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.

A couple of annoyances - screen lock and charging

Hi all,apologies if this issues have been asked about before - I have locked but couldn't specifically find what I was looking for.
I use my HD2 in the car to play music, whilst doing this I want to use the USB port on my stereo to charge the HD2... however the USB mode on the HD2 kicks in and then disables my memory card from being used directly by the phone. Setting the USB mode to activesync makes no difference.
Having plugged the USB cable in it would be nice if the stereo recognised the USB card when I wanted it too so that tracks could be read directly by the stereo. Other USB storage devices I have work fine but setting the HD2 to USB - Disk mode makes no difference, the stereo does not read any tracks. Anyone had this issue too?
Whilst using the HD2 in the car, playing music (charging or not) I'd like to prevent the screen lock for activating, I'd be happy if the screen darkened but with one tap of the screen I would like it to be back to working brightness and active. Is there a tweak to allow this to happen and for the lock to be set manually, for example by pressing the poweroff button?
Thanks all
Dan

It just sounds like your music collection is not compatible with your stereo. When you plug in the USB cable and select "USB drive", yes, it will stop the phone from accessing the SD card, but if you want to play music via the stereo then who cares!
You can also set the backlight to stay on when connected to an external power source (settings, menu, all settings, system, power, backlight).
That should solve all your issues.
Don't forget, it's not just the file type that your stereo might be finniky about. It might not like the bitrate of the tracks either.
Hope this helps

Thanks John...
I'd rather use the HD2 to play the tracks to be honest, with coverflow it is much easier than the clunky button method on the stereo.
Will the back light option also disable the screen lock? Assuming I can't power the HD2 from Stereo (because I need to have the HD2 access the memory card). Then I will have to set the backlight to be on permanently and that will kill the battery Ideally I need to be able to create a profile based on certain circumstances.
The stereo also has a SD card reader so I will try the card from the HD2 in the stereo direct and see if it has any problems accessing the files.

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

USB DRIVE?

Ok so i bought a data cable when i first bought mew HD2, so i could plug it into my car and listen to my music on the radio and it worked for a month or so... Today it has stopped working, the radio says READING USB DRIVE, but nothing ever plays. It flashes to my radio and then says READING USB DRIVE again can anyone help me?

Did you tryed restart phone? You'r sure you select data transfer mode?

maybe u didnt activate USB drive mode, go to settings in manilla and configure that at the "other" settings (dont know exactly where, not using manilla anymore >.<)
sure it doesnt work if its in active sync mode..
it should work whenu switched to USB disk drive mode Oo

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.
Sent from my Desire HD using XDA App

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.
