BA as car(pocket)pc

I've bought a used xv6600 off ebay which I'm going to convert to a carpc.
As a first time BA user, i have a few questions.
I have read the wiki/searched the forum, but I'm a bit mixed up and hence posting this thread.
installed versions on the phone:
model: PH20A2
ROM version: 1.36.00 WWE
ROM date 01/13/05
radio HA01_151
protocol AA.3.3.3.01
PRL 50619
extrom 1.36.116 WWE
hardware version 0041
a few notes:
- Its not going to be used as a phone as I can't register it with my local cellular provider (although they do support CMDA EVDO) - so I couldnt care less about if its radio works..
- Its going to be paired to a BT GPS from socket.
- the BA/xv6600 is going to be permanently mounted into the car (I'm still designing how, it would be in horizontal mode though).
- since It'll be permanently mounted, I won't (and couldnt) use the keyboard..
- audio out is going to be used to connect to an external speaker
- the BA will be charged from the car's 12v (always connected).
my questions are:
1) where could I find schematics for getting audio output (if exists), as well as where to connect the charge directly to the BA's connector.
I have only a cradle, no sync cable, which means I'd probably have to open up the BA and soldier directly, or get a connector...
2) should I connect audio out to the connector (if possible?) or the 2.5mm output on top of the device.. ?
3) I'd be interested in upgrading to WM5, I've read on the forums that it isn't possible on the CDMA versions because the radio doesnt work (or does it?). Since I don't care about the radio, could I install WM5 ? which ROM would be suitable for my BA model ?
awaiting your answers,
thanks!

Sounds like a neat project

Might be a bad idea...car batteries are designed to give out high power for short periods, not low constant drains. Personally I'd connect it to the ignition circuit so it's only powered when the ACC line is live. This will also turn it off for you after X minutes if you use the "auto-power off on batteries" function. It may even turn it on for you!

The connector does have audio available. Buy a cable and hack it because if you mess it up you just buy another. Messing up the connector itself on the phone is more fatal. I think the schematic is on the wiki for the actual pin outs.
You might also find these useful:

yes after constant searching , i also found those threads.
Yet I'm wondering, some connectors don't include all 22 pins, but only the ones actually used for charging (for example) - and then it'll be really hard to hack them.
I guess i'll just have to hope I buy one that does have all 22 pins installed... unless you have other idea's for me.
Also, for the charger, you're right, I didn't mention that, but thats somewhat my intention.
Since the unit will be permanently mounted, I won't be able to sync it (unless I bring a laptop to my car) - could I somehow get a two SD cards installed at once to the unit ?

Yes, that's correct. If you get a charge & sync cable you'll have most. Might need to take audio from the 2.5mm jack in that case. That's probably the simplest solution if you cannot get a fully wired one. I'm interested in this sort of thing, so if you could post an update on what you go with I'd be grateful.

I doubt you could get two SD cards. What may be possible is some sort of SD card extension device. Never seen one (never looked), but if it existed you could have a dash-mounted SD card.
Bluetooth or WiFi might help you e.g. with WiFi you could browse a network share to copy music over from your house. Also, there is a tool for WM5 that turns the phone into a keydrive, i.e. a USB mass storage device. Unless you need contacts etc sync'ed, that might be a bit simpler & give you more options to what you can hook up for.
PS bluetooth on WM5 isn't all that great. There is a "fix" that wakes the device now and then. This would light up your car overnight and might possibly be a thief magnet. On the other hand, if the battery dies on WM2003, you lose the data on it.

- At first I thought of making the device extractable, so I thought it'll be better to use the connector on the bottom for audio, but I've decided not to go this route (more complications and harder to make - also makes it easier for thieves.
So I'm probably going to go for the 2.5mm jack for audio.
- as for SD, since the SD slot won't be accessible, I thought of making an SD slot on the dashboard - and I'd like to switch between both.
an SD is connected via 9 pins, meaning making an SD switch is possible, but you wouldn't be able to use both.. thus I was wondering if software/hardware wise there is a builtin capabilty of such a thing as using two SD's at once. that'll be really cool.
- unfortunatly my XV6600 does not have WIFI, and BT is NOT an option for syncing (too slow !! - just imagine syncing 2gb of audio/vid via bluetooth..)
the two idea's I've had is making a USB connector on the dash (just incase I can get a laptop in the car..)
and the other, was the dash SD slot..
- for bluetooth, can't I just disable auto wakeup ?
- how will upgrading to WM5 save my data even if the battery drains ? its the same RAM chip's, not flash ROM, isn't that right ?
- as for HR's, the question is if I can somehow get the unit to 'working order' by installing software from the SD card, without actually syncing it to a computer..

fraser: Since I'm going to be connecting the ppc to the ignition circuit, and I'd also like to have a USB connector on the dashboard, I'd need to switch between the two.
i already have a car 12v connector -> usb charger device.
Should I buy a SYNC cable and convert it to charger, or car charger and convert it to USB cable ?
(although car charger might not have all the right pins..)

Never heard of that I'm afraid. A switcher may work, but make sure there aren't any other physical switches that get tripped when you put a card in.

No, this BT issue is the biggest one on WM5

No, it's different ones. WM5 uses the "storage" area for your personal data; you now no longer have /storage as it's all in there. The RAM becomes proper RAM, although you can use some of it as a ramdisk with the same loss-of-power issues as WM2003.

That's exactly what I do. I've stopped using the PC installers, there is enough junk on my PC. Just find the cabs for the apps and keep a copy on the SD card.

Not all apps have cabs.. so that might be a problem.
as well as I'll have to make pre-made .reg fixes just incase I'll have to HR.
as for WM5, if I install it, won't I have less free space then ?

You can extract the cabs in various ways. Some exe's can even be opened in winrar.

You can reformat the storage area to 60 meg before the upgrade. Only before though. You don't get a memory slider like in WM2003.
Still, I'm not so sure on WM5 being the best for you. You'd want to have reliable BT and I'm not sure it is on WM5.

So I guess I'll stick with WM2003 for the time being.
I'm ordering an SD slot for the dashboard, as well as a USB connector.
Another Idea I've had is the need for the hardreset as well as reset button.
to which version should I upgrade my rom then ?

sorry to butt-in but, someone had done that before: SD-WiFi & SD Mem Card in parallel on the same 9 pin source: pda sd expansion.
a switch might be of help if you don't want to use the two slots simultaneously.

Yes I've seen that. Its a pretty lame hack if you read it to the end.
there's a better link with larger photo's for anyone interested:
http://homepage.ntlworld.com/david.hutchinson27/pockpc/
also, his project doesnt seem to work at the same time, and I've decided not to go with the switch route.
I'm reading a lot of the SD specs, So there is a very slim possibility I'll be able to get two cards to co-exist (and I would love some proffesional help if any of you guys know more about SD's then I do).
if not, then I'll just make an SD slot on the dashboard..

Speed of SD slot?

I am upgrading from XDA Exec to the Vario III and I was going to buy a memory card at the same time. Does anybody know which class the SD slot is? I am hoping it is nice and fast and supports the ultr high speed cards.
Thanks

I have a cheap card that I got with the phone and a more expensive one (Sandisk UltraII)
Personally, with the Kaiser, I can't tell any difference between the two. Not when transferring files to/from my computer and not when using the actual device.
However if I compare the two cards in my cardreader on my computer there is a world of difference. (The UltraII being roughly 6 times as fast as the generic one I got with the phone.)
I don't know if it's just my phone or ROM but to me it doesn't seem as if the Kaiser can actually utilize the extra speed at all.
Of course, the Kaiser having an utterly slow USB connection doesn't really help either so maybe there is a difference when it comes to usage on the actual device. If so I just haven't noticed yet as the only transfer heavy stuff I do if pushing files to and from my computer which (I guess) might be hempered by the USB connection.

I'm using Kingston microSDHC class 4 card and in phone it is just so slow as generic ones, but in USB reader it's fast like hell

More storage?

Is there/will there be any way to get more than 4GB storage?
Does the phone have USB host support to connect an USB stick?
Is there any Bluetooth/Wi-fi flash reader or USB hub on the market?

Hmm, not sure if it has host support, but wouldnt a usb stick just defeat the whole purpose of having such a small device?
It might be possible to use bluetooth to connect to a flash reader etc, but i don't think windows would have native support for that.
The only other way is to open it and replach the flash chips - but that depends on what package chips they use and what lines they run on the pcb. I'm quetly hopefull.

no it doesnt allow for extra storage to be put on, unless your into NAND stacking...

i don't know how much truth is there to this but check this out:
this copied from: http://www.navigadget.com/index.php/2008/04/26/htc-diamond-specs/
"GPS enabled HTC Diamond’s specs are all over the internets and we thought we’d share this with our readers:

hmm and i don't think they are right ..

the HTC DIAMOND DOES NOT HAVE A MICROSD SLOT!!!

These are olddd specs from end april. I think its safe to say its conclusive there is NO memory expansion slot on the diamond.

I don't think it's correct either. The Diamond has the 4GB internal and no expansion, the Raphael has the qwerty and micro SD expansion and no internal 4GB. Unless they have changed it. Thanks, JASTECH

Mobidapter: MicroSD to USB adapter

This adapter can be used as an alternative for the USB-Host functionality but I was afraid the microSD part wouldn't be long enough to fit the HD2 MicroSD slot.
So I managed to get its microSD part length according to expansys' product image:
The length is only 17mm but the minimum length to get it work with HD2 must be 20.5mm. I used a calliper to measure that.
So, I was hopping anyone would come up with an idea to use this adapter with HTC HD2.
Please notice that the adapter price is £29 excluding the shipping cost so I prefer not take the risk to disassemble it for extending the microSD length if it isn't possible.
Thanks in advance,

that's a very interesting product..

What is it for, are you trying to use a USB stick instead of your micro SD card?
If so, why?

a portable HDD caddy LOL
shame though, the MicroSD port wont put out 5v 500mah
although its probably enough to power a CF/MSproDUO/XD type of reader for example to clear some space on your digital camera card without deleting images (or simply to view them on a bigger screen )

Sometimes you really need work on a USB stick but you don't have access to PC.
Or as quasi_mojo said you can connect a card reader to your device...

Will I be able to play some mp3's directly from a pendrive with this device? Because I have about 25GB of music and I can't afford a 32GB microSD card.

i THINK (i could be wrong...) a pendrive would require more nearer 5volts to work...
opened up my SDcard reader a few days ago, plugged into usb with a 2gb sdcard...it was pulling 3.4-3.6volts while accessing the card, which is damn close to the MicroSD maximum voltage...

Anyone knows where to buy?
There is a shop in the USA, but who knows a shop in europe?

PS Why not attache a harddrive to my Tab

Nook Color option
It would be cool if someone could make a Micro SD socket adaptor (with a usb converter cable) that would allow the ability to connect to and drive a scanner and a printer. One would need the appropriate app designed for it too. A nice option for the Nook Color.

Hi there,
I had the mobydapter here, but it didn't function with my galaxy 7 inch tab. Pity I had to send it back. No function beside beeing very unstable by nearly dropping out of my tab. Oh I forgot it was blinking. ;-)

***MOD EDIT*** shows a Mobiadapter attached to a Galaxt Tab 7 tablet.. Somebody said that this doesn´t work on that Tab... What kinda of marketing.. Argh!

The Mobiadapter no loger exist.
Someone know something like that?
Thanks for support

I need this product for a security research. If you happen to have one, even as used, please message me.

Turn a 7310 into 7300 (3g) possible?

I've found internal sim card readers for P7300 so I was wondering whether it's enough to add that reader to enable 3g in 7310 or the differences between these 2 models is also on the mainboard, due to some chip dedicated to 3g radio...

You've already answered

Damn it
Anyway I'd like to find a way to hardware mod this device in order to insert a memory card holder. I hope there are somewhere on the mainboard tracks and points prepared for a memory card holder connector, although not soldered.

I am also thinking to put inside the tab a microsd reader hooked up directly to the usb host pins of the multipurpose connector.... but I need first to build some confidence

Ok, let's go into the other thread I opened
