Guys,
I have found another settings
Go to Program File -> DopodScv, you can find the "GPSRecorder.exe" file
The program runs under Traditional Chinese character, you may try it out
surely this only works if you have a dopod touch dual?
as your going into dopod scv
Yeah, have it but can't use . Is this another sign that HTC dual has GPS?
It seems like HTC has disabled Wifi, GPS & FM Radio on Touch Dual
Anyway, i'm selling my Touch Dual within these few days... Good luck to everyone
I wish that my finding helps you guys in investigating the Touch Dual, especially the Wifi & GPS
GPS: Why do we need it IN the dual - I much prefer the battery life dividends that my Bluenext GPS receiver brings me. 25+ hrs (quoted) continuous... if it was in the Touch surely it'd be a real battery drain?
WiFi is different though. I respect it's also a battery drain, but I wouldn't have minded that for the occasional use. There's no bluetooth wifi adaptors out there?
Just my take

Perfect, finally the MicroSD version. Problem is that there is no extra space left. I now use a 2Gb card for music and TomTom maps...
Interesting, but wonder how well that would work without an antenna...
As any way Itis not important!!?

Hi there Guys i know you have all stressed that there is no antenna for the GPS in the touch dual but i would just like to bring to attention one note, in the uk T-mobile happen to offer the touch dual , with a preinstalled navigation software called Copilot live7 which usess the intetrnal GPS, i have also visited the copilot website and they have confirmed compatability with HTC touch dual. so so so anyone got anything to that?
It's true, sort of
Built-in sat nav
With the CoPilot® version of the T-Mobile Touch Plus, you get live satellite navigation with on-screen and audible turn-by-turn directions. CoPilot� is powerful satellite navigation software for your mobile which performs just as well as a dedicated or in-dash navigation system. When your mobile has sat nav you save on two counts - you won't have to pay for a separate device plus you'll save yourself from ever getting lost again.

Hello,
did somebody find driver sources for the FM transmitter in the BCM4330?
"Other things of note about the BCM4330 is that support for Android and Windows Phone is built right in, so this chip is just plug and play"
Hmm, maybe looking for other phones that use the fm transmitter part?
what do you need the source for?
Maybe we could use it for a sound transmission (music) to the car radio.
Yeah if any dev would find a way to activate it that would be great awesome

There is no FM radio on Razr...
But you can buy for exemple Sony MW600 device (it's a stereo bluetooth headset with integrated FM radio) for 40€... It's works fine with Razr...

Perhaps they are saving it for ICS?
I mean, why bother to make a gingerbread app for it when they have to do it again for ICS?
But then again, it is sloppy work... same with that NFC device they stuck in it which doesn't work.
It's not as if it's something new; back in the day, I bought two Motorola A925s with a really nice AGPS installed which turned out to be faulty on both (one never got fix, the other one was just dead) and was probably never meant to be used for something else than a marketing gimmick...

It's still unconfirmed, last I checked. Pretty sure the RAZR's WiFi/GPS/BT chip does have FM capabilities, and is just lacking driver support. See: http://forum.xda-developers.com/showthread.php?p=20133613 for further discussion on the chipset.

The Chipworks teardowns clearly show both the Droid 3 and RAZR have the WL1285C chip, and the Droid 3 supports FM. Of course, the Droid 3's chip is labelled 2-WL1285C-13M1HH3, and the RAZR's is labelled WL1285C-19M0JZ3, so they may well be physically different revisions, it's certainly possible the RAZR lacks FM support entirely. I really don't think the information we have is conclusive enough to say "There is no FM radio unit in the hardware at all", though.
Don't know that this is what you're looking for but I use the app TuneIn Radio. Yeah, I know, it's internet-based.
However, with my Droid X I tried several "radio apps" but couldn't pull in a 100-watt FM station I listen to. Nothing worked with this ONE single station.
Now on the Razr, I've found the TuneIn Radio and it's all I need for my local station.
For those with Maxx battery tunein radio wouldn't hurt but a regular razr would die quickly without fm radio support.When we have unlocked bootloader, we can have the fm radio feature unlocked,too.
Tried a lot of radio apk, all failed to deliver signal and sound.
FM radio
When I bought my XT910 it comes with android 2.3.5 and FM radio works! I cleary remember my hard dilemma to install ICS with RSDlite or not. I knew that will lose FM and accept this. Now, I wonder is this was smart choice?
So, XT910 definitely have FM radio capability in hardware, just lack new drivers to support this. Bad choice from Moto to not implement this in android 4+
I just got an S3 and I'd like to ask if it is possible to listen to FM radio over Bluetooth.
i connect the standard headphones to enable the FM radio and the only option is to switch output between the headphones and the loud speaker.
I've seen cheap chinese android phones doing that, there should be a way.
Any help would be greatly appreciated, help me avoid selling my new toy
Sorry to say but it won't work. The reason (as the app itself already accurately describes in the error message) is that your headphone's cables are used as an antenna for the phone's FM receiver.
FM antenna's are actually quite big (at least compared to other antennas) even when using the so-called fractal design because they use a very slow (roughly 80 - 110 MHz, compared to e.g. WIFI's 2400MHz) frequency. To save space, Samsung moves them to the hedphones on all mobile phones I know of.
I don't know if it still works on S3 (never tried) but on the S1, if the station is broadcasting with enough signal strength, you could cut off the plug of old broken headphones and plug it into the phone to use the radio.
Afaik Spirit FM (now paid in all versions) can override the requirement but you'll need to press your finger to the jack so you can receive anything... pointless.
Alternatively you could use an app for internet radio such as TuneIn; most radio stations (at least all around here) provide web-streams for on-the-go radio listening. However you should make sure you got a decent internet flatrate, I managed to chew through nearly 4GB just with music streaming this month.
Most countries seem to have abolished mobile data flatrates.

The OP understands that the phone needs the cord to act as an antenna. I think what they simply want to know is if the phone can then route the sound to the bluetooth device instead of through the speakerphone or the headphones.
Sent from my MB860 using XDA
d4fseeker I understand that the headphones should be connected since they serve as fm antenna. What i want is to listen to fm stations through bluetooth while the headphones are connected as bigb25 says.
TuneIn is not a solution for me since some stations I want are not available and cause I am a hiker internet is not always available where I go.
Maybe there is a fix or a different radio fm app?
OK quick test... plugged in 3.5mm - 3.5mm jack lead into headphone socket to act as the FM antenna and started the radio, selected sound to speaker and all worked fine. switched on Bluetooth headset no sound in headset, switched off sound to speakers still couldn't hear anything. Unplugged patch lead (this ends radio anyway) played an mp3from music player and sound returned to BT headset.
So unfortunately the answer is no you can't, as soon as you plug the anything into the headphone jack it cuts out the sound to any other device.
This may well be a mechanical switch within the headphone socket and so unlikely that there's a get around in a custom rom....but then I know nothing about roms

The latest Free version of Spirit can always be found at the top of post 1 of my Q&A thread. See my sig.
My cheapest ($80) test phone gets good audio AND RDS with no antenna. Ironically it's the best of 12 operational test phones I have. It's a Samsung GT-i5500 with the great, sensitive new Broadcom 4330/20780 family of chips.
But yeah, my Galaxy S and S2 don't do very well with no antenna. My Galaxy Note does better. Haven't heard from anyone with an S3 yet. They all have the Si4709 FM chip, which has positives and negatives. Internal circuitry etc. makes a difference too.
And I can thank the very positive sales response I've had from S2 and Note owners for being able to buy these expensive devices for testing. I'll do everything I can to make Spirit run well on S3 and hope to buy one soon.
I have yet to find a phone that does FM over BT, except for a strange very low quality mode I have working on some BCM 4325 based devices.
If the FM can be done in the digital domain, instead of the more common analog, then in theory it should be possible to do FM over BT.
But then again, in theory the Galaxy S and S2 hardware are capable of FM record (digital). Yet the audio libraries don't seem to support it, and I think it'd be a major/infeasible job to hack the libraries for it.
The Note and I think the S3 can do FM record with stock audio libraries. So I think FM over BT on these devices is feasible, at least with stock ROMs and/or using stock libraries.
But on non-stock ROMs like CM9, the Note seems incapable of FM record.
Basically, if the stock ROM and stock FM app don't support FM over BT, then I think it's not EASILY possible.
If it could be made to work, there's no reason why a phone couldn't have a wired earphone plugged in at the same time that FM goes over BT. This might "confuse" the audio system though, which usually sends audio over a wired headset if one is plugged.
Then again, it's also possible to have a plug that's partly inserted (or maybe even wired creatively). Enough for antenna but not enough to push audio through the wired headset.
Thanks mikereidis.
I tried the free version, it plays only when the headphones are connected.
Do you think you could look at the possibility to send output to bluetooth?

That's very interesting; thanks for the info.
There are a variety of relatively inexpensive Chinese devices that have unique qualities, such as FM on an Android tablet, or digital TV tuner, or FM transmit I think.
But these devices are not widely available, or popular I think, in most Western countries. Information, source code and custom ROMs can be difficult to impossible to find.
As for Android: the audio systems can be kind of a big complicated mess. I don't think I've ever seen a single phone with an audio balance setting, among other things. But at least some Androids have "over the air" FM, whereas iPhone's have never had FM, despite years of rumors.

Kind of a drag to have a dongle hanging off though, in addition to the wired earphone for antenna.

I just ordered the apparent successor, the MW1 for $120 plus shipping the other day. It even has a music player built in, besides the FM and BT 3.0 support.
I need the A2DP headset because I think I'll be able to support FM over Bluetooth on some devices in the next few months, and I need something to test with.

The headphone jack has a part that senses when a headphone is inserted (the metal
in the headphone plug shorts it. It seems like you could make a plug that connects
to the metal of the ground pin (for the radio antenna) but isn't "inserted" so the phone
won't disable using BT.

Update 27/07 - did not improve the radio enough to recommend this modification/change.
Apparently the TEF6686 module has better performance than the TDA7786 - e.g. 7786 poor sensitivity, selectivity, multipath issues etc. My JY TDA7768 is terrible, even with an RF amp, so to find out if the TEF is any better, thought I would try and investigated swapping tuner modules. Reviewing the GS board I have as a spare part against my JY, I identified the modules are pin-for-pin compatible.
Sucessfully swapped the Radio module from a donor GS board containing a TEF6686 Module into my JY board originally containing a TDA7786. The GS board was quite difficult to unsolder the module, perhaps due to leadfree solder, fortunately the JY board was easy, the desolder wick readily desoldering the module.
As for results, I have bench tested and RDS, tuning, audio etc is OK, I am yet to test in the vehicle. Will update this thread with results.
See attached images. Note that the JY case had additional mounts that over time might short out against the non-ground PCB tracks, resulting in complete failure of the unit!
Welcoming any questions.
Did the reception really improved?? And RDS AF fuction is working well with malaysyk V3 firmware?

Hi,
The tef6686 appears marginally better, is more sensitive and appears to handle multipath better. Im not sure if I would call it out as a worthy upgrade just yet - need more time.
wonder if it can be bought on its own.. seems like just the chip itself which is surfaced mounted on the riser card as pictured above.. so this would prove difficult to install

could be something else in the implementation, not just the chip itself.
i have 2 boxes, one with 7786, the other with 6686 and the difference in reception is worlds apart. I mean even with the powered antenna not connected to 12V, i had no hiss on any station received.
7786 with powered antenna is just fine, don't get me wrong, but 6686 is better.

I had thought about that but there's no difference in implementation I can see after comparing from schematic. Perhaps I had a 'good' 7786.
- MCU is latest HA
- Both modules are digitally controlled by MCU/i2c bus.
- same supply
- latest HA android 6.
There's really not much to it, 5volts, antenna connection, i2c comms and audio out. I get multipath noise/crackles from stations between 99 and 102mhz. Same between both tda and TEF.
Can you clarify what you mean by 'better'.
Hi!
Maybe there are some differences in the Radio Software used in the different HU. The Chip is controlled by I2C and it seems to be possible to activate or change some behavior of FM Reception through some commands.
Is it maybe possible to extract the radio Software from the good HU so we can try it out on different devices (with TEF 6686).
It would be really nice if it would be possible to control some of the possible configuration of the chip manually...

No differences in android and same MCU, MCU controls radio module via I2c. The "upgrade " has no discernable difference.
Any more details? I need a more sensitive tuner. I have a full power mast but my car is all SMC so the radio needs all the help it can get.

Sure - there are two different tuner modules and neither of them are 'better'. I suspect its hit and miss in the production of either modules.
If you have a proper external antenna, which is properly connected, there's nothing you can do apart from using internet streams or DAB if available for best quality.
thanks, do you know if these unit have the 7786 or the 7786M IC?

Are you sure ? Cos on MTCB/C units the AF doesnt work and the PTY is plain wrong (I have an MTCD unit now but I havent tested the radio yet, its still on the bench), but someone (deffo Italian I remember that) made some changes and got PTY to work correctly and I thought he did it by modding the app ratehr than anything on the MCU side. Sadly I cant remember exactly what thread it was in, or who it was.

Unfortunately the only way to tell on MTCD untis is to open it up, unlike the MTCB/C units where you can select the tuner type in facory settings, which is strange cos MTCD MCUs are much more powerful 32 but compared to MTCB/C's 8bit . . .
. . . or maybe there is a way ? - @marchnz's dmesg output mentions "6686" in the first post.
Hi,
Can someone help with radio module pins schematic for XD-6686AF-0. This is same radio module that @marchnz has swaped. I am forced to change main that is not pin to pin identical to TEF6686-TDQ-230V-86-TDQ-230V-86-R that I have from aliexpress.
Thank you
P.S.

I guess this is what I am looking for.
Leaving a tip for everyone looking for this schematic.
Thanks to @marchnz

Do you have a datasheet? Shouldnt be too hard to match up against schematic.

Radio module that comes from aliexpress has description on every pin.
Can be seen on the picture that is provided in this link.
I can make a new photo if someone needs clear image of this module.
