PDA --> Car speakers?

Is that possible to send music to my car audio speakers through an HTC TYTN?
Thanks.

Yes, I use a 1 to 3 USB convertor and then plug a phono to cassette convertor.

yes it is, i done it myself
firstly you need to make one of these
youl need a 3.5mm stereo connector, cut the earphones supplied with your tytn and attach it to the connector

once you done that you need to get a radio transmitter (£15-£30 check ebay) and plug it into your 3.5mm stereo connector

as you can see there are different ways of doing it. You could also use a bluetooth enabled car radio (very cool)

i beleive my ways the cheapest, you can plug in better earphones into the tytn and get better sound aswell

i used to use one of those but stop'd when i got a car stereo which had SDcard input and usb input
was about 75$ so no biggi

my alpine stereo plays mp3 but playing tunes and even running tomtom thru the car speakers is great

can u explain how u did this.. once u cut the usb thing how do u connect it? just chop off a 3.5 thing from another set of ear phones?

have a look part way down this list of Artemis based goodies http://www.pocketgpsworld.com/modul...pic&t=48131&postdays=0&postorder=asc&start=51 there is an 11 pin mini USB to 3,5MM socket available as an accessory for the HTC devices, much easier than chopping up your headphones for a direct link try http://www.gpsforless.co.uk/product_details.php?id=6982
While looking for the above link I came accross this though http://www.gpsforless.co.uk/product_details.php?id=9736 Which looks even more suited to do what you need, having looked again at this last item I cannot believe what you get for less than a tenner, USB audio cable, USB charger cable and an FM transmitter, the whole lot can be used at once so you can charge the PDA and liten to music via FM - great - Mike

Xdaman85 - I've chopped the heads of a set of headphones for an orbit, can you tell me wire goes where in the stereo socket? I know I could buy an adapter but doing it myself is much more fun.
Thanks
Eoin

http://forum.xda-developers.com/showthread.php?t=284512 contains a wiring diagram of the 11 pin mini USB connector, that might be of some use when doing this - Mike

nope this has nothing to do with it.. because once u chop the wire from the headset the heatset only has 1 wire

Actually it does, because when I strip it back it contains all these wires. What I need to know is what is to be connected up in the stereo line socket and where!!

[Review] 3.5 mm Antenna for FM Radio, Pics+Video Included!

Tested On
Xperia X1a (poetryrocksalot)
What Is This Thing?
This is a "TMC Antenna with a 4-pole 3.5 mm jack".
TMC Antennas are used for reception of traffic data called TMC (Traffic Message Channel), but they can also be used as a more casual FM Radio Antenna.
Who Manufactured My Unit?
X-Plus (German Store on eBay)
How Much Did Mine Cost?
$26.81 (USD) with free shipping
When did it arrive?
I purchased it on July 10, 2009.
I received it today on July 18, 200

http://www.youtube.com/watch?v=cV_v3PQEX-o
Specifications
-5 inches long
-Best suited for frequencies between 80 MHz and 103 MHz
-3.5 mm headphone jack
-Designed for TMC reception
-4-pole headphone jack
Pros
-Adjustable Aerial
-Portable Antenna
-Practically Wireless
-Works with FM Radio
-Allows "Speaker Mode"
Cons
-Bad reception for frequencies higher than 103 MHz
-Hard to Straighten
-Prone to Breakage
Ways to improve FM Radio reception with this antenna
1) You can use your hand to hold the device or the antenna to increase the reception. (I suggest holding the device, instead of antenna)
2) Use the FM Radio outdoors or right next to a window.
3) Place it directly on a good conductor (metal and skin are good conductors).
Where to Buy
Italian/German HandyTech24 eBay Store (German Language)
German X-Plus eBay Store (German Language) [I Bought This One]
German "vhbw24" eBay Store (English Language)
Guys, I need your help. Please buy 1 from HandyTech24 and 1 from vhbw24. I would like to compare the quality and reception of these antennas. They ARE different antennas. Submit your reviews here in mythread.
Comparison to Headphones
My headphones have better reception, but I have to hold the headphone to improve the reception.
The antenna has good reception, but it must be placed somewhere that has good conduction or somewhere that has less interference (such as big metal walls). [the metal on the wall is a good conductor and therefore eats most of the radio by the time it reaches the antenna]
Empirical Data
Excellent Reception Frequency 102.7 MHz (KIIS-FM - L.A.'s #1 Hit Music Station!)
Decent Reception Frequency 105.9 MHz [Power 106 Where Hip Hop Lives!]
Awful Reception Frequency 106.7 [MHz KROQ FM-The World Famous KROQ]
Final Verdict
Sometimes the reception is crystal clear.
It takes away the annoyance of long wires.
It does not have the best reception all the time.
Headphones have bad reception anyways.
Overall, the reception is 65% as strong as a headphone's reception.
I give it a 70/100 satisfaction rate

Sometimes the audio quality crystal clear, but you need to place it on top of an aluminum trash can .
Don't worry though, I'm in the process in designing my own telescopic antenna that will be able to utilize the reception.

I get awesome FM radio quality on my X1i using just a normal pair of headphones - Sony MDR-V300s. They do have like a three metre long cable which helps though

I'd be interested, if the radio would output to bluetooth stereo headsets using this, but I'm guessing it doesn't.

Never will spend $26.81 (USD) with free shipping
for peace of wire...nothing special on it to expensive i manage to make one myself with less than a dolar, with just some broken earphones...and a copper solid wire to make it hard enought...More than easy....
Don't have to be a scentiest to make your own one...

i bought one like that on amazon! for 5.99€ just as a small tipp
and it works pretty well so far

clear in indoor?

Wish I could find this design
Made by a Taiwanese company called Comma.
Still would need a way to bypass the sound going from headphones if you wanted bluetooth or speaker sound.

Did you ever go on with your own antenna? I'm looking for a way of connecting to my house antenna (using my tablet), which would guarantee good reception.

Do you want to play music thru your EVO in your car?

Why drop $39 on a FM Transmitter when Amazon.com has them for sub-$15...

seams like there should be an app that leverages the internal FM radio to accomplish this feature.

The built in FM radio is a RECEIVER. It cant just be turned into a transmitter. Your better off using a bt receiver that can be plugged into the aux in of your radio,or just plugging it in. If your radio does not have one,about a hundred bucks will get you one that does,you can even get one with bt and avoid the cable or adapter all together.

Walmart has one for $11,(in the auto section, not electronic) and it's battery powered so you don't get feedback from the outlet.

I use a direct aux converter that replaces my radio harness so anything connected to my radio thinks its a cd and i can connect any audio device and even an ipod... but it was 80 bucks.

I think P.I.E. makes interfaces for almost every car. I haven't checked their page since I got my XM stuff in 05 but they've gotta have something that'll work for pretty much everyone.

FM transmitters are so 90s lol

Hey can you guys help me.. I just bought one(not this one) and it won't fit in my Toyota camry's cigarette socket or the 12v.. is there anything I can do? And do they make special smaller ones that fit?

You guys are saying I can buy this... Miccus BluBridge mini-jack Rx: and plug that into my audio jack in my truck and it'll stream the music via bt?

My car radio doesn't have a place to plug an adapter into so I use a Motorola T505. It's cheap, easy to connect to and I can take it from the car to the office if I want.

OK some good ideas here

I just use my AUX input in my truck

I bought the older version of this
GOgroove FlexSMART
Pretty handy piece of equipment, and it has gotten cheaper with the upgrade. It will charge your phone at the same time as transmitting your tunes. I use it to listen to the games while driving home from work.

If you have a way to attach a BT receiver, that is totally the way to go. A2DP sound quality rocks and you can use it for speaker phone too.

Its what I have been doing for months, and more. Not only that but the thing has a battery so it can run without a power source for a few hours. Although Im too lazy so I just leave it plugged into both the input and USB port (I use a lot of rentals, they have a cubbie hole with both). It goes to sleep mode but then once you restart the car it goes active and you just have to turn on bluetooth on the phone. No connecting anything.
Also, it works with all types of audio. Phone audio, navigation audio, etc.

Prepare yourself for "that's what she said" jokes, but it won't fit how? Too big around, or too long? As much as you may not want to, you might have to push harder or something, some of these things are kinda crappy and require more force than you really want to use while shoving them in. The 12v cigarette socket in cars is nearly 100% standard, and a common car like the Camry should have a standard socket. Be careful though, I'd hate for you to break the socket on account of my advice. I've had them work in every VW I've ever owned (81 rabbit, 91 GTI, 91 jetta, 88 golf, 92 gti, 93 corrado).
Pics and product info would also help solve the issue .

Glad I read this, some really good ideas.

I'm using the bt receiver from BlackBerry. I think it was about $50 from Amazon. I had some engine whine, but then I ordered a gnd loop isolator and all was fine. The whine was specific to my Mazda 3's aux jack, so you may not have that problem.

BUT... theres always a but right?
Thing is.. I do have sound on my rear speakers, including the OEM subwoofer, i saw many topics which people didnt had it..
So i do have sound, but sounds way to low compared to the front speakers, i tried setting the sound management a little bit centered more in the back a little bit like this image:
But still, the rear speakers wont sound as loud as they were on the previous radio which was 1 din aftermarket kenwood..
Any clue?
Another issue i have, on the previous radio i had information on my board display (the one between the Km/h signal and RPM), information about which radio station i was listening to, precisely the name of the station.
Now i dont have any information when i listen to radio, BUT if i use bluetooth and call someone, it shows on the board the name of the person im in call with.
Just an image to help out.
So any clue about those 2 issues? Thanks in advance

Apologize I can't help with your questions, but wondering if you can answer a few that I have......as I'm looking at putting a unit in my 03 A4.
-Can you post link to where you bought yours with all the specs?
-Have you tried streaming via Bluetooth (ie Pandora from your phone)?? Can you comment on the quality of the sound?
-You have a Bose or non-Bose system?
Thanks very much.

Ok, the first issue you can fix., the second - forget about it - they don't support it.
For the second issue I created a video on YouTube. If you read all the comments under the video you will find the solution of the first issue (someone named João Duarte asked me about it). Because this stupid forum doesn't let me post links yet, you will have to go to YouTube and search for "To the Erisin Support Team". Watch the video and read all the comments and you will have the solution to the rear speakers not loud enough problem.

Hey - did you get this sorted? Assume you have a half-amp setup in your car. I (and others) posted how to resolve this on an audi form (ASN). Let me know if you are still trying to figure this out and I can find the link for you.

use a "high lo adapter" for the rear speakers.
I did they same on my Audi A4 B7 (without bose system)
Sounds way better now

Hi can you explain where and how you wired the high low adapters. will the rear subwoofer also work then?

Hook RCA's to the rear speakers wires coming out of the stereo and plug those RCA's into the Rear RCA's hooked into the cars harness.
Stereo ->Rear Speaker Wires(convert to RCA, outside is ground inside wire is positive)<----RCA's on Car harness<---Car Plug.

MTCD/E PX5 Wonferfoo Unit, trying to find front cam CVBS

MCU Version: MTCE_HXD_v3.30a_2 , from Aug 8 2019 10:51:10
Aliexpress item ID: 32812618751
Hi Guys,
I've recently bought and installed the above mentioned head unit in my car, all singing all dancing with DSP, 4GB of RAM and 64GB of ROM Storage, and been fairly happy with it: It's snappy, fairly well built, the sound quality is OK...so far I've installed the external mic on the overhead console and the rear parking camera which is working great with FCAM.
Now, I'm looking into installing the front parking camera (not DVR, or AUX Video IN...the proper FCAM CVBS input mentioned on the fairly well known MTCD PDF Diagram). I've read on the forum that some MTCD units shipped with a missing connector, and that a quick soldering job to the connector pins within the main board would do the trick... Back in 2017, @hugovw1976 was forced to do a hack job of soldering pin 3 of the FMS6502 chip, plus adding the required condenser to tap into the said input.
We're in 2019 and my unit seems to be quite polished (not the installation or user manuals though) with no missing connectors and quite a lot of undocumented (and unused!) pins in the back panel. I've tried to get the complete pinout from the seller to no avail...conversations on Aliexpress have been frustrating at best, and infuriating at worst. I'm now resorting to the wealth of knowledge amassed on this forum, looking for a kind soul who might be familiar with this particular head unit backpanel pinout to help me out? Here are a few pics:
Back Panel:

Included Wiring Diagram (sucky), upon close inspection you'll notice that there is only reference to the back camera (top left, 4 pin sub-connector, with only the left-most 2 pins being used...tried using the remaining two which didnt work), also, the bottom right 8 pin connector is completely undocumented on this diagram, I tried every vertical pin pair with the camera but F-CAM didn't pick it up as the front camera...):
Main Board:

As a suggestion, try validating connections from MTCD schematic, forum thread found in my signature. It may not be perfect, in terms of component numbering, but good enough for someone with medium level electronic skills.

Thank you, I know about the diagram, and see that others have tapped into pin 3 (IN2, FCAM-CVBS), but I was avoiding having to solder on those tiny legs....the MCU in particular seems quite hard as to not short anything...I'm hoping that my unit has the FCAM-CVBS input circuit already in place towards the back panel pins

The idea is to trace back, to validate the pins or identify what is needed to implement front video function, incase the pins might be correct for front video, but manufacturer has omitted components.

Retrocamera
I tried to connect on a px5 Mtce has (Dasaita) mcu 3.4 universal rear view camera on Renegade, without connecting PIN reverse canbus, powering up reversing light. For a while with fcam it went (not automatically) but with time I think I burned the camera. Now the led light works but on the screen I only see rustles and the navigator monitor turns off after 10 minutes. Which are the right connections
