quick question about the TP2 and car stereos.

most car stereos today have a USB in for connecting an IPod, Zune, whatever.
do these work with the TP2?

Probably yes (haven't tried it myself), but when you connect your TP2 to an USB-host (which the car stereo is), the TP2 asks you which mode you want (Active Sync, Disk Drive or Internet Sharing). If you select Disk Drive, the microSD card shows up as a diskdrive in windows (or your car stereo...)

Yup, what andrehj says.
All devices that show up as Mass Storage will definately work on car stereo's. Worked on mine. But I never use it. Because mine has Bluetooth 2.0 A2DP support (stereo streaming). It works flawlessly.
No wires for me. Except the charger itself. xD

Simultaneous program access?
I can confirm that the TP2 works in drive mode as an input for a car stereo. However it appears the phone restricts access to the storage card in this mode and programs cannot access it, which means things like TomTom cannot access maps.
Does anyone know a way around this? Is it a WinMo restriction or something else?

Please specify "drive mode"?
I've used mine playing music through A2DP in combination with Tomtom Navigator 7 + Benelux maps.
The only downside I experienced was that the Tomtom voice was much louder than the music I played. Thus when adjusting the music volume to a much louder level, that Tomtom woman scares the heck outta me. Like when needed to take a turn, it's more like "GO LEFT!!!!!! W$E%T#@$%[email protected](#%|(!# ". In between the music.
No problem with tomtom reading the maps though.

'Drive mode' via USB
Thanks Crix84. By 'drive mode' I meant the Disk Drive mode that you can select when connecting via USB. I expect accessing via the BT profile is quite different which is why things work for your setup.
That TT girl would be scary at high volume!

Ohhh okay now I understand. You mean't the mass storage function I was talking about in a previous post of mine.
Well for what I've found and experienced. That mode makes the phone really function like a USB stick aka Mass Storage Device. At that moment only the MicroSD card is blocked from access within the phone. For what I know, the driver used for Mass Storage (any windows system or other) is a standardized universal driver. Wich means it must be as illogic to access the card both from within the phone and the computer/car-radio through USB at the same time. Like using 1 usb stick on 2 pc's by using a usb splitter. Device in use means in use.
Active Sync in the other hand uses a different kind of USB connection. It accesses the phone itself, through that, the card. Mass Storage is a direct function to the microsd card. Kind of a bypass. For compatibility issues. When you just want to put something on your card without the hassle of installing drivers (on old pc's) etc. Wich would really mean that the maps on the card for Tomtom are inaccessible. That would really be indeed a problem. The only solution for that is either use the phone as I do. Bluetooth A2DP not available? Then the car-audio system should change the access mode to the phone. Maybe an active sync like solution/connection. Problem is most manufacturers do that. Thinking of only using a USB stick on the radio. Mine does that too. Only mass storage devices are accepted through my radio's usb.

3.5 to usb - will it work?

I have a usb connection on my car music system, the idea is to play toons via a memory stick as opposed to cd. it recognises wmv and mp3. so, my question is, if i can get hold of a lead with a 3.5 jack on one end and a usb plug on the other, will i be able to play the music on my HD2 on my car system via the usb socket on the car player?
Mike

is not possible.
USB cable handles digital files (bit), your car recognizes the pendrive as hd2.
the jacks 3.5 is a analogic audio, you should connect it to aux to play the car radio and HD2.
therefore there is no possibility of having a USB / jack 3.5
excuse my English, is a google translation

thanks for your quick reply
its a shame it wont work as it seemed a quick fix.
am i right then in guessing that a lead from 3.5 on the phone to the aux socket would work?
Mike

Well, what I dont understand is:
Why go so far ?
I would guess that the music on the HD2 is stored on your memory card, and not on the device itself.
So - Just connect the HD2 with it's usb cable to the car USB port (where you connect the disk-on key thingie), and select "DiskDrive" mode on the HD2.
It should work just the same.
Enjoy
(And - report back)
Another thing - if your car has a USB port, I would guess it has a 3.5 port (AUX) input.
Try connecting the HD2 3.5 port to the car's 3.5 port (the 3.5 to 3.5 male-male cable is not expensive)

ok, usb does not work. you do get the option of active synch or data when connection but neither allow you to access music.
have ordered a male to male 3.5 jack lead to try that connection cos the car sound system has a 3.5 out and says that it is iphone ready.
fingers crossed and will report back either way.
Mike

well, I tried it with my car.
I copied an mp3 to the storage card (to the root folder of the card) and connected the hd2 to the car's usb port.
When the hd2 asked I selected "Disk Drive" and the car read and played the file.

thats interesting, i didnt think of putting a toon into the root folder. all my music is in albums in the music folder on the card. guess this is why it couldnt see it.
having the music as separate tunes in the root not as albums wont work for me but may for some, which is great.
still waiting for my 3.5 to 3.5 male cable and will report back when it arrives. as the music ctr in the car is ipod enabled my hope is that i will be able to select album and tune via the phone and it will play through the cars system.
either way its another great use of the HD2

I have all my audio in folders, many 2 or 3 folders deep, and the HD2 plays them on my car stereo with no problem.

Technically, when you choose Storage mode for USB, it emulates a USB-ATAPI device. Generally, these USB MP3 players require you to insert a standard USB-ATAPI device that is formated in FAT16 or FAT32. Some USB MP3 players support other file systems as well.
Honestly, I don't see why it wouldn't work.

what connection are you using?
Mike

happy to say the normal usb lead from phone to music system works fine. as has been previously said, simply choose the storage/data option.
stating with a bit of a blush here, i was not patient enough for the system to find the music on the storage card so assumed it was not working.
yay, can listen to me toons now. what a great phone this is.
Mike

For future reference for anyone. Use the FM TRANSMITTER.

Weird, i just connect my phone with the USB cable and chose disc drive and the car stereo finds all my music thats on the phone.
EDIT: Aha, you've got it to work now

[Q] Audio Through USB

I'm currently aching to be able to play my own music through my car speakers, weird place for this yes.. if it's the wrong section to post this please let me know.
But, I was wondering if it's at all possible to feed the phone's audio through the USB.
For example, I have a USB port on my stero in my car, and when I plug it in..i'm able to feed off my SD card to play the music thats on it. But.. I'd like to be able to play pandora as well..which I'm currently unable to do.
Was wondering if this is possible. If i've confused you feel free to ask more questions
XtaC318 said:
Since it isn't possible.. what about an app that allows me to control the music played? I can stream music from the sd, but its got to mount to read therefore I don't have access to the stock music app. Only way to control what's played is the buttons on the stero and its pain staking..

I don't believe this is possible. As far as I know, when you use the usb the deck itself is decoding the mp3's (or whatever music files you're using) directly. It doesn't support playing music through the usb, it just uses the usb to get the files. I hope that makes sense...

So is that why I ca never plat music on my xbox whenever I have a phone hookedup to charge? I thought my xbox just didn't play nice with phones

So your car stereo has a USB input but no auxiliary? If so, your best bet would probably be to get an FM transmitter. Like the poster above said, your car's stereo is merely mounting your phone as a mass storage device and reading the mp3 files off the SD card and decoding and playing them locally.

It sees it as you do on the computer, just a drive. The only way to get what you want is to use a source from the phone that plays audio. Head phone jack or Blue Tooth. Your stereo... if it has USB should also have an AUX input or BT. Havn't come across to many that have USB and not an AUX or BT. Its nice though... having Pandora in the car.
If you tell me the Model of the Stereo I can help you out. I have seen a BT to FM Mod. Those are kinda cool. If your in a pinch with a stock stereo.

Makes sense. My stero does have an auxiliary port on it, but due to recent events I'm really short on cash lol, was wondering if there was a work around so I'm not limited to my sd for music.

Nope... The phone isn't even connecting to your stereo. When you put it into USB mode so it can read the SD, it unmounted from the phone. Its as if you pulled the SD out and slid it into a card reader. When you pull the plug... It will remount to the phone. You'll notice it scanning for media at the top.
Now when you go BT... You can control it via the stereo or phone, using the Aux you can control it by the phone. "They" could make the phone controllable via USB like an Iphone but they would have to built that into the stereo like they do the Iphones/Ipods. Not likely to happen unless the Galaxy S takes off like IPOD did.

In theory, a rooted Epic with proper kernel support and hacked cable (since they don't exist commercially) can repurpose the data pins on its USB port for left and right analog audio thanks to the Fairchild FSA9480 USB switching chip inside the phone (the same chip enables the USB pins to be repurposed as a serial port with nonstandard voltage levels, enables the normally-unused fifth pin to be used as mic input, enables it to be used with a special "JIG" interface for JTAG reflashing without having to hand-solder anything to the microscopic internal pads, and apparently can also work its magic in conjunction with a chip by Silicon Imaging to use 5 pins to output a signal that can be transformed by a companion chip (embedded in the cable's connector shell) into valid HDCP-compliant HDMI. I'm pretty sure the 9480 can also repurpose the two data pins for external I2C, but don't quote me on it.
Check out the I9000 boards... they're about 2 months ahead of us. If you google for FSA9480, you can find a brief (but revealing) dialogue between a Samsung engineer and the Kernel.org folks regarding a kernel addition to support the chip. He had a few issues, because on one hand he's apparently not allowed to say much about how the chip works or what it does, but the kernel folks managed to wring much of it out of him one juicy detail at a time. If you check Fairchild's site, they don't even acknowledge that the chip EXISTS, but it's been photographed inside all the Galaxy S phones in various teardowns.
In English -- yes, the hardware exists today to connect your phone to a stereo's analog inputs via a cable that repurposes the USB port... but the official software to make it work from Samsung and Sprint doesn't exist, and the information needed to make it work ourselves on a rooted Epic with AOSP isn't quite available yet.
I'm personally quite happy about the uart, because that means we DO have an easy, low-ceremony way to do i/o between something like a gamepad built into a hardcase a-la-iphone-GameBone that doesn't require Bluetooth (note that if something IS using the USB port for UART purposes, the USB port is still active, but the phone sees it as having nothing connected because the signals from the D+ and D- pins are physically re-routed by the 9480 to the CPU's UART pins. Think of the 9480 as being like an old-fashioned telephone panel with cables that can be moved around to connect the USB port's 5 physical pins to different pins inside the phone.
I'm now pretty sure that this is why there are exactly 7 contacts on the microUSB connector inside the phone -- 5 are used to get the pre-HDMI signals out of the phone, and the other 2 (3, if you count the ground/anchor tabs and assume they carry a signal as well in addition to mechanically anchoring it in place) are used to supply +5v and ground, and possibly one wire for half-duplex signaling purposes.

Wow that was a lot of info... lol. I didn't know that about the usb tho. That's good to know. I was thinking of taking it apart to see.
But... I think he's wanting a UI via the USB like the way some players will do for the IPODs, not analog. To go throught all that when the Head Phone jack will do the same... I could only see that if it was broken or if you really really want only one cord to the phone.

I've got an Alpine unit, I hook my USB up - turn on the TUNER. Mount the Drive and once the phone is done - swap back over to USB and i can get all my MP3S. sadly I get all of my ringtones too - odd when the radio is full blast and a track changes - none the less works well for me. Try it.

I purchased this Kensington LiquidAUX Bluetooth Car Kit for my phone a few days ago. It works perfectly on my sister's iPod touch (no AVRCP [silly apple]) and an old WinMo 6.1 phone.
I just got my Epic in the mail today so I'll be testing it out soon.

WTF. AVRCP (bluetooth remote control) is really buggy with this phone. I used the LiquidAUX with an old Omnia for a week with no problems. The Epic connects and plays audio just fine. I can also pause and play music but the forward and back buttons don't work. When I first pair the phone with the device everything is fine, but after disconnecting and reconnecting the remote control stops working. I got it to work after un-paring and re-pairing but it only worked once.
The Moment I had before this had really choppy audio.
EDIT: I had the phone opened up in DDMS and the phone is receiving signals from the remote. But it only reacts to them when the media player is on the screen. Weird.

Sat Nav In Car

Just moving away from an iPhone and getting used to the way the DHD works. Much better!
There are a few issues I am having though.
I have a JVC head unit in my car, which I plug the phone into (USB). What I want to be able to do is have it charge, use the sat nav and also play my music.
When I plug it in and choose 'charge only' it cant find the music. So, I choose 'disk drive". The music then works, but the sat nav doesnt. It says that the SD card is not installed.
Any ideas?

When you connect the DHD as a USB "Disk Drive", the phone actually unmounts (ejects) the SD from your device, so that the external device can read it as a flash drive. Technically, when you are on DiskDrive mode, your phone has no SD.
EDIT: Forgot to say that most (if not all) SatNav programs keep their files on the external SD
If you try installing the SatNav software on the DHD internal memory (have never tried it, it really depends if the software allows you to do that), and not the SD, it might work.
The last choice you got is the USB "HTC Sync" mode, in which case, although the DHD does not eject the SD, your JVC stands absolutely no chance in reading the specific format output from the USB (requires PC with proper HTC software).

Thanks.
Surely thats a severe limitation? I want to be able to plug my DHD into the car stereo so I can listen to music, get sat nav and charge. Surely thats not too much of an ask, and something all my previous phones have been able to do.

I have USB input on my car stereo too. I've never been able to mount the microSD card within the phone OS (WinMob or Android) and also play music through the stereo; Your phone either treats the card as USB mass storage for your stereo, or for your phone, not both.
I only ever use Google Navigation on my Desire HD, and I have a 16GB USB stick for music. It only leaves my car if I want to change the tracks on it. Maybe one of those solutions will be best for you.

Navitel working great?

The only option of listening to music from the SD card and using navigation software that holds the maps, voices, etc. on the SD card (I think most if not all of them are made that way) is to use the AUX input of your car stereo and play the music with the phone's music player (the quality of the AUX input is not so good on my Sony). That way you'll have your navigation voices also through the stereo, but there was a thread somewhere that in order to play the voices the software pauses the music. Haven't tried it though, so I can't comment if it's true for all the navi softwares.

You can try Dual Mount SD from the Market, but it requires root in order to work. When you install it you can use your sd card in the phone and through usb at the same time. There is no solution without root.

Thanks for that. Tried it and it kind of works.
Its a bit odd though as the DHD doesnt know what songs are being played - if that makes sense. Its just passing through via USB. If you set up its own music player to do something, it plays that via bluetooth. Kind of cool in a way, but just means you can only control whats being played via the car stereo.
Thanks again, much better than it was.

Alpine Deck support on Samsung Galaxy S2

Hi Guys,
I got a Alpine Deck (ida-x100) in my car and everytime I plug in the SGS2 it makes the USB Connect noise continutiously and doesn't detect, I had a HTC desire and the phone worked with no issues (just no library support) Does anyone know if there is a way to resolve this issue?
It would be awesome if you could emulate the iphone library environment and make it compatible with Android!

Hi man, you can buy the alpine 400 kce bt receiver for ida x100 (I've got it too) and connect ur phone with this; the results are very very nice...handfree call, music, vocal command ecc ecc

Thanks man, might consider it
How do you control music/audio? is it via the alpine deck or the phone UI?
Also - what do you use for voice control? vlingo?

I had this same problem (constant connection bleep and storage not found). Alpine Support said the phone is not compatible but this is incorrect. You need to connect the phone as a Mass Storage device, not as a phone.
To do this select Settings > Wireless and Network > USB Utilities > Connect Storage to PC. Then connect to the Apline headunit via USB and I think you have to select Connect again on your handset. You have to scroll down through the first menu on the headunit to Music and hey presto.
Whilst in mass storage mode I do not think the handset has any other functionality. Personally, I am just going to keep a large USB stick in the car so that I can use the phone for GPS and calls (safely, obviously!)
Worth bearing in mind the Alpine only works with MP3 AAC and WMA.
