Galaxy S5: Bluetooth Issue

[mzdrati]

I have the same problem as the OP. I have a 2003 BMW 5-Series, and before Android 4.2, the Bluetooth worked perfectly. After 4.2- my phone pairs with the car, then disconnects and reconnects constantly until you just switch off bluetooth out of frustration. In my mind- the problem is definitely related to Bluetooth code used in the OS, as the problem appeared immediately after downloading the OS revision. No amount of unpairing / re-pairing, or phone resets have fixed the problem. I too am no longer even trying to fix the issue, as the BMW bluetooth adapter (called the "ULF") likely has to be upgraded (they cost $500, so that is out of the question) or the phone has to be rooted, and the OS has to run software that includes the previously-supplied bluetooth profiles. I do not know how to root, or how to install CM (and do not know if that would even address the problem). I really don't want to have to know all of that just to get handsfree bluetooth the work. Right now- I'm using speakerphone to make handsfree calls in the car (I'm a salesman in a large sales territory so this lack of functionality affects me a lot). It's extremely annoying. I realize that my car is 11 years old, but it still does not seem like it is too much to ask that Google address this issue.

Hi. I have just unboxed my Galaxy S5 (on o2) and was hoping that this Bluetooth issue that I was previously having with my S3 would have gone, but it hasn't.

Basically, I can connect to just about anything other than my car. When I try and connect to my car, it recognises the connection, asked for the pass code, says it is connected, but then nothing happens.

This issue is related to making and receiving calls in the car through the hands free system.

I know the issue isn't the car though, as I have tried various different handsets ,and they all work. Just not my old S3 or this new S5.

Any ideas or suggestions?

My car is a BMW 325Ci E46.

It is just so frustrating as I have to remember my little Jabra Arrow everytime (sounds minor) but when you've not needed it for over 5 years, it gets frustrating.

Thanks in advance.

Not Sure if you have fixed this yet but have you tried going to BMW and getting a software update or at least contacting them and asking if there is one for your model?

All the best

Try using a 5 digid pin code. Works for me on a bmw 6 series from 2006.

My wife drives a '13 328ix. There are no issues connecting with iphone, my old Galaxy Nexus, and my new S5. I can stream music from any device and make and receive calls. I can switch at will between devices when we're all in the car together but it takes some time to sync. Only 1 device can be connected at a time, obviously.
The device is not paired properly. All of the information is in the BMW manual or give your dealer a call and they will gladly assist you in any way.
The S5 will pair to just about anything from my wife's car to old and crusty aftermarket Pioneer stereos.

I am considering rooting my VZW Note 3 in hopes that there is a ROM that uses the pre-KitKat Bluetooth profiles. I do not know if you can root under 4.4.4, but BT does not work with Samsung's version of Android in my car anymore. It's absolutely infuriating.

The explanation behind this (and the sometimes seemingly contradicting reports) is the following:

Older BMWs (like the E39, E46 and earlier X3) have a Bluetooth Module that has a slightly faulty software. This glitch announces a car feature (3WAY) to the phone that the car doesn't actually support. With earlier phones (from the pre smartphone area and Android before V4.2) this didn't come to light because these phones didn't support that feature also.

Since Android 4.2 and later, the phone detects the contradiction (between announcing but not supporting the feature) and breaks the bluetooth pairing. Only solution (as far as those BMWs go) is to either buy a new bluetooth kit (google "BMW Bluetooth ULF Module Differences" (Bimmernav) ... cost ca. $450). Or patch your phone (requires rooted phone, some hacking talent, google "bmw e46 carkit bluetooth.default.so" (XDA Forums) for instructions).

I am driving 2012 Mazda 3. Used to have iPhone 4 and it worked fine with bluetooth: phone calls, navigators, etc. Now got Samsung S5 - and a problem: phone connection to car works fine, but there is no sound from phone music or navigator over bluetooth. Anybody knows how to repair it?
