and the aftermarket that this is just the way the connection is because it’s 64. It was designed to data transfer and power a iPod, whose power requirements are much less than a iPhone. Would that be a correct statement??

👍👍yeah, thank you for the info. I have never really used a 12 V outlet in the back for anything then inflation.

not a troll whatsoever, but if you want to find your way over to Twitter or true social, I could absolutely devastate you where I don’t have to worry about being banned no, it’s a legitimate question. That’s what I hate about the Internet is not only other trolls, but there’s just this mindset that since you’re anonymous and hiding behind your iPhone, you can say the most outlandish and disparaging things without having to worry about consequences. The Internet is a wonderful thing and allows us instant searches and for academic sites you can pull up any piece of data on any empirically based study worldwide at your fingertips instead of spending hundreds of hours at the library. But with it comes the bad a.k.a. people like yourself, who instantaneously act like a complete a$$ for no apparent reason except that you can get away with it because you can, as I said before, hide behind your iPhone. Completely unnecessary there’s plenty of hate to go around and I would recommend that you exercise your hate on a more appropriate sites such as Facebook, Twitter/X, TruthSocial, TikTok. That’s a more appropriate place for that childish, passive aggressive behavior. I’m not gonna block you but just know whatever you write in response. I’m gonna ignore because I’m here to figure out an issue with the Mercedes. I’m not here for beta-male cucks trying to act like bad asses. GFKY. 👍👍👍🇺🇸🇺🇸🇺🇸🇺🇸

USB connections must meet specific standards. For USB1.0/2.0 it's (maximum) 5 volts and 500mA (2.5 Watts). Another complication is the device you're trying to charge has to "request" the maximum current and won't automatically receive it. Otherwise, it might only get 100mA. USB 3.0 can deliver a variety of current levels from 0.15 to 0.9mA (4.5 Watts).

Newer specs can deliver higher voltages and current.

You make an interesting point here. If the OP is using a 2 conductor cable (power only), there's no way for the attached device to request a higher charge current, so only the minimum is supplied. There are USB current test tools available (
Amazon Amazon
) that provide a way to check charging current.

thank you and I had a friend locally telling me the exact same thing and he’s coming over tomorrow to make some diagnostic investigations onto both ports to see what I need but with all that sad I did find a splitter which one is Data only and the other one is power only. I placed it on hold until he shows up but he assures me that the stock Mercedes-Benz information system will be able to find the drive attached to the data port. The phone only needs charging obviously if I want to use it in conjunction with the sound system, I’ll do it via Bluetooth so there’s no reason for a data port for that as well as I’ve also found it interesting that the Bluetooth connection with the phone is significantly louder than with the thumb drive or any other source even the Sirius radio I would say the Bluetooth volume is almost double that of any other music source which I thought was rather interesting. Anyway, I just want to thank you for that and I’ve already printed it out for one of my friend comes over to the garage.

Yea, wife and I found it way easier to connect via Bluetooth for music ... sometimes the GLK will automatically connect to her phone or my phone ... easy to select which one.

As I mentioned, we use an Anker charge adapter in the 12V plug on the backside of the center console. It has a USB 2 and USB 3 slot ... we use USB 3 for faster charging (charging and Bluetooth play can work simultaneously)

@calder-cay I have had a charger plugged in the same as you and I have just run a cable up front to charge. Works great. Simple solutions are the best

Yea ... after we discovered the 12V outlet at back of center console, I bought the Anker.
Our Samsung smartphones shipped with a USB 3 charging cable that is, I think, about one foot long.
So, we can lay the phone down on the fake-wood center console sliding drawer (whatever it's called) and charge.
Very convenient and the cable is non-intrusive.

( admittedly, I can do the same with our 2001 Jeep Wrangler's cigarette lighter outlet, but it charges slower )
