I got a Bluetooth device to use in my car and it works fine but when I'm using GPS while navigating, the Bluetooth signal becomes very flaky. Is this normal behavior?

I use GPS and bluetooth all the time to track my bike rides using Sportstracker and whilst listening to music on my BT headphones.
Sometimes I have the phone in a zipped up shorts pocket and sometimes in a leather shoulder satchel thing that sits across my chest.
On rare occassions I'll get a small dropout in audio. I think it may be due to other radio interference as I ride around, but it's only for half a second or a second.
Hm, maybe I got a slightly faulty device. Its pretty much pointless for me to try to listen to music via Bluetooth while using GPS, its just that bad.

Having Bluetooth "Handsfree" and A2DP connected at same time causing severe skipping
Hi....I know there are a lot of posts regarding skipping while playing MP3s over A2DP. My problem is perhaps a little bit different because I've narrowed my problem down to the handsfree bluetooth service.
Here's my situation with my unlocked HTC TyTN II using the stock HTC ROM and with no registiry modifications (bitpool, etc)
If I have only A2DP connected and streaming music to an external bluetooth receiver the MP3 playback is flawless. It sounds fantastic. I've tried Windows Media Player, PocketMusic, and PocketPlayer and they all work just great.
However, when I turn on my handsfree headset (which is a separate device from my A2DP receiver) and allow it to connect to my TyTN II, extreme stuttering immediately occurs through the A2DP music stream. When I shut off my handsfree headset the stuttering stops and the music stream returns to its usual fantastic sound. The problem can be replicated also by leaving the handsfree headset powered ON and simply enabling handsfree service on the HTC TyTN II to cause the stuttering to begin. The stuttering stops immediately when handsfree service is subsequently disabled.
Anyone else out their experience this? Any suggestions? For the time being I have to resort to disabling handsfree when streaming music to my A2DP bluetooth receiver.
Skipping/Cutting out/Speeding Up/Slowing down
Not much to add other than 'Me Too!' and thanks for tracking this down since i thought i was going nuts since I've had a couple of times where i thought i had it resolved only for it to crop up again.
Are you also experiencing your A2DP audio speeding up and slowing down along with the audio cutting out? since to me that is the most bizarre of all of the audio freakery going on.
I found my Logitech handsfree less likely to cause cut outs when on than my Jawbone does. but neither were trouble free.
Just an update for those that may experience the same problem as me. I've noticed that sometimes I have perfect audio even though I am connected to my handsfree car system while streaming music via A2DP. So this leads me to believe that bitpool settings and such are not the issue...since the perfect audio can occur with the default settings. I have also heard in other threads that flashing a new radio may help...but haven't gone to that measure yet.
What I have been able to determine is that this horrible skipping/stuttering occurs when my phone is changing cell phone towers.
That is, if
1) Streaming audio over bluetooth via A2DP
AND
2) Tytn II also connected to a handsfree device
then A2DP skips horribly when the phone needs to switch cell towers.
I have confirmed this by using the program PhoneAlarm to log the cell phone towers my phone is connected to. My A2DP stuttering/skipping problem coincides with every change in cell phone tower.
Now having said all this there is still one other factor that plays into it that I haven't quite figured out. If I soft reset my device and then immediately connect to my car and A2DP stereo then I do not get the stuttering problem when changing cell phone towers. However if I spend the day using the device, active-syncing and such at work, then on the drive home I will ALWAYS get the stuttering during every cell phone tower hand-over.
Frustrating. Anyway...hopefully I'll eventually figure out the last piece of the puzzle. I would rather not have to soft reset every time I get in my car just so that I can get good audio.

I do recall getting this behaviour when using Windows Media player...but I have started using the new Pocket Player and have since never experienced the audio slow down problem.
I found a work-around that works for me. It's posted here:

I seem to have related but a different problem with skipping.
I have both Sony and goldlantern BT headphones which i tried (stereo profile).
Both severely skip audio when located on the left side of my belt. Silly but the reception/skipping problems improves a GREAT deal when i move it to the right side. It works flawlessly inside of the building where i have no phone signal but outside -- it skips horribly, even worse after 6.1rom upgrade.
Can anyone confirm that the BT signal going through the body worsens skipping? If so, I assume the signal strength/BT/wireless channel may be at fault, not the tower switching as for me, it happens even when I stay stationary.
Any help is GREATLY APPRECIATED!
TILT - R2 VEGA WM6.1 CE OS 5.2.19209 (Build 19209.1.0.2) ROM
I think part of the problem can be the A2DP device as well. I had a pair ofr HT 820 older bluetooth headsets with A2DP that were skipping and annoying. I went out and bought some s9s and the problem went away. I figured just for a test I would try the HT820 out again, still skipping. So for me it was not the phone but the A2DP device.

i thought that too but i have two different headsets from two different manufacturers, both are skipping the same...
A2DP requires a lot of the bandwidth Bluetooth can provide. Having a 2nd connection open simply exceeds what the Bluetooth chip can handle, no surprise in that. If the BT headset keeps the connection open it's very likely to happen.

what do you mean by a SECOND CONNECTION?
i have 2 different headsets because i thought that i have a poor headset, but both work similarly bad, which makes me think it is the tilt, not the headphones. i do not have 2 connections, never has it and not even sure if it is possible....
Lowering of bitrate did not help at all.....
Anyone have experienced these problems? anyone is using BT headset besides motorola s9?
On mine it does it when it picks up a wi-fi hotspot. When I'm driving the wi-fi is on when the screen is and whenever I pass a hot spot it drops out. Turning the wi-fi off solved it. Don't know if it does it with cell towers.

The thread was initially about skipping when BOTH an A2DP stereo headset AND a BT handsfree were connected at the same time, as the title shows. I was commenting on that.
Other than this, when I want to listen to music I can leave the Kaiser in my room and walk around in my entire flat with the headphones on without skipping (around 10-15m straight line, with some walls).
However, Wifi must not be active and communicating, otherwise either / both of them will drop. If I'm using Wifi and start streaming audio via A2DP, the wifi will slow down a lot and sometimes disconnect. In the same way if Wifi is communicating the audio will skip. If both of them are active but one is idle everything's fine. But that's also normal as both share the same frequencies and will step on each other. When usage is low it's not noticeable but when both are using a lot of bandwidth then they will disturb each other.
The cell radio doesn't seem to cause any problems for me.
I've noticed whilst gaming on the train using my HD7, I sometimes get interference in my headphones. It sounds like mobile static (dit dit-dit-dit etc).
Does this happen on all HD7's (maybe when reception is fluctuating)? I would be very interested to hear whether this happens (or not) from other HD7 owners. Thanks!
Any long conductor is susceptible to radio-frequency interference. In fact, headphone cables are so susceptible to it that your phone uses the cable as an aerial for FM radio reception!
Personally I use bluetooth headphones so don't get the problem. It does mean I can't use the FM Radio function but to be honest I can't say I miss it. On the plus side, I get hands-free calling all the time.
I have that same problem with my speakers whenever im getting a call or text on any phone that is on my table my speakers start to make noise 2-3 seconds before the phone starts ringing.
but ive never had that problem with headphones.

Whenever im using my Bluetooth headphones and pass through a scanner like the ones at libraries or airports my headphones start to make a high frequency noise.
I just got my HD7 as a replacement for my Venue Pro and am hearing the interference in my headphones that I've never had on any other phone.
It sounds like what my computer speakers would sound like when I had Nextel and a call would be coming in. I only notice this between songs.
Finally decided to ditch the iPod and use my Note II for all my music, podcasts, etc. I hate plugging/unplugging my phone every time I get in the car, I always left my iPod just plugged in and connected. My '07 Mazda 5 is old and cheap enough it doesn't have bluetooth. I looked all over for something that will basically take my Bluetooth A2DP stream and plug it into my AUX input of my stereo. I didn't feel like investing the time and money to replace the stereo in my car. After doing a lot of looking I picked up one of these, a GOgroove FlexSMART X2 Wireless In-Car Bluetooth FM Transmitter. I picked this particular unit because it has both Aux in and out for me to connected it directly to my stereo via the AUX input.
http://www.amazon.com/FlexSMART-Tra...&qid=1357759073&sr=1-1&keywords=car+bluetooth
I'm not surprised I liked the unit, the unit pairs fast, works great, does exactly what I want it too and all of the reviews were extremly positive. What I am surprised at is the FM modulator works better than the AUX input into my car. Volume level is better with the FM modulator, there is a slight bit of ground loop noise with the Aux input while the FM modulator is completely clear with better sound. I am stunned how well the FM modulator works because I've had nothing but negative things to say about FM modulators in the past. It has a feature where you hold down a button and it scans all of the channels and tunes itself to the clearest channel. That feature works awesome. I have a ~45 mile one way drive to work, and it was crystal clear the whole way.
great for no Bluetooth cars
One day I noticed a friend was streaming audio and using waze (gps) at the same time in his older car with no bluetooth. At the time I was researching options like a Parrot or an integrated in car upgrade kit and found one of these to be much more affordable. They have another model the SMARTmini which I think is newer but has a shorter arm so depending where your cig lighter is this may make a difference on what model to purchase. Grabbed one last year for an older SUV with no bluetooth and works really well. Happy to see this posted!
I have a JVC stereo in my smart fortwo. Great one and cheap. It has bluetooth for streaming and talking with it's microphone. Plus usb, plus aux. All in one.

This is what I use. Plugs into the lighter and is able to charge your phone at the same time. My Rogue has an AUX input so I plug the other end in and it auto-connects when I turn on the car.
Works great
I want to buy the HTC stereoclip, it uses a lossless APT-X codec, which if your device happens to support it (The NII does!) you get losslesss audio over bluetooth! Pricey, and requires being plugged in all the time when the battery dies, but I still want it!

Hello and thanks for this, does this take my cell phone A2DB intake and give line out to my auxiliary in? I do not want to use the FM function because it usually does not work well in my over populated area.
Ok, I've found this on you tube the go groove smart mini does have a line out jack

Here's a screenshot
My moto s705 soundpilot bt uses regular 3.5mm earbuds, so I got a cable from radio shack with male ends, plug from the bt to the aux input, streaming music, PLUS I can clip the bt on the visor and talk on the phone through the car stereo.
I've ended up buying this one http://www.amazon.com/SMARTmini-Bluetooth-Hands-Free-Streaming-Smartphones/dp/B008XMV05G/ref=cm_cr_pr_product_top
I made this decision as it appeared the smallest of the whole bunch.

I use a Belkin B46 hockey puck with inverter for power which use aux jack all hidden in the arm rest. Set it up to auto connect and kick off pandoea when conndcted. This way I get in my car and music starts playing. Cant stand the quality over FM.

Works very well with all devices, good choice for cars without AUX input. it streams music and handle calls all in one =], I love it!
I've never had good luck with these FM transmitters. For around $70 you can just replace your receiver with a Bluetooth enabled one.
I just got my device, and immediatly the first annoyance popped up. I started listening to music through my JayBird BlueBuds X headset, and the audio just stops going to the headset at random times. If I activate the voice dialer and cancel, it will resume for another 2 - 10 minutes before the audio cuts out again. Has anyone had any similar issue?
I am using Google Music only.
Can you see if your buds have a software available. I using 4 Bluetooth devices no issue. My Bose sound link did but after upgrade issue was gone.
BAD ASS NOTE 4
No issues with my bluebud x's like that. Used them for 3 hours straight the other day doing yard work. Try re-pairing or maybe you have some battery management tool stopping bluetooth?
Weird... Its only happebeing with my blue buds. Big Jambox and car Bluetooth don't have the issue.
I'm experiencing the same thing with the same headphones. Except the issue occurs with all of my bluetooth devices.
It is hands down the most unacceptably annoying feature that I can't believe comes bundled with an $800 device.
Anyway in this thread a member suggested turning off S-Health, which kinda sucks. I just did it a few hours ago so I can't verify whether it works or not yet.

so, that should tell you its the headphones, NOT the phones' issue
I have my Galaxy Note 8 hooked up to my Pioneer NEX4200 headunit in my car. When I'm streaming music/youtube, there's a sound kind of like the old mechanical noise from a cassette player that is quiet but audible. I do not get the sound when streaming music when the phone is hooked up via AndroidAuto. I also, occasionally, get a quiet high pitched tone (almost like slight tinnitus) when connected via normal BT. I have yet to test the phone with other bluetooth sources, but I'm wondering if anyone else has experienced this.
Dunno , but when my wife calls me using BT from her car, I hear screeching type noises in her voice, almost like compression.

My phone calls are all good, it's just streaming music.
I have several bt devices, and I have observed that with two, the noise is somewhat choppy, with another, sounds crackling, I use bt since my sonyericsson k700i, around 12 years ago, but, I started to note issues with bt starting with my note 3 onwards, I think that the evolution of bt has somewhat screwed backwards compatibility
