Cable between PDA, GPS and car lighter.

Hi,
I am looking for cable that I could use to connect my JasJar PDA (USB mini port) with GPS (USB mini port) and car lighter. This cable should transmit data between PDA and GPS. Also it should power PDA and GPS from car lighter socket. Look at attached picture for better explanation.
Do you know where I could buy it?
Best regards

Cześć!
Myśle, że nawet jeśli masz taki kabel, to będziesz mieć problem. And there my Polish runs out!
(trans: Even if you had such a cable, you'd still have a problem).
Or at least I would assume so... Even if you made a mini usb to mini usb cable with power spliced in from a car adapter (easy enough to do after all) then you would still have the problem of persuading your pda to use the usb connection for rx/tx gps data, which I would have thought was a drivers problem...
Anyone?

Hi,
As I read on some forum this device can work as USB host and WM 5.0 has many drivers also for GPS devices. Is that true? If it is, problem how JasJar will communicate with GPS is not a problem. The problem for me is that I cannot make that cable myself and I need sombody help.
Best regards

Sadly, this device cannot act as a USB host... I am frankly disappointed that they decided not to implement it, but I guess there always has to be a reason to upgrade to the next model!
I'm afraid I don't know about WM05's support for GPS devices connected via USB, although I think I have read in other threads that people have tried without success to connect GPS receivers to their Universals.
I bought a BT gps receiver to use with mine, and am hoping to cover the cost of that when I sell my IIs, wired gps receiver, cradle etc. One thing that attracted me to the Holux that I bought is that it can apparently be used as a gps mouse if you buy the optional cable - a usb to usb mini that has a curious small plastic junction box halfway along it's length. I assume that there is some form of jiggery pokery going on in there (like swapping the 2 data lines or grounding something ) because I certainly can't connect my receiver to a laptop with a normal usb to usb mini cable.
Sorry I can't help more, but I think you may be stuck unless you can find someone locally who'll chop up some cheap cables for you to experiment with... :?

I am wondering whether if you got a Minu USB to USB B, plugged it into a cheap powered/unpowered hub, the to the GPS would it work?
If it is a cheap hub, when powered, it may have the 5V rails joined, in which case the power might run back to the universal.
However, before testing this, it would be wise to test that the USB can work with teh GPS on its own. If you do not have a mini USB A to mini USB A already and tested (I couldn't see such cables) then www.maplin.co.uk could supply you with the following, which would/should provide you with a connection if it is at all possible:
mini USB A to USB A (Standard with universal surely?)
Female USB A to USB B
Female USB B Female USB A
USB A to mini USB A (Standard with universal)
That is a lot of cables

This cable should transmit data between PDA and GPS.
WHy on earth would you want that?

Once you can prove that the PDA can connect to the GPS that way (one of the posters was not particularly positive on that) then the addition of the HUB would allow you to put the power onto the cable.

Hi Marek,
This is not going to work for DATA but this kind of cable may work to charge both JasJar and BT gps. Log in to www.allegro.pl , find covox in "szukaj użytkownika" go and buy the BT gps with the mini usb port (like G-Space GS-R238) and solder in second usb mini cable into the included car charger .
thats all...

This should charge both....ordered one and am waiting for it, doubt it'll sync though.....

Making Headphones To Fit Mini Usb

I want my in ear headphone to connect to my phone but it uses mini usb, so i have brought a mini usb connector end from a computer shop in town, ive got a old set of headphone to cut up but what pins on the connector do i soilder the wires to???

The plug for the headphones is not a standard mini-USB.
You need a headphone adaptor lead from eBay or somewhere.

I know mate, i need to know what pin on the phone runs the sound then i know what pins to connect my wires to on the usb connector and my earphones.

Custom earphones to usb
1. leave the usb plug alone, the first possible point to grab analog audio is the mic/volume slider combo.
So, either pry open the small mic/volume slider box and solder your new headphone cables into that (make sure to remove the isolating paint from the wires (e.g. by burning),
or open the original headphones and your new ones and just resolder the headphone cables - my recommendation, for usually being easier.
have fun

i remember seeing an article on one of the PPC websites 6-12 months ago when the artemis was still a new device. the article showed step by step instructions with photos and even specified the components required.
unfortunately, i can't remember where i saw it (sorry) but at least you know it exists and with a bit of help from our google friends, you may be able to find it.

Orbit loose USB connector?

Hi all,
Sometimes I have activesync dropping the connection and very rarely get reliable stereo sound through the USB headphones. Charging is fine. How much would I expect to pay to get a new USB socket soldered on, and what repair guys do you usually use (UK).
Cheers,
Nick

[Q] Question new unlocked GSM, USB charging issue

Ok so i ordered my new phone directly from google on tues and i got my phone thursday. I am having some issues with different micro usb cables not connecting and charging it. I know that some of my other cables work with the phone and some dont. Is there something wrong with my phone or did samsung ever so slightly change the cable to make it proprietary? Also the speaker is really weak are there any mods for it or just flashing a different rom is the only way to improve it. thanks for any help guys

Any microUSB cable should work with this phone (I sometimes use my cable from a Huawei phone) - Samsung hasn't done anything to make it proprietary in any way.. How well do these other cables work with other microUSB devices? What exactly happens when you try to use these other cables (e.g. partial connectivity, no connectivity, etc.)

I have a skyrocket and the other cables charge it just fine. with the nexus i am getting no connectivity at all.

[Q] MHL interferes GPS signal?

I want to connect my note 2 to my car stereo via HDMI so I bought a cheap MHL cable for galaxy S3 assuming it works on note 2 as well.
The main purpose of doing this is to see the navigation on the car stereo screen so I don't need to attach my phone on the windscreen. However, every time I connect the MHL cable the phone loses GPS signal immediately. I have tried it at home on my TV, same problem. So does anyone have a genuine adapter from samsung can help me to test if you can get GPS signal with it connected to your TV via HDMI? If it works, I may buy a "real" samsung adapter and through that cable to the trash.

Same with S3

I have exactly the same issue with an S3 - cheapo ebay MHL, as soon as I plug in GPS signal definately drops.
My cable has a standard USB plug for power, and an HDMI plug for the screen and a micro-usb for the phone. To start with I plugged the USB power end into my cheapo £0.99 USB cigaratte adapter from china. Instantly the GPS signal disappeared completely.
I have today replaced the cheap power supply with a more expensive Gifford PowerBolt cigarette USB adapter and now I get more signal, but there is definately still a drop. For instance the phone on its own will Navigate when located near my gear stick, but will not get a signal when plugged into MHL in this location, but I can navigate successfully with the phone on the dash under the windscreen with the new power supply.
I'm wondering if this supply is somewhat better than the crap from China but still too dirty.
Does anyone have any recommendations of an adapter that will give a pure power supply.
The other issue I am having here is that although my power supply can output 1 AMP which should be sufficient to support MHL, GPS, Bluetooth etc and charge the battery, the phone is not detecting this supply as AC so only using 500MA from the supply, meaning the battery drains and eventually runs out on a long journey.
I know this is due to the middle two pins on the USB side of the micro USB on the phone not being shorted, thus telling the phone it's connected to AC and to draw the higher current, my MHL cable clearly does not have these pins connected.
Does anyone know of an MHL adapter/Dock/Cable that has full USB connectivity and MHL connectivity?
Hope this sheds some light, hopefully we can get some suggestions on good quality power sources to cure the interference and a good MHL adapter with every pin connected to the phone to allow for AC power mode with MHL.

We must be using the same product. My one comes in red cable. Actually, I really like the design cos one single cable solves all issue: charge+HDMI. If I use the genuine Samsung adapter, I have to connect both HDMI cable and USB charging cable.Now I use the aluminum foil from my kitchen to wrap all three ends of the cable and it makes the GPS signal a little bit better. I have ordered some ferrite core clips from eBay hope this can solve the problem.

Stupid GPS!!

Any update on this from your end? Did the ferrite core clips work? I have found some more info that this could be caused by the fact the HDMI do signal is grounded to the external lcd display, which in turn is grounded to the cars chassis (either through wires in a harness or directly) and then the phone is also grounded to the power side of things, and because both are grounded to different points on the car this creates ground potential difference. I don't really know too much about this but am told that this will almost definitely interfere with the signal. I have been advised to ensure the lcd display and the power cigarette adapter are grounded to the same point on the car. So I have hooked up a cigarette lighter socket behind my LCD and then grounded both the LCD power and the cigarette socket to the car radio harness at the same point then plugged in the power adapter into this new socket, unfortunately this has not made a difference. The next step I am advised is to ground them directly to the car chassis to achieve a better ground connection.
The problem still could remain due to the fact the circuitry in the in the lcd may cause resistance and cause ground potential difference regardless of both the phone power and the lcd power being grounded to the same point on the car.
I am wondering if connecting the ground of the hdmi port on the lcd directly to the chassis whether this may help?
Do you understand any of this? Does it make sense. Doing my head in!!!
If your ferrite cores helped let me know or if you have found a better MHL adapter that would also be good!!

No, unfortunately the ferrite core clips don't work. I cannot find any better solution than the aluminium foil wrap now.

any solutions?
hi all,
I have the same issue with my S3 and MHL that I got from Samsung.
When I just connect to MHL I see instant GPS signal drop and also data GPS/LTE drop as well
Any ideas how to solve this issue?

Were you ever able to your signal issues? I just installed the x8500bhs and im having signal issues as well.

yes, I solved this issue by replacing black 1.0 MHL with new white 2.0 MHL I got directly from Samsung.
Samsung tech told me that for 1.0 MHL it is expected to cut signal when it's in HDMI mode as TV doesn't expect any GPS
