Incredible + A2DP on Kenwood kiv bt-900?

Just had the new kenwood deck installed... Should do almost anything. I have my incredible paired up and calls are clear. Problem is A2DP audio streaming. Does not work. No A2DP device is found. Yes, the manual gives directions to play streamed audio once bt is synced. Well, its synced, got my phone book on there, and calls are being made.
Any thoughts or ideas to get streaming audio?

I don't have any help to offer, but I am experiencing the same problem with my Pioneer FH-P8000BT. Pairs for phone calls with no issue and everything is clear, but the radio does not even "see" the device as being available for A2DP.
I previously paired a few different HTC phones (all running Windows Mobile) with this radio with no issues. I'm hoping it's a simple fix, but I can't find a single thing in the settings that I haven't played with to try and get it to work.

I have an Alpine HU with an Alpine KCE-400BT bluetooth add on. My streaming audio is working, although I don't get any song/artist info on screen. I do have an issue where the phone doesn't sync up all the time. It syncs up great in the morning. If I stop for gas or something (turn off the car briefly) and get back in, then the radio won't see the phone until a call comes in or is started from the phone (or I toggle BT on/off).
You might check with Pioneer on any firmware udpates.

My incredible works great with my Ford sync system. It always connects, calls are loud and crisp, and streaming bt audio works great. I use it to listen to Pandora all the time.

I have seen other people post issues with having bluetooth on the phone enabled before the car is on. If you turn the car on first and then the phone's bluetooth they said it worked fine.

I have Kenwood HU and my phone won't pair with it. my Blackberry Paired with it fine, and even did A2DP, and worked awesome...now......nothing.
Been looking for some answers as to why, but after calling Kenwood they said it's a software update that is missing.
however, seeing as some people are getting it working fine....I am suspecious.

Kenwood 4160 working, actually better
My 4160 and serveral WM units worked, but the A2DP always had to be turned on by going into the menu every single time I wanted to listen to anything from the phone, but the Incredible does it by itself every time perfectly.

I have a Pioneer AVIC N4 and the audio for both calls and music works just fine out of the box.

I have the kiv-bt900 also, and it is my understanding that it does not have A2DP. I believe the A2Dp in the manual is referring to the KIV-700 with the add on bt module.
From page 67 (of the downloaded manual from Kenwood)
KIV-BT900
Supported Bluetooth Profiles:
Version: Bluetooth Standard Ver. 2.0
Profile: HFP (Hands Free Profile)
OPP: (Object Push Profile)
PCAP (Phone Book Access Profile
SYNC (Synchronization Profile)
I thought it had it too when i bought it. Maybe a future update will enable it though??

What does A2DP mean please?

it stands for Advanced Audio Distribution Profile. In simple terms, it's stereo audio transferred from one device to another via bluetooth. Example: Music from a phone/mp3 player to stereo bluetooth headphones, head units etc..

Thank you.

Well damn. The deck was sold to me from car toys (local vendor) under the pretense that it would do zune (works great) and A2DP...
Usb works great too... I was thinking of formatting a laptop drive to the mac file system (hfs) and hooking it up to the usb port to get a200GB drive of mp3 and video since it supports ipods. (works on xbx360, why not here?)

OK so a small fix, but not the end result.
with my Kenwood head unit I can make it work as long as I don't let it download the phonebook. and that is no problem since the phone sits on my dash in the car dock. but the problem is that EVERY time I start up my truck, or after I end a call it asks to re-download the phonebook.
it kinda irks me, but I cannot get it to stop asking, no setitngs on the stereo work.

I emailed Kenwood about possibly releasing a firmware update to include A2DP to the kiv bt900. They responder saying that there isn't enough demand for the feature for them to create a firmware update. So if we get enough people contacting them and requesting that feature, they will release and update. So you guys should all contact them to increase the demand for this feature. Hope this helps.
Here is exactly what they responded:
"I understand that you're inquiring about the KIV-BT900's Bluetooth features. We do apologize for any difficulties that you've experienced with this item. Unfortunatley, we cannot assist you with any firmware updates at this point since this model was just recently released to the market. Our company has not received enough demand for this feature which prevents us from developing or releasing an update for the KIV-BT900 unit. We may release an Bluetooth update in the future, however it's hard to determine at this time."

I'm willing to start complaining and sending some emails out to them. What email address did you send it too? I just got the player and that is def the only thing missing to make it complete for me.

I tried emailing the regular support channels and got the below message.
Thank you for contacting Kenwood USA Corporation. We value you as a Kenwood customer and appreciate the opportunity to be of assistance.
I Understand you are inquiring about any updates to allow the A2DP profile.
There is currently no available updates and there hasn't been information on upcoming updates for the A2DP profile. We ask that you check back at a later date to verify if one is posted through the www.kenwoodusa.com website.
We apologize for any inconvenience.
Please feel free to contact us again with any additional questions.

I spoke with a rep and they mentioned that A2DP missing from the unit is the most often called in issue about the unit.
I have a KDC-BT948 with the same issue. They removed A2DP and put in Pandora instead..and it only works through iPhone, which then uses up wireless data on a cell phone plan. So Android, MS phones, and any other bluetooth device can no longer be used with a Kenwood Car Stereo. Someone at Pandora really made an impression at someone in Kenwood. It is too bad that they are limiting consumers with their choice which ultimately limits their sales and increases complaints.
Should have everyone go do this and request a fix.
Go to the Kenwood Contact page and send an email
This is what I sent
I have purchased the KDC-BT948HD radio.
Where I am overall happy with many of the features, looks, variable colors, and excellent sound quality of the unit, there are several things that I am extremely dissapointed in and would like to see an update released to resolve them.
1. SMS Received message on the unit: Might be useful to some, but to me it is a dangerous distraction while driving, especially at night. It has me take my eyes off the road to look at the unit and makes me want to look at my phone to read/send texts. Texting and driving is illegal in many states and there should be a way on the unit to allow a selection to turn this feature off.
2. BT Audio (A2DP) is missing. I have an Android phone with my music on it. Alone there are more Android phones than iPhones in use today. I wanted to have Bluetooth streaming audio so I can play my music from my phone to the unit. For such a high technology unit, it should be part of the firmware and flexibility to the consumer to use their device with more options. The previous year units had this enabled and seems to be disabled now replaced by a focus on a wired Apple connection and Pandora. Forcing use of Pandora also forces consumers to use up data rates on their wireless plans. If A2DP were enabled, more consumers could enjoy the product integration with standard BT devices offered by Apple, Android, Microsoft and many others. All could enjoy the music and audio applications on their devices including Pandora. I would like to request that A2DP be added to the firmware and source selection on this device. I should yield increase product ratings and sales as web searches show many complaints about this issue.
I would value your feedback on these points and potential solutions.
Best regards

Bluetooth version & BMW music streaming

I wondered if anyone can help with my query regarding getting music streaming to a BMW 320ED via Bluetooth?
The good news is that I can get my Galaxy Nexus (GSM 4.1.1 stock software) to pair with the car and I can get music playing via Bluetooth, but I can't see the artist information. The car screen informs me that the device doesn't supporting sending track information, or something along those lines.
What frustrates me about this is that my friends iPhone 4S does stream the track information as well as the actual audio. I Googled to see what Bluetooth version both phones use, apparently the iPhone 4S is Bluetooth 4.0 and the Galaxy Nexus has 4.0 capable hardware but only 3.0 features are available due to software limitations.
Is this true? Is once of the differences between Bluetooth 3.0 and 4.0 the ability for track information to also be shared? I was using Google Play Music if that makes any difference.

I've done some more research about this and thought I would update my post, just in case it's of help to anyone facing a similar issue. Turns out the Bluetooth protocol/profile AVRCP is responsible for streaming music tags to the car stereo, but only AVRCP 1.3 and above. Unfortunately the Galaxy Nexus only supports 1.0 by default but CyanogenMod 10 has built in support for 1.3 since roughly the 14th September nightly.
Should be able to test it out next week at some point. Why are Google so bad at supporting the latest Bluetooth features? I've always found this with Google experience devices to lack in this area where other manufacturers support the latest Bluetooth features.

Dodge Uconnect 430 and Sprint SGS3 woes - MAP compatibility

Some of you must own a Chrysler/Dodge/Jeep vehicle with a Uconnect stereo in it, right?
I've been all over the google search, the Dodge Forums, calling Chrysler's Uconnect dept, etc. and no one seems to have any clue what their talking about. I know that XDA is knowledgeable about all things phone. Searching doesn't get my exact questions, here's an unanswered one for the HTC EvoLTE (http://forum.xda-developers.com/showthread.php?t=1667801). The Ford SYNC systems have a similar problem.
I have a 2012 Dodge Durango with a Uconnect 430 RBZ stereo. It announces that my phone (the Sprint SGS3 with 4.1.1 LJ7 stock non-rooted (for now)) is not compatible with the Bluetooth Messaging Access Protocol profile or MAP-profile necessary to announce and control the SMS messages on my phone. There's a service on our phones that runs constantly when the bluetooth is enabled called MAPSamsungService, which after googling/reading/searching, leads me to believe this is the messaging protocol that the Uconnect desires.
My questions are:
1) Why won't this radio identify the MAP process of the SGS3 and connect to it Are there ROMs that do support this? (CM10 reportedly does support this http://forum.xda-developers.com/showthread.php?t=1916902 - but I don't like the CM10 camera....so...yeah)
2) Has anyone had success in getting the SMS messages functionality on their Uconnect
3) Has anyone had luck with getting your contacts to properly sync? All mine are Google Contacts, and it is VERY random which ones show up. (I have just less than 1000 contacts, which is apparently the upper limit for these radios)
[just in case this shows up in google searches, I have learned that USB drives connected to the Uconnect need to be in FAT32 format and you can only move 2048 songs over at a time to the HDD, so load up multiple flash drives for the transfer. must be constant bit rate not VBR, 1000 folders is limit and 20k songs]

as a former u-connect owner and current audi interface owner, let me offer the following:
When sold, the technology in any car is about 2-5 years old. meaning it was designed to interface with phones 2-5 years ago. so if you have an old phone, it will probably work great!!
Chysler never offered a flash or upgrade to the original uconnect system, but that was supposed to change with the RBZ. My brothers at the LX forum have reported that is not really true. There are some systems that allow you to get around this with aftermarket HU but not what you are looking for.
No way to know what ROM's will work or not because of your specific situation. There is a mammoth black hole where all BT protocols go...no one seems interested in making it generic.
We currently own 2 vehicles under the VW/Audi brand and a Ford with a Pioneer HU in it. My EVO LTE phone book will update in the VW, but not the Audi. Same system, right? In the Audi, it will frequently not sync. one vehicle has different software and Audi cannot flash it. no worries on the Pioneer HU though.

TLDR -> Car companies suck, wha, wha, wha
-----
Thanks for the reply and your experiences. Speaking separately for all the tech they put into every aspect of the car...... I would figure that in 2012, these car companies and their stereos would learn their lesson and start to evolve. I guess we need a Uconnect forum on XDA to really get things heated up! If anyone knows of a site for ROMs and such for these systems, please let me know, I'm willing to take the plunge.
I had an aftermarket Kenwood in my 2000 Jeep Grand Cherokee that I traded in. It synced with my phone perfectly, downloaded all my contacts, but didn't have the ability to read SMS messages (it also had a tiny display). Bluetooth worked well, etc. it just became a real piece of **** car that needed to be replaced.
The latest CM10 logs indicate that MAP functionality was fixed on 11/23: http://mobile.cm10log.appspot.com/?device=d2spr
I really wish that the CM10 camera and data connectivity didn't have so many issues, otherwise this would be a non-point and I'd be happy as can be with full functionality. What I find troubling is how many opinions there are about these different car systems and their compatibility. I understand your point about Bluetooth standards being quite a jumble. You should be required to support them all if you are going to use it in your device. I'm going to back to dual booting CM10 to see if I can get the MAP to work with the Uconnect system.
Then there's the confusion of all these systems. I have read links where a Stock Sprint SGS3 running 4.1.1 worked perfectly with MAP in a toyota prius. You ask Samsung and they say that MAP is not supported by the SGS3, their fact sheets would indicate the protocol is missing. But it was supposedly included in Android 4.1.1, but no one can confirm that.
It's just very disappointing when a company touts a technologically advanced car that can do things like read your SMS messages, display album artwork for songs, play songs from USB sticks, has ipod connectivity, etc. Can't seem to A) do any of those things well and B) offer absolutely ZERO tutorials and guidelines for making the above features actually work. You have to sift through forums to find out that a USB drive needs to be FAT32 formatted!
I just added 26.5GB worth of music to my HDD in my Uconnect 430 RBZ. I ensured that the album artwork was correctly linked with the ID3 tags in all of my music, a painstaking venture to say the least that I was meaning to do for a long time, however NO artwork actually shows up. It did finally all sync over and there are some things that it does "well" but far more that just miss the mark for no other reason than laziness and profitability. Just saying you can do these things is more profitable than actually making them work consistently - OR having knowledgeable people that can help you when you call in.
Overall, I guess I should be happy that it does what it does in the least. I understand the product cycles for cars and the tech is most likely 2-5 years old. Like everything else in this world, hopefully they'll improve their cycle time for updates. Then again, out of sight, out of mind. They have your money, who cares if they add any new functionality. Most cars aren't impulse buys like phones tend to be.

You can use any camera it does not have to be the cm camera. You can flash the stock or the 4.2 or even the note2 camera.apk. Also you xan flash your uconnect with a new firmware

Bluetooth AVRCP 1.5?

I haven't seen many threads on this and I am curious as to why it is not a concern for many Android users. Maybe it is because many Android users did not move from Apple like I did. The fact is, Apple is still superior to Android in terms of vehicle bluetooth connectivity. The more you need to look at and operate your phone while driving, the more dangerous driving becomes.
The difference between AVRCP 1.3 and AVRCP 1.5 primarily is the playlist selections. Since my car supports this, with 1.5 (iPhone 5) I would be able to see the contents of my library and browse/select music. Then I switched to a Nexus 6 and didn't have this feature anymore. Just a couple days ago I got the Nexus 5X and I am surprised they didn't change this with Marshmallow.
Is Apple always going to hover over Android with their updated bluetooth stacks?

Seems ridiculous that this is still a problem. Its as if no one want to shed any light on this. Talking about this and no apps that expose the Bluetooth stack and avrcp versions to the users who don't know any better. I would be nice if this was a separate module that could be upgraded independently so users could get the functionality they needed. Companies like Samsung rolling there own stack and adding feature is not a proper fix. This should be Android standard.

I have always been thinking the same thing, why is the
bluetooth stack from Google missing so many features.. I have tried both Samsung and HTC and their stack is just so much better.. But I always end up with a Nexus phone again and longing for a better BT stack...

BT overall sucks with the 5X. Hissing, popping, laggy stream kills it for me. It can't keep the connection with my car either while iPhones were trouble free. It's almost 2016. Are we asking for too much?

Thought I would add a way to get some info. This is from android.stackexchange.com/questions/43667/discover-version-of-bluetooth
Turn on bluetooth by going to the home screen, clicking menu->settings bluetooth. Pull that to enabled. Make sure it is on.
On the home screen, click menu -> settings -> applications -> 'running' tab.
An item appears called: "bluetooth share".
A screen pops up with information about the program, but it is sparse.
Also you can go to All tab and "Bluetooth Share" to see its actual version number. Though that might not be very helpful.
Also and old article discussing some of the bluetooth stack changes in Android for what its worth.

Sorry for the broken url but I've not posted enough on XDA to be allowed proper urls.
I'm going to try keep posting things I find that might be useful just consolidate more info in one spot. Trying to make this problem clearer for myself.

Is there anything new about AVRCP 1.5 features? May it possible to build and install a custom kernel with bluez support (which afaik has avrcp 1.5 support)?

BT audio in my car...

I've just got a new (to me) car & BT isn't playing fair... It seems to be a known issue, but I'm keen to get it working...
The phone functions are working fine, but the music/audio function isn't. BT audio isn't showing up in the cars interface, nor on my HTC 10 when connected.
Is there a way to add more profiles or make the phone more visible to other BT devices. The issue is 100% with the car & it probably doesn't support enough protocols, but I'm hoping there's a useful app to help...

Make and model of car?
I had a similar issue with a BMW and my wife's PRIV.
Had to update the BMW software. They had it on their website for download and install.

The car's a Porsche Cayman. I'm not sure there's a firmware update available... Feckin cheap German engineering!

My last car was a 2009 Nissan Altima and it had a horrible BT stack. I had to do some workarounds to even get a call to work properly. Newer cars seem to do much better these days.
Like Anandlal suggested, I'd take a look and see if there are any firmware updates for your car. Some makers have them available for download and make it easy to do yourself (Ford comes to mind here). Others may require an update to be applied at the dealer, and that might incur a charge. If they have to do it, you may want to have it done with an oil change or other service to minimize cost and inconvenience.
I feel for you. Cars can be picky and if you get a lazy manufacturer that doesn't update their stuff, you're SOL. I'd hope that for they'd take good care of you considering what you paid for that Porsche.
Good luck!
