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.
Hey guys,
I was just thinking about that nasty little problem with cyanogenmod and our legends and since there was no meaningfull advencment, we could put some money on it. I think from 5 to 10€ for each doner would be enough or what do you think? Of course the developer has to give us an account to send the money to.
I would just like to use the FM radio and since it is working on desire for some time now, why not on legend.
So who is ready to do it?
would support that idea.
It is already stated waaaaaaaaaaayyyy before. The FM radio WILL NOT WORK on the Legend because of it's alien architecture. Don't ask me, I don't know ****. But if you're do want to make a donation then you can donate to Ali Ba which has been the sole reason CM is running on the Legend.
This is a good idea.

here on this link http://forum.cyanogenmod.com/topic/8260-fm-radio-support-for-legend/ ale baba himself says it is possible but that he hasn't got the time for it. So it is possible we just need someone who will do it. But first of all we need more people.
I'd consider doing development on this. I was wondering why there was no FM Radio app on CM7, LOL.
At the very least I can commit to finding all the info I can gather on this issue. I have no (satisfactory) employment at present and want to break into the Android specific field.
I have 14 years experience in embedded Linux development, including lots of low level kernel stuff. In a previous life (more decades ago than I dare admit) I did electronics engineering stuff, and I still love the low level nuts and bolts.
I'm pretty new to Android however, got my first cellphone (ever!) 17 days ago, first Android phone 15 days ago, and my Legend yesterday.
I think I can learn quick, I'm CM7 nightly, S-Off, new radio one day after getting it, LOL.
So my point is I, and this project, could use help in areas of Android specific knowledge.
Does anyone know if the normal FM radio app I've used before is proprietary Google code ?
Are there any generic FM radio apps that would work if standard drivers existed ?
My quick research on this is that only a driver might be needed. A V4L (video 4 linux) driver, which I have already had some experience with.
But there DOES seem to be a V4L driver already for Linux for the TI WL1273 chip apparently used in the Legend, and apparently a number of other phones. So in theory, this job might be as easy as integrating an already written driver in to the CM kernel, as a kernel module or 2. There MIGHT be some copyright issues with any chip firmware though.
Alas, some comments indicate using such a driver might interfere with Bluetooth functionality.
Interesting stuff about the 1273 chip is that it may support an FM transmitter, and it supposedly supports WiFi N. But who knows if needed hardware support might not be on the PCBs.

I've been reading that there IS an FM Radio app integrated into CM now. It comes from MIUI, a chinese group of some sort that also makes an Android ROM.
The app apparently uses /dev/radio* which is the standard V4L radio interface. I have these also on my Hauuppage PVR boards I used for HTPC before I went completely digital for movies, tv, etc.
So yes, what we need is integration of a driver into CM kernel, but coding may be needed to fix bluetooth driver interference etc. And of course who knows what else might be needed.
I'm reading that FM is much more important to those without data to stream. Not all of us live in wireless data dense cities and countries.
Would be interesting to see what frequency range can be received and maybe transmitted.
Would be MOST cool to stream from video camera to transmitter for local "pirate TV" type functionality, LOL. Actually can't imagine ATSC or even NTSC (or PAL etc.) encoding possible, but wireless streaming will do the job...

Thanks for joining in, great highly appreciated. If there is any time left it would be nice if you could look into the GPS problem with CM 7 it is currently not addressed.
Anyhow thanks for your participation and contribution.

So are you going to try and port it?? If you will and you'll succeded then you will be the legend in Legend community!

I can keep my eyes and ears open to GPS, but best to concentrate on one issue at a time.
What is the GPS issue ? I thought it didn't work on my phone after new ROM but within a few hours it was working OK for whatever reason. And now I see 2 metre accuracy compared to the minimum of 5 on my Optimus Chic.

I'll do whatever it takes.
The userspace FM Radio app shouldn't need any porting work AFAIK. It seems to already be in CM 6.1 ROMs for the Nexus One (any others?). So I'd guess installation would just need to be enabled for other phones.
The tricky part is getting a device driver working that creates a /dev/radio interface for the MUIU FM radio app to use. There IS already a Linux driver for the WL 1273 the Legend uses, but it might need some modifications to run on the Legend.
But there is some complicating factor regarding bluetooth drivers, so it may not be too straight forward. For initial testing at least the bluetooth drivers could be disabled.
What about HTC's kernel source. As I told in cyanogenmod forum the drivers should already be in HTC's kernel source. If the code is there it should be easy to put it into CM7 kernel and use HTC's FM Radio app. Or what do you think?

Yeh, thats the problem. GPS is working on some devices and on others not and nobody knows why. As a matter of fact when I'm running CM 6.1 its working great. Flashing CM 7 no change to get it working. As mentioned others are reporting the same issue with CM 7 on some its working on others not.

When I get tired of Google maps seeming to take forever to figure out my GPS location, I've downloaded and run the "GPS Test" and "GPS Status" apps. I did so and for some time the status color on one of those showed yellow, meaning no GPS fix, but power on.
Anyway sometime later it was working. One of those apps downloaded data to make cold starts work faster and that may have helped. A few things to try for anyone interested anyway.

The problem with running the HTC FM radio app on CM is that it, like many other HTC apps, uses the HTC framework with Sense UI. So CM can't run it, although stock or modded Sense ROMs should be able to.
IMO right now the MIUI app is the way to go, and it's open source so anyone can modify/fork it.
Yeah I think a /dev/radio is likely in HTC source, but it's possible it's something different and/or kind of proprietary.
The Chip manufacturer, TI, and their partners who make RF modules based on the chips, DO have android /dev/radio drivers. So they are definitely out there somewhere.
I think, as usual that "In Theory" this should be a simple matter, in reality there is usually some problems to solve. Otherwise we'd have FM already in CM.
A few pointers:
TI 1273 has a few interfaces for communication. One of them being a (standard) serial via bluetooth, the other one I2C.
HTC did not use I2C because they already had to use the serial interface for bluetooth and it's a lot cheaper that way (that's what all manufacturers do, by the way). The wl1273 driver in the Linux kernel does have support for the FM capabilities, but unfortunately via I2C only.
So basically we already have all the drivers we need in place (tiwlan_drv, sdio), no kernel stuff needed. What's missing is valid documentation about how to enable radio, route it to the headphones, seek/tune, etc.
You could reverse engineer /system/bin/btipsd, which does bluetooth and FM communication in original HTC releases.
Once you are able to control FM stuff (with bluetooth turned on) write a nice summary and I'll ask cyanogen how to implement it. Won't be that hard, given the fact that currently all supported devices use the serial interface via bluetooth.

Thanks ali ba ! Yes I know about cheap manus, I've worked for a few, LOL. Linux VOIP and security appliances mostly though.
By "The wl1273 driver in the Linux kernel" do you mean the TI provided W1273 driver in the CM7 ROM ? I had thought that driver was for WiFi only, or perhaps WiFi + Bluethooth. Or does my seeing an rfkill device mean FM radio is in there too ? Would it create a /dev/radio device ? There are some FM init BTS files that may enable FM.
My understanding is that the WL1273 WiFi driver in the mainline Linux kernel (not the Android kernel) is WiFi only. There's a guy from Nokia trying to get WL1273 FM radio only driver into main Linux kernel but not there yet. That driver will be separate from WiFi driver even though they may both have WL1273 in the name.
I've been finding some HCI commands usable with hcitool to do audio routing stuff at least. RevEng has been a specialty of mine, so I think if it can be done, I have a good chance.
Quickest route to a working FM radio on Legend is to find an existing app for another phone that works.
Phones with the WL1271/1273/1281/1283 chips include original Moto Droid, Droid 2, Droid X, Motorai, Nokia N800 (or N900?), N8 (?), B&N Nook Color.
There's a thread here on XDA about Droid 2 phones using the Droid X FM radio app with success. I tried that app but there seems to be some problem launching the fmradioserver.
I saw a logcat message that may indicate I need to "adb install" the APKs instead of just copying them to /system/app. I tried but got the error that indicates the UID does not match the signature. I guess that's not an issue on Droid 2 (or motorola phones in general?)
Does anyone know if/how to mod/repack an APK to avoid the UID signature issue ?
A few more of my findings for anyone interested. BTW should I or someone create a thread in the dev section at this point ?
As mentioned above a guy from Nokia is trying to get a V4L2/dev/radio driver for WL1273 into mainline Linux kernel. That driver could be integrated into our kernel, but it might take a bit of work. And as mentioned that driver is not in kernel yet and may have lots of changes still coming in the next several months at least.
But TI also has a driver, and it's meant for Android. I haven't been able to grab source code for that driver yet. I think TI driver references WL1283, the biggest baddest version with GPS too. But driver is supposed to work on all 4 variants, down to WL1271.
TI has a command line app for testing fm radio, I think called fmapp if memory serves. It's possible this test app could at least help with exploration.
Unlike the poor original Droid owners, we are lucky that we know our FM receive antenna is connected, since stock Legend has FM radio. But there seems to be a different pin for FM transmit so it's possible we will never be able to transmit FM more than a few inches. But Tx would just be a bonus, but a potentially wonderful bonus.
And, ya know, I'm not even sure if MIUI FM app works with /dev/radio. I was looking at some source and it seems to be hardcoded with Broadcom chip specific stuff.
Oh, and my understanding is that even if we ever managed to get Wireless N working (with a new or improved stack perhaps?), that it will likely kill batteries quickly enough to be effectively unusable. Would be interesting though.
MAJOR EDIT TO THIS POST AS NEW KNOWLEDGE HAS COME THROUGH. (BUT YOU MAY KILL THIS THREAD AND GO INTO THE I9305 forum and go into the I9305 Tear down thread)
The I9305 may or may not have hardware capability for FM radio, But the firmware software doesn't have it installed. The funny thing about this is even the Optus Customer service and technical support are not aware of this, they do beleive they are supposed to have the FM radio.
MOBICITY sells it and there specs show FM radio and I even asked there customer service again and made them triple check and they confirm it has it and I seen a youtube video of the White version but this is from UK and its definitely having the FM radio app. So Maybe some developers can get involved or maybe not, If there is a 3rd party app around that will work in place of the Fm radio app then if it can be posted it would be great thanks. EDIT: Mobicity Now changed and said Because they are coming from Hong Kong there wont be FM radio Installed as per hong Kong Laws. Specs have now been changed on there site a i told them it was false advertising lool
Edit: Apparent Proof that FM radio is in some I9305 >>> http://www.youtube.com/watch?v=VGICeramJxc Look @1:14 4th column 3rd row you see FM radio app- I also messaged the guy and he confirmed it working, Edit: User Said he heard static, Then after more people interrigated him, he seemed to have changed his waysss and said he thought static meant Silence I then questioned him aswell but I basically called B S . In electrical terms static means Hissing/white noise/ Scramble. etcc...... He then questioned me as to why he had it pre-installed on his I9305 ... Apparent I9305??? Is it even a I9305 in the video Or a changed Build.Prop to show different Model number I9305. Can be done in 10 seconds. Cause why would samsung put the Radio FM app in it and its not working. NOT 1 Confirmed I9305 has the FM radio app. Except for that guy. Hmmm..u get my point now.. Anyway After he questioned as to y he had radio I told him to question where he bought it anyways that is the last i heard of him.
More Edit : We have a 9305 Hardware teardown thread, and as we are not hardware minded we cannot confirm 100% yet. Although we do know we have the a broadcom Chipset with the capabilities of FM radio, but the problem there is it is not linked up. So really then we do have the hardware but its not plugged in. Just like the I9300 has The broadcom one which is not hooked up and the Silicon labs which is hooked up, Now i dont think we could locate the silicon labs chipset on the i9305 board from a few pictures show.
SO far there is no 100% proof of this radio so untill then , I say it does not have FM radio. Unless some that knows chips and fm chips please go into the teardown thread and advise us so we may solve this query
As I said I have only seen 1 with the FM radio that you-tube link above shows it and I also emailed the user and he confirmed it working but then after more thorough interrogating the user changed the meanings of his words loll. Anyway Kill this thread. Come into the I9305 arena and go into the (I9305 Teardown thread) if you want to discuss this topic
Thanks for your research man. Unfortunately I'm not 100% convinced since I can't see that the phone is i9305 in the video (only the screenshot below which could be from another phone :/). But, I hope it's true, we just need more evidence and help. Did the youtube guy tell you what firmware he was on?
So you mean the original firmware of i9305 doesn't support FM, so even rooted and use Spirit CANNOT use FM radio feature?

If the hardware is there, then what we need is a kernel driver. Flashing a custom kernel (and/or ROM) with the driver, along with root/SU access should be sufficient.
Hypothetically, a kernel driver could be loaded without a new kernel, but practically it's quite difficult to do. In theory one could also poke the I2C or whatever controller, but that too is not easy.

I watched some of the first hands on videos and saw the FM app, but no video I saw had somebody try it, that I can recall.
I was reading I think about the above person, and the story seems to be that they heard static and thus didn't really confirm full operation. They may have been in a bad reception area though.
Static is actually a good sign to some extent. It indicates the FM audio path is there and usable. And I think static is better than relative silence, which you might get when an antenna pin is grounded to disable all usefulness.
It's possible that a software controlled switch exists for the antenna connection, or a hardware jumper. It's also possible that US variants won't have the Silicon Labs chip installed, but other variants might.

What this means is that the Framework code is there for FM. If there's a chip and we can load a driver, then there's a good chance the Samsung GT-i9300 or GT-i7100 FM app would work.
But we're no closer to knowing if the FM chip is there. Here's the teardown thread in progress: http://forum.xda-developers.com/showthread.php?p=33275259
Hey Guys,
I just bought a brand new Kenworth W900, and it has android auto (or something mimicing it) built in... A panapacific dea600... the major problem is it super kludge... amongst being terribly locked down, i cannot connect to an ad hoc wifi thru my windows 10 laptop (that is tethered to my S6 with easy tether)... my tablet can connect to the ad hoc no problems, and my stereo can see the network but cannot connect to it for some reason (i REALLY need to update the trucks GPS maps, and have you tried to use a truck stops wifi? (like dial up))... id really just like access to the OS or another launcher so i can add some apps that i need (no not facebook or stuff like that) and perhaps root and rom it....
its running android 4.2.2... and i can get you the entirely too long software version
Its sad really because this could be cutting edge stuff, but someone higher up had to come up with ways to neuter this damn thing... and look i get that there are things i shouldnt have access to while driving, but it DOES have android web browser built in so its not like they dont want us using it...
i dont expect the world as this unit has only been shipping with trucks for a few months... and many of you may not have come across it... but perhaps it shares hardware with another system and panapacific just stole it (it HAS happened many times)
thanks guys and look forward to replies before i finish going insane

DEA600 - SmartDisplay for Automotive Infotainment
Hey,
I just came across your note while search for this product - I was the software architect/tech lead for the supplier company providing the Android port and the Freescale SOM component of the display screen on this product line - although moved on shirtly after the system went to mass production. - it is awesome to see someone here discuss it!
You are very correct on a lot of you assumptions and assessments. it was a very ambitious project that really tried to leverage as much of what Android was capable of at the time it was planned, but tuned to work as a smart display for commercial vehicles.
The display is only a part of a system of components. The display runs a port of Android 4.2.2 - but highly tailored to its environment - pairs with the Delphi radio unit (as a peer, not as an accessory) and is toghtly coupled to the unit in production. as a security measure.
unfortunately for what you are looking for, though much of the upgrade and app installation capabilities have been locked down to prevent side loading or execution of "unauthorized" apps that don't have special keys fro. the OEM or manufacturer. even if installed, the system manager will kill any apps that are launched without keys.
you may be able to get a developer key from the OEM but I don't know how they chose to mange that in the final system.
thanks for the posting, though - it was a small run comparatively for android systems but it was a pretty damn cool system with what we did get working....
I would be happy to discuss more if you want. - with what I can....

DEA600
hi there
i have same head unit in my 389 pride and class peterbilt, for the map part, that you can update by connecting it to your phones internet, either wifi hot spot if not then just connect it with bluetooth and use bluetooth tethering of phone and PAN of your DEA600, but main problem in the system is that you cant put a single thing without pulling breaks, and u cant download a single file by any means, it just displays error that unfortunately process.android. stopped or browser has stopped or settings has stopped. if any one figured out how to download anythimg in this little thing. please update
hello there. I have T-680 with DEA600. I had exactly the same problem and ended up taking my truck to a dealer. it turned out to be defected radio. After it was replaced, it would connect to a hotspot no problem ( im using htc 10).
I have the same unit in my W 900. It is a huge disappointment in many ways. First of all just like any factory radio I have ever seen in a commercial truck the sound quality is horrible. Second I don't like the fact that it locks so many functions when I am driving. I have a passenger that rides with me most of the time that is perfectly capable of safely operating those functions while I drive. This makes the GPS almost useless for the way I like to use a GPS. Good thing I still have my Garman. But really my biggest disappointment is the fact that I cannot get the gauges to work properly. It states that I can choose from over 30 gauges to be displayed however I have been unable to find any way to change from the six default gauges that are there. I have read the manual but it does not explain how to open the menu that lets you choose which gauges are there. I don't know if my unit is defective like one of a red one of yours was or if it just hasn't come out in an update yet. Also if I am reading this right it looks like my display and gauges function are tied to the stereo which means if I replace the head unit I'm going to lose that function. Am I reading that correctly?
Hey guys so a friend of mine has the DEA601 in his new truck and drives him nuts that the passenger cannot control things when its going faster than 5km hour (his old Peterbuilt worked fine).
I'm a software eng and would like to find out how to disable the Distracted Driver feature (like you can do in settings on many other Android Auto ROM's like Honda). What are my options here? a) Make a whole new ROM (but how to do that?) b) try to hexedit the existing ROM and find where the 5 km value is and modify it c) add an add-on app somehow to override this limit or d) other???
Any ideas would be greatly appreciated.

I found out in order for the guages to work I need an $800 module my truck didn't come with. Now my biggest problem is the technology seems to have stagnated. The software on my phone and tablet are no longer very comparable with Android 4.2. I try my iPhone and my Android tablet and neither will play Pandora consistently. I am forced to use Bluetooth which looses sound quality on an already low quality stereo. I really wish Kenworth had spent their R &D on making their trucks compatible with idatalink like most aftermarket stereos use.
At this point I am torn between installing a hideaway marine stereo with a remote display and leaving this POS Pans Pacrapic as a display with nono sound. Or installing a line converter and amp and dealing with this clunky software. I wish someone would make a rom to upgrade this thing.
Looks like the Mfg won this round

I'm driving one of these trucks also and I keep checking this post but I guess we havent incentivized anyone who cud help yet!
The electrical switch must be located behind the air brakes control knob. I'm sure if you pull the stereo out you will find the wires that control the disabling feature. The unit tries to "update" when connected to wifi. Maybe someone can use wireshark and grab the update packet and modify it with root installed. I'm ok with trying anything short of taking the unit apart and Jtag the firmware directly. Would love to see one taken apart.

This is a 2+ year old thread being g responded to.
What is your point? 2years later and still no solution to the problem. I ran across this thread of people discussing the same problems I'm having with the radio unit. If you got something usefull to add to this discussion then please feel free otherwise you don't need to acknowledge when what was posted that helps me null with my problem.
Anyone here figure anything out?
still nothing
Hello! So I have little tech experience but I am willing to work with someone here to sort this out. Got a 17 w900 that I put a aftermarket double din in and retained smart nav for the gauges. What I did find was the screen (not the radio) gets a input from the wire harness off the ecm to give data to the screen. So I’ll attach a picture of the plug and maybe we can use this plus find it’s female counterpart then get the other end to plug into a maestro box? My Sony doesn’t have maestro. I do have a pioneer that does but can’t justify the cost being the Guinea pig. I’ve already been one of the first to get the tilt column to drop LOW and managed to fit a true 7” double din where the stupid nav was.
I've looked all over for detailed information on smartphones NFC feature and it's ability to emulate an RFID card, but all I keep turning up is very generic information and can't find anything that really digs into the technical specifications and limitations.
This being the one stop shop of all things Android, it seemed logical to try here first to see if anyone might know more that the basic grab regurgitated over and over everywhere you look.
What I have managed to glean from my scouring is that NFC in smart devices operates at the 13.56Mhz range, which seems to be the standard for RFID chips available today. But apparently there's also another group of RFID chips using a much lower frequency of 125Khz and this is where I couldn't turn up any relevant information.
What I'm wanting to know is are the NFC devices backward compatible with the lower frequency? If not is there any sort of chip that acts as a bridge between the two bandwidths that would allow a newer device to communicate with an older one?
I guessing from the lack of info that the answer I'm looking for isn't what I'm going to get, but that's why I'm here, to find out for sure one way or another.
The long story made short to this inquiry is I have a aftermarket device that adds push to start feature to an otherwise ordinary keyed ignition automobile that uses RFID to enable the ignition system, but as I've uncovered it's using the 125khz frequency, that I very much would love to find a way to use my oneplus 8 pro's NFC functionality to be able to operate.
So is there any way I can make this work or am I just SOL and short 2+ hrs of my life for not just coming here first?
