This is partly true. It could be a compatibility issue. What year and model is the car?
What ROM/kernel are you using?

Blutooth is broken on 4.2.1 you need to wait for 4.2.2 or use a custom kernel like Franco's Kernel.

Thanks everyone. It is a 2012 c300. I am running stock 4.2.1 rooted.
Should I try another kernel?

Mine connects to my 2012 Ram on unrooted stock 4.2.1 with no problem. OP, see if there is an update for your vehicle from the dealer. My '12 has already had one due to an issue with the HDD in the radio.

Just called and nothing. They actually have never heard of anyone trying to pair their tablets. I had a feeling they would not be much help.
I am wondering if I try to go to another rom.

You're on 4.2.1 stock?
Wouldn't hurt to try. I'll try connecting to my 2013 Jetta tonight. What is it you're trying to tether? Audio, I suspect...

Cars usually only connect to Phones via bluetooth because phones have different bluetooth profiles than tablets since phones have changes in their framework to allow phone calls.
most cars connect to the phone so you can use the phone hands free. tablets dont have hands free bluetooth profiles thus is probably why your Mercedes isn't linking properly as the tablet doesn't support syncing phone books and phone calls.
Someone else may have paired theirs with their Dodge ram but they most likely paired it for Audio to their audio system but not their navigation/phone system.

I got the same problem next time will buy a BMW.

I had issues connecting an android 4.2.1 device to an AUDI A6. gave up after a few days, even took it to the dealership and they couldn't figure it out.
for some odd ball reason, android bluetooth just doesn't work right. I tried all my apple devices (ipad and ipod touch 4g) and it connected instamagically to the car.

Let me know how it goes for you and I will try the later rom

Nexus 4 aokp sound not working

Hey so I've been running aokp for a few days now, and suddenly I noticed that the sound isn't working, not for notifications, not for music, videos, anything. Not even when the headset is plugged in. So I flashed my stock Rom backup and it still isn't working, any ideas?? Thanks!
Sent from my Nexus 4 using xda app-developers app

Ok this is weird, sound just started working on my stock Rom. Haven't tried aokp yet, the restore backup of stock Rom took 30 minutes and I need to sleep soon so I don't want to risk hanging to stay awake for it, it normally takes 3 minutes to restore backups though, idk what's wrong

No, I searched on the internet for the newest version of aokp and used that one

I wish I could help but mine is doing the same thing. I'm on CM11 nightly though so I thought it might be that.
Any help out there?
Sent from my Nexus 4 using XDA Premium 4 mobile app

Have you guys tried a full wipe with a factory reset? Also testing the device before bringing back any apps you have backed up? Sometimes you do a full wipe only to bring the problem back with a backup.

My phone is having the same issue. I've rooted and installed many different ROMs. The last one I tried called Beanstalk installed with all the sound working properly but on the first reboot, the problem came back. I tried wiping an re-installing but the problem is still there, so it seems to be the luck of the draw. There is an app called Soundabout which you can install to route the sound to the speakers, but you would then have to go into the app to route the sound back to the headphones when you need. Very strange. I've seen many posts on different boards of people with the same issue but no true fix. I need to find a good android developer who knows the code well that could probably figure this out...but who that man could be I just don't know...
Are you still facing the problem?

cm 11 grouper Bluetooth issues

Hi...just wondering if anyone else had a problem with Bluetooth on Nexus 7(2012) after cm11? Mine won't work after Jan. 20 nightlies. Have to keep rolling back to that point.
Sent from my SAMSUNG-SGH-I337 using XDA Premium 4 mobile app

Yes this also happened to me after the 1-20-2014 update.
Bluetooth (enable-disable) goes in a loop once the button is pressed.
The error message has something to do with the Bluetooth Service.
Since CM11 is still in the nightly stage, I think we cannot do anything except to wait. We cannot file a bug report anywhere else.

Annoying sound

Hi,
Since a few days my phone is making a annoying noise while playing music or watching a video. It kinda sounds like a little fracture in a cable or when you keep your phone close to a speaker or old television, but then for 0.5 second. It also happens irregularly and also happens when using headphones. I'm using Viper xHifi, but it doesn't make a difference when it's turned off. Does anyone know what it is and how to solve it?
Thanks
Sent from my Nexus 4 using XDA Premium 4 mobile app

When it started, did something happen? Like .. did you drop your phone? or ... maybe just installed a new application? .. maybe changed the kernel settings?
Also, which ROM/kernel are you using?

I have been having this exact same issue on my nexus 4 and nexus 5... Both phones are rooted, stock rom, and on the latest version of Franco kernel. I have been looking all over for a solution but nothing yet...
Sent from my Nexus 4 using xda app-developers app

I'm currently using psx kit Kat, it started suddenly. I haven't recently installed an app that possibly could have any influence on the sound. I think I've had it earlier and flashing a new rom fixed it, but I currently don't want to switch roms and I think it's strange that it happens so sudden.
Sent from my Nexus 4 using XDA Premium 4 mobile app

I switched from franco to hellscore and it got a little better... Now it only seems to happen in YouTube. Will keep trying different kernels and keep you posted

Only happened to me once using Poweramp with headphones. Never happened in Google music or via Bluetooth/speaker.
Sent from my Nexus 4 using XDA Free mobile app

I've got a bluetooth speaker for a few days now and with that one I don't hear that sound. But it still happens with my phone speaker and headphones, regardless of which app.

Maybe it has something to do with the music buffer size? I don't know how to increase it but a hiccup like this sounds like the buffer might be set too small and it's this split part of a second sometimes it takes to reload the next piece of music into the buffer?

Now running carbon rom nightlife and hellscore... Noise is completely gone!

I'm using slimkat and it happens all the time on Power Amp and Spotify, no issue on Player Pro or Google Music.....strange. Anyone have a solution. I love Slimkat/Spotify/PA.......pleased help.

In Poweramp go to settings/audio and search for the audio buffer setting and set it to highest. See if this helps.

Tried that....no change

OK, was worth a try. Poweramp is weird in some things anyway. For me, v4a doesn't work with Poweramp when using headphones. Only on speaker and Bluetooth.

About your issue. I have been using viper audio and had similar problem. The only thing that solves the problem was exchanging one file. I don't remember the name of that file but I'll try to find it for you.
On slimkat thread someone write that deletin dsp manager should resolve my issue. I will report later if it worked.
Tapnięte z mojego podrasowanego N4.

Same thing happens when playing music with poweramp through a headphone jack. It's kind of like a 1 second screeching or something, quite annoying.

Yeah its annoying i have the same with aokp with helldoctor and tardis. I will try viperaudio to see or it will be fixed and for advanced music listning

Trying slimkat 5 with stock kernel....if it works that would be great.

No changes. Glitches.....going back to hells core due to better battery life.

I don't use PA or spotify anymore, wimp was the solution for me....I pay the same amount of money as for spotify and I have no scretching and have free data transfer for wimp in my carrier plan...

same problem here on simple aosp + franco. went to cm with no sound problems but apps fc all the time! hope we find a solution soon
