hi,
this is my first thread here, sorry for my bad english - but i'll try my best.
i want to connect my xda2 with the 22 pin-connector for mp3 in my car.
in your conectors-page is a note:
Audio needs to be capacitively coupled in, any DC bias seems to inhibit audio
i want to ask, what c is needed here? (how many farrad, what kind of C)?
please can you give me some tipps?
is there anyone who has built such a connection? is this a good way to connect the xda2 through the car-radio, or is it better to connect via audio-jack?
my opinion: i found it very uncomfortable to connect first the audio-connector (specially in the dark), and i would be very happy if it works through the 22-pin connector.
please please...gimme a tipp.
or did anyone connect the xda2 and car-stereo without couple-c?
c'mon please, a little answer and i'll be happy.
anyone must have finished a 22pol-connector by himself, or am i wrong?
ty
frustrated...(bad first experience)...
you may be asking too much of a technical question for the cuurent people who watch this board.. i get the impression that the xda-developers site started out with a lot of smart people reverse engineering and dismantling the devices, but its now become more of a software tech support site than a hardcore HTC guru site..
Hi there sorry to hear you have had a bad experience.
as stated xda-dev no longer is as good as it used to be.
i had a quick look at the diagram and from what i can see you should not need capacitors at all.
from what i can see if you connect up pins 3 and 4 to the necessary inputs on your stereo the sound is fine.
a problem i can see however is that to get output on these pins you need to attach pin 19 to ground with a 10k resistor...but this will also redirect the microphone so you wont be able to use it as a phone whilst you have it plugged in unless you also build in a microphone (mind you this should be pretty easy if you wish to do it).
hope that helps

Hi all,
I'm a massive fan of this site and tell anyone who has a HTC device to check it out. This is my first post though so here goes.
I have an XP laptop on which I watch movies mostly as avi's. I have the Sony Ericsson HBH-DS970 which won't work on my laptop as it doesn't have A2DP. What I would therefore like to do is to watch the movie on my laptop and stream the audio portion over my wifi network to my Jasjar so I can listen to it through my headset.
Is this possible? If so how?
I will point out at this point that, while I'm not a complete muppet, I have never had anything to do with streaming of anysort so a tutorial might be useful. I have tried to figure it out using bits taken from several threads on this, and other, forums but so far with no luck. Ok so maybe I'm more muppety than I thought I was.
Yes I do know I could get some wireless headphones with a base that plugs into my laptop and do it that way, but where's the fun in that?
Any help gratefully recieved.

So what do you have to do to get a reply around here. Always seems easy for others. They ask a question and somebody answers. Guess nobody has an answer. Now thats really diassapointing.
i think response problem is a combination of 2 things: you have a really rare question (i didn't search, but from the looks of it it is), and you didn't wait long enough for that kind of question.
I don't know what type of bluetooth services the uni supports to other devices other than serial.
Apologies
Thanks for te reply skywriter and sorry for rushing people. I didn't realise what I was asking was so hard. I just thought it was me being stupid. Well if anyone does have an answer I would be happy to ear it.
Hello all,
My Qtek 2020 (Himalaya PH10B) fell on the floor with the headphones on, and the mini-jack for connector for the headphones broke inside it.
I successfully opened it, and I was able to see the damages. I can see only 6 pins that connected the mini-jack plug to the main board, and it seems that there could be a seventh that got broken...
Would anyone of you know of a closeup picture of this headset plug/connector ? Do you know if it is possible to find a new one ? If not, mine looks reparable still, but I would feel reassured if I knew the exact connection here
Thank you in advance for your help.
Cheers
Thomas

Thank you for your answer Rudegar,
I re-soldered the connector, and I realized that a pin was indeed missing. I actually found it freely moving inside the PDA, but I could not solder it back to the connector. The results ? Well, it still does not work, unfortunately... With the headset on, it is mainly okay (there is still a little contact problem) but *withou* the headset, it still has no sound...
So :
1) Can I find this connector somewhere ?
2) Is there a way to tell the PDA not to check for the headset, and use the main speaker all the time ?
3) Would it change anything if I bought a blutooth headset ?
Thank you in advance !
Cheers

1.) i doubt it would be a cheap option if htc had a special connector made just for their phones so i'd asume they use some sort of std component
and maybe there even is a partNr og serial on the connector
which could be used to find a replacement in R&S catalog
http://www.rs-components.com/index.html
2.) no pretty sure the switch between headset and internal speaker is don in hardware and software cant control it
3.) no with bluetooth headset you just dont use the audio connector which mean it would be empty and you'd have no sound on the pda
but it would prob solve poor contact issue of your current headset
Thank you Rudegar !
I am going to re-open it and check if I can find any serial # on the component. It looks like it is my best option. Obviously, if I find something, I will post it on that forum, so that other people can know...
Thanks again !
Cheers

Hi guys, is it possible to have bluetooth stereo on my wizard. Is there maybe a particular rom i must load.
Can any1 help me with this.
Doesnt anybody have any information on this topic.
Dude. Patience.
This site is analogous to a bulletin board, not to a chat room. Sometimes, it takes days before someone with the right answer to your question reads your post. Sometimes, it never happens....and you will almost always find answers if you run a search. You certainly aren't the first person to try upgrading the bluetooth on a Wizard.
To answer you, Yes. There are several options available, ranging from difficult (manual editing of your registry) to easy (load a .cab file or two) to way overdoing it (loading an entire ROM just to get BT stereo) with varying degrees of popularity and success throughout the user population.
I have heard this works on some Wizards:

When I was using WM5 only, I used this successfully:

If you're in love with the idea of flashing an entire ROM for more reasons than just stereo bluetooth, do some reading first, and make sure the ROM you want has "A2DP" capabilities, or you'll be right back here looking at my suggestions again.
Welcome to XDA, and please don't forget to search before asking questions. You'll often save yourself a lot of time and frustration.

BLuetooth stereo is built into the Wizard, with the standard ROM, at least on my T-Mobile (USA) MDA
You just need a BT stereo headset.
Thanks Myrddin Wyllt for the welcome.
Sorry about my impatience i would just like to say what a gr8 forum and you guys are doing amazing work. Been spending hours reading all the post and I hate reading so this is definitely good stuff.
Thanks
Hi all
Does anyone know of a tweak to allow radio to be played without inserting a wired headset, I often listen to music via bluetooth and would like the option of radio as well, thanks in advance.
By the way, I did search the forum before posting this as I know you guys have certain protocols in place.
Cheers.
try this and see if it works
Change the following registry : HKLM\System\State\Hardware\Headset from 0 to 1
hi, thanks for the reply.
I don't have my headset with me today but after I changed the reg the radio still would not play directly through the phone, what exactly should this reg edit do?
it should make the phone think that a headset is plugged in..havent tested it myself to be honest but it should work..however whether or not you will have a signal from the radio is another story
Dude, ther is no use for this... Even if you would get the device to start the radio without the headset pluged in, there would be no sound since the headset is the antenna...
So it would be like you are watching tv without cable... no reception!
There must be at least something in the mini usb plug. I found that it works at least a little bit when plugging in this thing only and playing the sound over the internal speaker though reception is poor at best.

Good luck!
There is some use to it... although the wire is the antenna the phone will act as an antenna also so you will recieve some signal it just won't be as strong.
Without fully testing there is no way of telling how good the signal would be, surely a phone that can pick up a GPS signal and a mobile signal should be capable of also picking up a radio frequency?
no, its not possible:

ok, I get the message. Thanks for all your help.
OT - I searched "Radio without Headset" accross this forum and had no hits.
I noticed that innocent people get shot down when they don't search before posting a question, how are they supposed to get decent results with a search engine that doesn't work properly. - Great site guys, the people here really know there stuff but perhaps go a little easier on people who search to no avail before posting. You don't have to reply to the post and if you do wouldn't it be best to simply give the answer or direct them to another post, up to you but it doesn't help anyone to just put - SEARCH THE FORUM or RTFM (a new one on me!)
Hope you see the point of this post, I am simply giving my opinion as an outsider who has just purchased a Diamond and I'm just getting into mods and tweaks!
p.s. Loving the GPS cycle computer. Best app by far!
GSM is in a very much higher frequency band, so it uses a very much smaller antenna than you would need for your radio. This is two very different systems. It will not work without an antenna
Hi Forum,
yesterday i started playing around with my new head unit. I got a great help from typos1, i want to thank him again for all he has done! First, i updated my MCU to 2.91. This worked withaout any problems. After that i flashed the custom rom from Malaysk. In my opinion he did a great work BUT for me, everything was a bit slower, everything looked not that harmonic. I decided to install Booroondook's custom rom. What should i say: works like a charm! Absolutely brilliant! Looks amazing and works quite fast!
The Details about my Unit:
Naviskauto C0255 - MTCC KLD6 v2.91/ - RK8133
There are a few questions now and i hope you can help me...
1. 3G Stick
At the moment, the HU gets internet from my smartphone peria z5 compact. I tried to connect a Huawei surfstick in one of the two cables "3G/USB", nothing happens. I tried to connect a 1and1 MT10 surfstick, same same... I've read from other users that they successful connect 1nad1 surfsticks out of the box. Do i have to start the stick somewhere?
I ordered this one now, specially designed for my unit:
https://www.amazon.de/gp/product/B0192YOBLI/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
I hope this one will work. If not, my idea is to set up a Accesspoint in my car and let the unit connect to this AP. I also ordered this one:
https://www.amazon.de/gp/product/B00634PLTW/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
I don't want to use my smartphone as access point for different reasons. Do you have any idea?
2. Microphone
The unit has a build in microphone ANS a 2,5 jack for external Mic. The build in microphone is absolutely bull****, i am not able to have phone calls, no one understands me. If i connect the external mic, nothing happens. I've read a lot of stuff about the mic problems and if i got it correctly, there is no chance to stop the internal mic... and as long as it isn't stopped, the external will not work. Some wrote that they work BOTH TOGETHER but this is wrong! One solution is, as far as i understood what i read, to open the unit and cut off the red wire from the internal mic. When cutted of, the external should work. Can someone confirm this? If yes, is there no chance to say android to stop the internal mic?
I ordered this one:
https://www.amazon.de/gp/product/B00XL1VLJY/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
Its a stereo mic, i hope this will work one day at the jack port of the unit because originally there was a mono mic included in the package.
3. Buttons and illumination
My buttons do not glow in the dark! I can go to settings and choose a button color but when i push on a color, the buttons on the left only work for 2 seconds. Even if i press on "save" after choosing, the buttons do not glow. Does anyone has an idea? The buttons should always glow! Did i miss to connect a cable?
I hope anyone can help me with those 3 questions... Would be great. Sorry, i am an absolutely beginner and im so glad to have this forum. Even sorry if anything is already answered and i did not found it...
Thanks a lot!
Greetings, Mirko
PS: I want to say a special thanks to Booroondook. It's amazing how people sacrifice time for others!
Theres a solution for the poor mic in the MTCB hardware mod section.
In the wiki (in my signature) theres a guide for 3G dongles.
Go into settings/factory settings (password 126) and tick the box to turn on the LEDs.
OK, i don't have the USB Stick with me but i will try tomorrow.
I cant' find a thread concerning the microphone hardware mod, the search function does not work here. Do you have a link?
The LED's work now
Thanks
