Car Stereo with Bluetooth

Hi,
I was just wondering if anyone has a car stereo with bluetooth capabilities. I have been looking at getting one myself. For the longest time I used a treo 650 and had an FM transmitter hooked up to the audio port so I could hear my music and GPS programs over the stereo. Since the Touch only has the mini USB out and I have yet to find a fm transmitter that uses this interface I've basically been stuck using the rear speaker on the phone.
I have seen a bunch of car stereos that are bluetooth capable. I realize that they have to be able to play streaming music via bluetooth and not just handsfree to get the full "stereo effect". My question.... Has anyone tried this out or knows anyone that has used it. Also, how would hands free actually work via the stereo?
Thanks!
Aaron

hmmm..why not just get a bluetooth receiver with a 3.5mm jack. I'm currently using the itech bluetooth clip radio and am able to output stereo music from my touch to my speakers. It also doubles as my handsfree when i'm out and about.
As you mentioned you're using an FM transmitter hooked up to the audio port of your car speakers, this would be something very similar to your existing setup and probably a lot cheaper than getting those bluetooth speakers you mentioned

I needed to replace my car stereo as it is because the display didnt work. Just figured I would upgrade and get one that had bluetooth capabilities but it would seem either no one has tried to play music through a deck with bluetooth capalities here OR that not one has read the thread. Either way I think I'll at least spend the cash and see what happens. Wost comes to worse I just bring it back

Also.. I was going for the whole LESS wires thing.. Having a bluetooth reciever with a 3.5 mm jack that goes to an fm transmitter just.. yeah thats alot of clutter. I'd like to have it where the touch is mounter to the dash (as it is now) and all I need to do is push a button on the car stereo deck and the sound is routed though there. Having the phone plugged in is one thing but then having an fm transmitter and a bluetooth reciever and what not all over the dash is just a pain in the ass I think.

im using the sony/Erikson mbr-100 bluetooth stereo receiver with 3.5 jack. works great.

Is there anything specific I should be looking for. Just.. basically that it can played streemed music and not just hands free correct? That way ALL of the audio will play through the stereo.. not just the phone calls

The magic phrase you're looking for is A2DP. That's the Bluetooth protocol for streaming music from one device to another.
I got a Parrot MK6100 for Christmas, which is a dedicated hands-free kit that plugs into the back of the OEM head unit in my '99 Audi. The MK6100 is both a hands-free for the phone and a streaming music player for the phone too. It's excellent so your proposed solution might be perfect for you if your new head unit delivers the same functionality as this Parrot.
ALL the audio from my Touch is delivered through the car's speakers, including screen taps, TomTom directions, music and so on. There are some caveats though, caused by the Touch rather than the Parrot, I think:
Although the phone functionality works perfectly (it's actually very impressive - I just get in the car and it works straight away) playing music is more complex. I have to reconnect the phone's A2DP output to the car kit before I start the HTC Audio Manager, and I have to exit the Audio Manager before shutting down the car kit, otherwise it crashes and requires a soft reset for the Touch before it'll work again. I think WMP is more reliable but it doesn't integrate into the HTC Cube or HTC Home utilities so it's not a desirable solution for me.
I recommend you test the bluetooth streaming functionality with your Touch and the head unit before you buy the head unit if you can - you might find an incompatibility.

Sorry just saw this post was updated..anyway the clip radio does have A2DP and AVRCP support. Also, there is no need to use the FM transmitter. I mentioned similar..not use existing
but yes there will be a wire going from your speakers into the 3.5mm jack of the bluetooth receiver. If you want it completely wireless, then you will need speakers that have a built in bluetooth receiver..not sure where you can get one though..

I also have a question about htc touch and my head unit Alpine IDA X001.
I'm thinking to buy the Alpine bluetooth adaptater KCE-300BT which works with the head unit i have.
With this adaptater the head unit can display your last calls and let your browse in the phonebook.
Do you think that it will work with the HTC Touch (Windows Mobile 6) I have ??
Thanks

Here are the specs of the BT adaptater of Alpine :
SECTION BLUETOOTH
Version Bluetooth Bluetooth 1,1 CERTIFIÉE
Puissance de sortie +4 dBm Max. (Power class 2)
Profil HFP (Profil mains libres)
HSP (Profil casque téléphonique)
A2DP (Profil de distribution audio avancée)
AVRCP (Profil de télécommande audio/vidéo)

I have the SONY MEX BT2500 CD MP3 CAR STEREO that I had for Christmas and fitted myself. I am really impressed with this unit and it works really well, it also works as a bluetooth hands free.

Hello there,
I have Blaupunkt Hamburg MP68 and the bluetooth on it is excelent. Both handsfree & streaming working fine.

I have bought a Blaupunkt Hamburg MP68 stereo. I am very satisfied by this unit, it is a very complex device and it provides even a built-in bluetooth car-kit.
However there is an issue that I cannot work out: I can't get the stereo to download the phonebook from my HTC HD2 phone.
Both stereo and phone support the PBAP profile (phone book access), but the I always get the message "DOWNLOAD FAILED" on the stereo.
I have noticed that the "Dev A" profile (serial port) from phone's Bluetooth menu has a configuration option named "Local COM port", which was automatically set to COM2. Among the options, there is one called "ActiveSync" (as seen in the attached screenshot). I think that this might be the solution. Can anyone confirm my theory? I can't get to the car sooner than 4 hours from now.....

May be worth posting this in the HD2 forums as well. it has a much newer os with newer features then the touch does, by some 3 years. I do realise that this thread may be related, but people in the HD2 section may be more aware with any bluetooth features specific to the phone as well.

No need to do it, but thanks for the tip. 10 minutes ago I have tested the "ActiveSync" port setting and it works fine: all phone contacts are downloaded into the car stereo.
Cheers!

Grats for doing it then

how do I stream audio to my Jabra Stone?

Having trouble trying to figure out how to stream music to my Jabra Stone bluetooth headset. Any suggestions? Also having problems with my audio dropping in an out during a phone call; looks like the headset will disconnect in the middle of a conversation and then randomly re-connect again. Rooted running Myn RLS5.
Thanks.

For the streaming: To my knowledge, unless the headset declares to your phone that it has BT A2DP profile (aka, headphones/stereo audio), it won't work for anything other than voice commands and calls (aka, Handsfree or Headset profile).
Disconnecting: Put your phone on the same side of your body as the headset. If you're outside, it'll probably cut in and out due to ambient RF interfering. Believe it or not, your body has enough water in it to block the relatively weak BT radio.

When I look under bluetooth settings/bluetooth devices it shows:
Jabra STONE
Connected to phone and media audio

surprisingly....its now working at least using powerAMP, I'll try a few more apps such as Pandora and Youtube...only thing I did is re-charge the headset.

Odd. Might be that the Sense music player just doesn't like it for some reason. I have had zero issues with A2DP-capable devices on CM6 or 7.

[Q] Recommendations: Car kit - bluetooth mic plus 3.5mm stereo

While I wait for my One X to arrive, can anyone provide some in-car advice? I'd like to do the following:
Connect audio to in-car stereo via 3.5mm socket in glove box
Control pause/play via some kind of Bluetooth or in-line remote
Wired or Bluetooth mic for calls
Use my current universal dashboard mount
I have a 2005 Mondeo which is not Bluetooth equipped. In any event, what I've heard about others' experiences streaming stereo audio over Bluetooth kind of puts me off.
Does anyone know of anything that fits the above bill? I'm not going to be initiating calls while on the move, but for incoming calls, I'd like my current music/podcast to stop playing while the call is answered, with call audio coming from the car speakers and a separate (visor-mounted?) microphone. I've read about this device in another thread, but it doesn't look ideal and isn't available yet.
I've always previously used a Bluetooth stereo headset (not great sound quality), so I'm completely green with this kind of setup. My company's usual supplier wanted me to have some awful non-stereo Parrot car kit. I think I can do better than that.
Any ideas? Thanks in advance.

Answering my own post here - it looks like the Belkin CarAudio Connect with BlueTooth (F4U037tt) would do the job. Anyone tried one of these?

Car-stereo aux integration with iBOLT Dock

All, as there's a lot of questions coming in to iBOLT's customer service, and on forums about connecting the sound to the car-stereo speakers, using aux-out, playing music while a phone call is coming in etc. I figured we can start a new thread dedicated to all the variables involved. I'll try to make a summary below of functionality. If you have not seen the video or images of this product you can do so on www.ibolt.co/ibpf-33307
First, the iBOLT S III Dock solves the problem reported by many users that when they insert an aux-cable from the headset jack their Bluetooth device does not work properly. Since our Dock takes the Aux-out through the microUSB it works differently and from our testing, and end-user reports, the Bluetooth works fine.
Below is a run down on different options how to connect the Galaxy S3 Dock to car-stereo speakers for playing music and sound from all Apps.
BLUETOOTH OPTIONS: Please note that when using any Bluetooth hands-free device (headset, portable, built-in from car-manufacturer etc) with the Galaxy S3 you can choose if the connected device is to be used for phone calls only, for audio streaming or both. This depends on which Bluetooth profile your device is using. See attached screen shot for an example of the S III UI. This is from a Bluetooth U-connect system used in Chrysler cars (although they should all be the same).
1. Car-stereo systems featuring A2DP:
If your car is equipped with a Bluetooth hands-free system it may allow you to to stream audio (in addition to hands-free functionality) but only if your system features the A2DP (Advance Audio Distribution Profile). If it does have A2DP profile you will have the option during the pairing process to select the "Media Audio" in addition to "Call Audio" (see attached screen shot). If this is the case, the Aux-cable that's included with the Dock will not be used as Audio Streaming over Bluetooth is the preferred choice if your system is set up for it. In this scenario, simply hide the aux-out cable end or tuck in under the car seat or center console.
2. Typical car-stereo/Bluetooth systems:
If your car-stereo does NOT allow you to choose the "Media Audio" this means that your system is designed with the so called "Hands-free Profile", thus it is only able to be used for hands-free calling. For this scenario the aux-out cable from the iBOLT Dock should be plugged in to the 3.5 mm aux-in on the car-stereo, usually located in the center console or in-between the front seats. When you play music (or GPS Navigation sound) from your Dock to the car-stereo speakers and a phone call is made or coming in the Aux sound will automatically mute and start again once the phone call has ended. The sound quality when using the aux-out 9ft cable has been reported to be very good. Some users have indicated that the base is even better when using BT A2DP Audio Streaming, versus aux cable. This sounds very logical.
3. Cars without integrated Bluetooth:
If your car does NOT have a 3.5 mm aux-in jack but features a cassette player there's plenty of "cassette-to-3.5 aux" options to buy. Search at your preferred electronic retailer for the solution that is right for you. Once inserted the iBOLT Dock can be used for playing music through the car stereo as if played through the cassette player but at lower quality.
4. Cars with CD player only, no BT, no cassette player:
For cars that has neither 3.5 mm Aux-in, nor a cassette player there's some FM transmitters that features a 3.5 mm aux-in or with Bluetooth A2DP connectivity, allowing a way of connecting the Dock to the car stereo. We have very limited knowledge of this option as it has not been tested by us but theoretically it should work. Any feedback which models work well would be much appreciated!
There's more options and more variables but the above should provide a basic run-down. As there's many knowledgeable users on this forum, clarifications or comments are always appreciated. Connecting the phone's music to the car-stereo is something of high interest to a lot of people.
Our concept with the iBOLT S III Dock was to make the first (?) phone holder truly designed for placement on the left side of the steering wheel. Run the 9ft cable down the door seal and under the drivers carpet and/or seat up to the center console where power and aux-in is usually located. With the phone on the left side it is "out of the way" as far as blocking the view and more importantly, it is within finger tip reach for answering call or switching application. If you have not tried the application "CarHome Ultra" we recommend you do so as it's free for 30 days. Having a good "car panel" in combination with the right Dock placement, and the aux/BT set up as described here is very cool. The S III will become a integral part of the driving experience!
Finally, we strongly recommend connecting the Galaxy S III phone to a Bluetooth device for hands-free calling, regardless which option is used to connect to the car-stereo speakers for listening to music/app sound. To use the S III phone as a "speaker phone" while in the Dock works fine with regards to the driver hearing the other party. However, the party on the other end often hear an echo, a lot of background noise or the driver sound "faint" or like "in a tunnel". This is because virtually no Smartphone (including S III) is designed with a dedicated DSP (Digital Signal Processor) chip for cancelling background noise and echo when used for hands-free speaking. Smartphones don't have full duplex either when in speaker mode, which essentially means the microphone is at least partially shut down while the other party speak. The conversation is therefore similar to using a "walkie-talkie", where only one party can speak effectively at a time. Summary: connect your S III phone to a Bluetooth device from a respected brand manufacturer unless you're holding the phone to the ear when driving (bad idea!) or using a old fashioned wired headset.
I hope this long intro helps setting the stage for a good discussion about the best way to have the ultimate hands-free experience when driving!

NFC tag with BT speaker

so as those of you watching ces coverage might have seen a few manufacturers are using nfc in their bluetooth speakers to link them up to phones tablets etc.
NFC-enabled Bluetooth accessories
So why not do this with existing bt speakers by using a tag?
So at the moment I've got a tag on my speakers that will enable bluetooth so that the phone (n4) connects to the speaker (they have previously been paired) and phone and media audio gets piped to the speaker (speaker also has hands free function Gear4)
So what I'd like to be able to do is
1. tap the tag while the speaker is in pairing mode.
2. have the device turn on bluetooth
3. search and pair with the speaker
4. output media (but not phone) audio to the speaker
is this even possible? how would i go about it? I've been using NFC Task Launcher but don't seem to be able to mange to do it within this app.
cheers in advance

There is a specific NDEF Message containing the MAC of the BT device that you can write to pair. However this precludes using NFC Task Launcher or other apps to perform other actions. This is only supported in JellyBean and up from an Android side.

Sony Android 4.0 supports this too.
If you a tag with the special NDEF tag it will do everything you want. I think news version of TagWriter can do this. If phone is routed to the external BT device depends if the bt speaker support headset or not

Here's a video review/demo of an app I use called BT Tag Writer: http://youtu.be/u1z6-pa_1Wc
Just have the andytags nfc sticker on my BT media receiver. When I tap it, it turns on my BT on my phone and then automatically connects to the media receiver.

Thanks for this. Have now upgraded my Phillips Fidelio dock to NFC tap-to-pair! Goodbye horrible Phillips app!
Also, this works just fine with Samsung TecTiles.
