Mercedes c300 Aux fix
Panel come off very easily pull from the bottom is held on 2 clips i believe.
So the aux cable was hidden -_-
I pulled out the iPhone cable because who has a iPhone 4 anymore common lol
Aux cable clicked in place and i hid the old iPhone cable out of sight.
bammm aux went to Walgreens got a 6 ft aux cable for $7.99 compared the sound quality to Sirius and aux seemed to sound a bit better over all sound to iPhone cable 10x better hoped it help yall !!!
I already had the aux cable in place when I bought the car, but I found that compared to CD, Radio and Ipod connector, the sound was very very low. I had to purchase a portable amplifier to get the same amount of sound and quality for the aux port.
It has very long battery life, and when I bought it, there was an extra battery pack in the combo.
The F11 I purchased cannot be used while charging. If I could do it again, I may have tried the cheaper E6, hidden it and had it run off the car's power. This way it would have been a very clean, and OEM like solution.
I currently have a mess of wires in my cup holder, and constantly need to turn the unit on to use it and off whenever I'm finished. I may just purchase the E6 or a comparable amp and install it nice and clean.
I can't fault the E11 for not fitting my specific and difficult requirements for OEM ease of use, but overall, as an amp it is amazing.
Also I want everything in the glovebox so I don't have to mess with it so would you go with the E6 as you mentioned or another model?
I did a lot of research years ago and I found that the E6 and E11 are decent enough bang for buck. There were a few different brands out there that weren't as well known or from smaller companies, some people would say they are better.
If I were to do this, I would just play it safe and get the E6 since I already had a good experience with the E11. My main concern with the E6 is that people didn't think it was loud enough of signal boost, the bass control was lacking and that the battery life sucks. Basically an all around worse amp than the E11, but the E11 cannot run while charging, and I don't want to dish out the cash for the Monte blanc, which is better than the E11 and supports use while charging I think.
The amp doesn't need much power, so we can probably tap into any power wire, but the charging cable that came with the E11 is USB, so I think we'll have to find a cable with the same specs that isn't USB, or fabricate it to fit our needs.

Will, that sounds like a spectacular plan. I did remember we had a DC outlet in the glove box but I guess it slipped my mind. I just tried to charge the E11 while using and it wouldn't even allow itself to turn on while charging ...disappointing, especially from such a great amp that cost twice as much as the E6. Please let me know how it all works out, including the performance with your bluetooth device. I may be interested in a similar or same setup with no wires!
Codeblue, I am going to wait to see what Will's experience is with the amp and the DC outlet, it seems that it was working well with just the bluetooth device, so I'm hoping the same will be true for the amp. I'm tempted to just go through with it myself now anyways!
My setup:
CoolStream Duo $29.99
FiiO E6 Amp $27.99
Dual USB DC plug $7.99
Both devices are powered via the USB/DC plug in the glovebox. The CoolStream Duo plugs into the FiiO E6 and it in turn goes into the AUX connection in the glovebox.
In short I'm very pleased with the results!

I am very happy to hear about your results! Thank you for the update! I am most definitely going through with it! I frequently have passengers who want to play DJ, so I'll stick with the aux cable for now, but since the cool stream worked so well for you, I may just give that a try for an entirely seamless setup.

Btw, do you notice any increase in sound quality after using the amp? The E11 made my music sound considerably better imo.

I have been essentially connecting my device via aux into my E11 amplifier, and then from the E11 amp to the Aux port in my glovebox. The sound quality is the best it can because I'm using a wire, but I unfortunately have a mess of wires in my cupholder AND I have to turn my amp on and off repeatedly. If I got the E6, I would just have a single aux cable coming from my glovebox, and I would plug in and be ready for music. I would still have my bluetooth connected to the MB HU for calls only.
The bluetooth adapter would be for music only. I can only use the MB HU bluetooth for calls, I cannot use the MB HU for bluetooth music. If I were to get the cool stream, it would allow me to cleanly and wirelessly stream my music via AUX, without worrying about any cables.
The bluetooth adapter you used was a similar FM radio setup as a friends of mine. You need to pick a frequency that is fairly unused, which can be difficult, and even then there is lots of interference. I agree with you that it is flawed, but that is not due to the Bluetooth technology, but rather, the radio stereo method. But I'm sure you already knew that.
As for the W203 AUX, I used bought the infamous white clip to connect to the buried AUX cable and my wife has been happily using it for music and audiobooks on her long commute.
