Hey guys, I was wondering whether anyone here knows of a car radio with bluetooth technology (there are many of those) but that supports not only phone use, but can connect and play lets say the mp3 collection from the prophet? I know this can be solved with cables or fm transmitters, but what about this (to me!) easiest and best way?

The Sony seems sweeeet!
The Sony seems sweeeet! Need to get me one of those when they're released.
Is it possible to use the wizard for a fm radio? I have read some diff. threads but haven't been able to come up with a answer about the wizard. Any help would be great.
Thank You, Great site I've learned alot !
No it's not
(removed the answer)
fm radio are analog signals based around 87.5 to 108.0 MHz
gprs/edge/umts are digital signals based around 900Mhz -> 2Ghz
options are to get a SDIO fm radio card
or get a wired headset with radio integrated
Thank You for the great reply Rudegar. Any suggestions on were to find?
DOnt some of the newer HTC phones have fm radios?
yeah they use an extre chip on the pcb to handle it i believe
some people believed the transiver was onchip on the newer Qualcomm
cpu's but as i dont show on their cpu blockdiagram i'd asume there
is a special chip on the pcb
it have nothing to do with the gsm radio
they dont even seem to share antenna
an with the new touch cruse it use the wired headset as antenne so it dont work
with bluetooth headset or using the pda speaker only :S
>an with the new touch cruse it use the wired headset as antenne so it dont work

Like with most/all fm enabled phones...
surely fm radio and better camera are the only thing wizard is missing in my oppinion

Have the HTC HD2 Leo (iphone 3gs convert (well nearly))
UK generic using on O2
Manilla: 2.5
rom: 1.48
radio version: 2.05
Hi i'd be grateful if anyone could answer one or both of my Q's, thanks:
1. Home screen tabs
Question: can programs be added to the home screen tabs.
I wanted to know if it was possible to extend the number of home screen tabs to the ones that already exist - home, mail, messages, internet, calender, [my program] etc. I'm aware that these can be personalised and removed but dont know how to add to them. Is this possible? Is there a reg tweak, cab to enable this. Couldnt find any so far. Already using the kindly provided tweak from Vovichek_Jamrecords to enable 16 quick links but wanted to add extra home screen tabs.
2. FM transmitter
Question: Does the HTC HD 2 Leo have the ability to transmit fm signals. Does it have a transmitter ability.
I wanted to be able to send music to my car radio without the use of a 3rd party bolt on fm transmitter. I am unable to use bluetooth and have no other way to connect to stereo. I dont want to replace it. Thanks.
The HD2 Leo has the ability to receive fm radio (via headphones) obvioulsy and wondered if its chip can be enabled to transmit. Is there an app, tweak available. Or is it a hardware question meaning the phone simply cant do it. If so can anyone suggest a bolt on micro usb powered fm transmitter. I have a bolt on transmitter for the iphone and wondered if equivalent could be available for the HTC
Thanks. Seb.
Note:
I have had the the Leo for a few weeks now. The main attraction is its great screen and openess to tweaks etc (despite apples jailbreak community). Being v new to the windows mob platform I'm struggling a little but I am liking it. There are many things that i am missing about the iphones OS (its much better suited for the simpleton). Its OS just seems much smoother and rounded. I'm sure everyone is aware of WM6.5 deficiencies. Apps just seem much more tailored to the apple. Well I guess Apple control the hardware and software etc and so is to be expected. Will keep perservering with the HTC however. If it just had a front facing camera (not that the apple does) then that would have clenched it. Also keyboard - no matter what cabs,tweaks i try its just not as good as the iphone. I hope WM7 that i hear is coming will be that much better. There's plenty of info about the phones on this forum and others and so wont get into the iphone v htc debate. However, comparison is unavoidable!
There is no answer?
I want to use FM Transmitter on HD2.
The HD2 does not have an FM transmitter.
You could try the Motorola T505 that takes a Bluetooth A2DP stereo signal from the phone and acts as a BT Handsfree, but it also retransmits the music as an FM signal.
Answer to question 1 http://forum.xda-developers.com/showthread.php?t=583638 (22)
Answer to question 2: NO
you can buy fm transmitters that take the output from your 3.5 stereo socket dirt cheap nowadays.I have seen them for a tenner on my local market though I would be a little wary of the signalquality. this has the added benefit of working with anything with a standard earphone output.I have never seen a micro usb transmitter.
Please forgive me/move thread if this is the inappropriate forum. I couldn't decide for 10 minutes, so I decided to go with the dev forum.
The FM radio: Is it going to be impossible to get it working on the N1? From what I understand the current state of play, devs have got the app working, it scans and finds stations, but it's as though the audio lines are physically not connected up (is this accurate?).
Could it be a limitation of the Alpha status of the Desire ROM being examined?
i think it is radio's fault
if google give us a new radio with fm and maybe some extra mb ram it will work just fine

I'm pretty sure the N1 doesn't have an FM receiver in it.
And if you don't have the hardware, you don't have the hardware. Software can't magically make up for it.
It'd be like trying to get an FM signal out of a toaster.

It has the hardware...there is a Gizmodo (think it was them) teardown of N1. Discusses the FM capabilities. Also...Desire and N1 have same hardware on the inside (different trackball feature and buttons..but the same). There are posts around the forums confirming this by Modaco and some others.

The Nexus One features a Broadcom BCM4329 chipset with "IEEE 802.11 a/b/g/n system (MAC/baseband/radio) with Bluetooth® 2.1 + EDR (Enhanced Data Rate), and FM radio receiver and transmitter" (according to Broadcom's product page).
It may not be fully connected up, or it may just be a software issue (hence my asking in this thread) but the hardware is in there.

What we need is the Desire's completed ROM, and might need it's headphone with built in FM receiver as well. When yo utry and open the FM radio app, it asks you to insert headphones with a FM receiver... well, some have tried and get it to lock on stations, but no sound. Which seems to mean it is a lack of a completed ROM/app, not hardware.
It's possible we may never get this feature working. Not a big deal to me, though. Pandora works fine!

The headphones don't have the receiver in it. it simply uses the headphone cable as an Antenna just like the iPod Nano's built in radio.

any headphone can act as radio antenna...at least it works in nokia symbian phone. no need to use specific headphone.

Yes and no... if the chip set itself has FM, which the Nexus seems to have, then this is true. But for many "dumb" phones it is the head set itself. This is why I said may need the Desires headphones, and then went on to say it seems more like a lack of a completed ROM/app, since you can tune, just no sound.

Pandora is way better" there is one show in particular here in town that I can only either stream over the internet (requires flash) or listen on the radio that would be kickass if I could catch over FM on my phone. If i want to listen to music then FM radio is definitely the last place I'll go lookin....

I'm not sure I would use the FM radio every day, sure, but it's an important feature nonetheless. For fast local news with minimal battery drain there's nothing like having a radio handy.
Many of the on-line radio services are great/better, but require you to use precious data bandwidth, and I resent that. I don't like the idea of my phone being a gateway for the phone company to make more money off me. I spend most of my life within wifi hotspots, and use the cellular web service as little as possible. Apps, audio books, and presynched RSS feeds can pass the remaining time.
For example, I was shopping for an iPhone in the final months of '09, and the cell companies all offered to "unlock" the GPS function of the iPhone "for three months for free". Hang on, I asked, the iPhone has its own GPS, so why a) would I need them to "unlock" the capability and b) I would have to pay for my own GPS after the first three months? I learned that, while the GPS coordinates come for free, the maps are the domain of the cell company. Screw that.
One of the best features of the N1 is the built-in Google maps, and while I might be willing to pay one-time for TomTom maps or software (the best GPS OS imho) but pay every month forever, no way.
I was trying to do a little research in to if I could get the FM transmitter/reciever to work or if it would be even possible. A little google searching around I found this. And the person who had been doing the most work on that part of android was an actual broadcom employee. So I sent him a quick, polite email asking him about FM support in the Nexus one. It is as follows:
"Mr. Harte,
I noticed your commits here. Will Broadcom provide support/drivers for the FM transmitter/receiver in the Nexus One and other Android devices?
Sincerely,
Will"
And his surprisingly helpful and quick response:
"Hello,
The FM receiver is supported in the HTC Incredible and HTC EVO 4G. I’m not sure if the Nexus One hardware supports FM. The 4329 chip has FM, but I don’t know if the external components required for the FM Antenna are populated on the board. I believe there is also some work needed in the kernel to enable the audio path for FM, but if/when HTC open-sources the kernel for the EVO or Incredible, this should be evident. Also, the EVO and Incredible use the Broadcom Bluetooth stack, while the Nexus One uses BlueZ. I don’t think there is any support in BlueZ for FM. I have no idea about FM Transmit, but I would highly doubt it is possible to get that to work…
-Howard"
That makes me sad but at least now I know. Hopefully though this will provide some light to any crafty developers interested tinkering with this.
Shorthand.
Even if the hardware says fm/transmit/receive, we would have to solder, replace the bluetooth stack, and possibly replace the chip firmware to get it to work.
Short, short hand.. NO FM on nexus one.
No really, somehow he neglected to mention the sister Desire.
Regarding the antenna portion, it's been proven that the nexus can find stations. . .just not output any sound from them.

I do remember reading about that. Can you find the source? If thats true, then we know the only problem is the stack.

Check the notes from Modaco's Desire ROM port. I think it's there. But since FM radio is analog, there may be a lot more to it than a stack.

Yup, his bluetooth doesn't work because he is using the Nexus One kernel. Well, we now know what part of the kernel isn't allowing the bluetooth to work; Bluez vs the Broadcom Stack. I don't know the legal implications of using it, but it seems like it would be possible.

Patently FALSE.
All we need is a kernel with FM support and the FM driver. Receive is definitely possible.
I do believe however that the power amplifier chips for transmitting are absent, so that won't be a possibility.

Getting an analog tuner that isn't connected to anything to tune is not much help. I don't care what software you write, if there is no output to be captured, it's not going to happen. It's like a cable box with no television connection. It tunes just fine. If the rest of the connecting hardware is there, then there's a shot. But Google has never said there would be FM in the Nexus One at any point. I am less than optimistic.

That still has not been determined.
or you can go to your favorite radio station's website and click on "listen in" or whatever and now your listening to FM on your phone. =D
or maybe not, thats how it works on my pc..
i dont understand what the bluetooth has anything to do with this? why does it matter the blueZ vs broadcom bluetooth hardware? it sounds like the fm radio portion is there and can even pick up stations with an antenna, just routing the audio. but that doesnt need to happen thru bluetooh, it could happen through the headset or loudspeaker.

For the most part yes (esp. with those of us with froyo and flas ). But what made me start searching for this was a tornado that past by me by only a few miles. I luckily was in the car and able to tune in to a station broadcasting the Emergency Broadcasting Systems's message, but I thought it would be nice to be able to do that on my phone.

Integrated circuits perform multiple functions. That broadcom chip could do a lot more than blue tooth. FM is analog. If all you have is the tuner and there is no connecting hardware, then yeah, you receive a signal, but it's going nowhere. If you can't capture the output, you can't use it. Do we know if the FM radio signal in the Desire is ever digitized? It could work like a regular FM radio and the digital/software part is for tuning purposes only and radio itself is analog. I read somewhere is that the HTC FM radios require wired headset use - and don't play back through blue tooth. Irony there, I think. Speculation is that is because they are used for an antenna, but I think it could also be that it's because it's an analog output. I am guessing the N1 is missing all the required circuits - except the tuner.

This is true of the Touch Pro hardware at least. The FM Radio wouldn't function with out the headphones plugged in. It used the headphone wire as the antenna.
there is a great thread going in the nexus development area where some people are trying to write the kernel so that the sound has an output. It sounds like they are making great progress maybe anyone reading this thread who has some technical skills can help. I believe they too have been able to tune the phone to a station but not output the sound yet.
It seems to me we need definitive answers to the following 2 questions from HTC / Google ...
Q1. Does the nexus one have the necessary hardware and interconnections for FM radio reception and output through either the speaker or headphones. YES/NO?
Q2. Does the nexus one have the necessary hardware and interconnections for FM radio transmission of any type (music / voice). YES/NO?
If both answers are a definitive NO, we can move on. If there is a YES then the clever people here, who make the magic happen, have some hope of success.
Does anyone know the correct ppl at HTC / Google to ask these questions of?
I don’t have anything to add but would like to encourage you guys in your endeavour to get FM radio working on the N1 and also point you too or remind you what androidpolice reported at Google I/O
If this is true then perhaps all the building blocks are in place.

Or maybe we just need to think and use the info that we have in other threads on the subject. But I'll repeat things written in another thread, by myself and other guys:
Q1. Broadcom chip brief (the best doc available for it on the net) clearly shows the radio having no separate connections but using BT's high speed UART and I2C. The interconnects are the same, and since Paul's Desire port has radio control working - that means I2C is working too, so the answer is YES.
Q2. The stated output power of the chip is good enough for short-range transmission w/o a dedicated antenna, using headphone cord. The control and data are given in the same way as in Q1. So, the answer is YES again, but with more trouble - while there is a working device utilizing FM receiver functionality, which can at least theoretically be ported completely using its source, there is no device with FM transmitter, which means - if someone wants to use transmitter, that someone needs to acquire specific Broadcom documents for the chip.
So I guess the thread can be laid to rest, and anyone that can really help - for example, to go over Desire source and figure out the correct setting for QSD UART to receive FM audio and the procedures to stream it to the speaker - are welcome to head over to Dev section.
