Holux GPSslim 236 charging problems

Hi I have a Holux 236 paired with my M3100 PDA. All works well, except for a problem with in-car charging. The Holux charges fine in the car with the supplied mini-USB connector. The Holux charger does not though charge the M3100. I bought a mini-USB Y cable to charge both. It charges the M3100 fine (through either connector) but hangs the Holux so I have to take the battery out to reboot. There seem to be two possible reasons: I found the following on a forum, "We measured voltage coming from different charging cables. Both USB-miniUSB cables for our two GPS's has the same output (pin 1 +5V, pin 5 ground). Both RJ11-miniUSB cables (for our two PDA cradles) also has the same output, but the 5V and ground were opposite (pin 1 ground, pin 5 +5V). It explains why cable didn't work with Holux GPS's and worked with our PDA. It looks like the PDA might have a built-in rectifier so you can charge it either way, but Holux model doesn't." I am not sure about that. I think the problem may be to do with pin 2. The Holux spec notes: A/1 = GND B/2 = NC C/3 = +DATA D/4 = -DATA E/5 = +5v I think the PDA cables have pins 1 & 2 linked - telling the phone "This is not a USB power supply" so the phone charges the battery at its maximum safe rate. I think grounding pin 2 causes a problem for the Holux, despite it noting pin 2 "n/c". I have thought of trying to disconnect pin 2 inside the Holux to see if it fixes it but it would not be easy without risking damage. Can you throw any light on this? Thanks in anticipation Michael

Is there anyway to get a bluetooth phone and bt gps to pair if they won't communicate with each other

I have on occasion been able to get my NVM 4070 to connect with my phone. I have tested several different phones with this GPS. I noticed that if you are using a smartphone or pda it has trouble connecting. However, if you try and connect a basic phone, like a Motorola Razr, it has no problem.Overall it is a frustrating process that involves quite a bit of superstitious behavior, on my part, to get the devices to connect. Try restarting both of them.

Once you actually get them to connect, good luck. Like I said, I am able to connect mine, but usually once I leave my car, I have to start the pairing process all over again.

Pin navman handhelp pc will not work off battery

Try holding soft reset for a couple of minutes whilst charging. If this does not work leave pda charging with hard reset switched off BUT all data will be lost. Then move hard rest and if you are lucky the green charging light will start flashing and you can switch on. It sounds as though you have flat battery and if left too long restarting becomes very difficult as the motherboard cannot start the recharging process while the pda is switched on. This is true even with new batteries which can be supplied flat if old stock.
Even liquid damage is unlikely as there are so few exposed connectors. I have not tried it but gently drying motherboard with a hair drier on gentle setting and cleaning battery connector and screen ribbon cable before assmbling might work. Treat both connectors as being etremely fragile although they are more robust than you might think. But treat them with extreme care as repairs to them would be more expensive than the value of a working pda.

Go to the Holux support website at:

NOTE: All quote marks are added by me for emphasis only.

Under the "Select products Catagory" dropdown choose "GPS Receiver/Data Logger".
Under the "Select products series" dropdown choose "Mouse Type GPS Receiver" and

click on Submit. A new page opens showing various receivers. Scroll down to the GR-213u

GPS Receiver and see the one called "GR-213u Driver Program-Vista Driver". It is of a type

of file compression called "rar" which may require a unzip program. I use a free program,

"Secure Zip for Windows". Click on the little yellow box at the far right of the "GR-213u

Driver Program-Vista Driver" line. It will be labeled "9618869.rar". Save the file.
It should be found by clicking on the Vista START and then your user name & should be in

the "Downloads" folder as "9618869.rar".
Creat a new folder for the actual unzipped file by clicking on the the Vista START Icon

& then "Documents". Click on the "Organize" tab & then on the dropdown "New Folder".
Name the new folder "Holux Vista Drvr" & then open it.
Now back at the "Downloads" folder open (Unzip) the "9618869.rar" file. Copy the new

folder "GR-213u Driver Program-Vista Driver" to the "Holux Vista Drvr" folder you created

in "Documents", so that you can later delete all those files that may have built up in

"Downloads"folder from doing lots of downloading.
Open the "GR-213u Driver Program-Vista Driver" folder & see the setup file

"PL2303_Prolific_Vista_3301.exe". The size should be about 2724 KB. Open it to start the

driver install. Now you are almost done.
After Vista has done its driver install, go to "Control Panel" & open "Device Manager".

Now plug in your Holux GR-213 & the "Device Manager" should now show a new entry

called "Ports (COM & LPT). Click on the little + sign to expand it & you should see

"Prolific USB-to-Serial Comm Port (COM#)". The # represents your Comm Port number

used by the Holux. Right click on "Prolific USB-to-Serial Comm Port (COM#)" & click on

the dropdown "Properties". Click on the tab "Port Settings"at the top of the "Properties"

window. Change the value in "Bits per second" from 9600 to 4800 & click OK.
Hopefully you have installed the Holux Utility "GPS Viewer" with a shortcut on the

desktop. Open the "GPS Viewer" & click on "Scan". A new window "GPS Scanning" opens

showing GPS found at the same Comm Port # that shows in the "Device Manager". Click on

OK & the scan window closes now showing the same Comm Port#. Click on "Open GPS" &

then on "Cold Start or Warm Start" & all the satellites found should show up. You can close

the "GPS Viewer" & all the other open windows. If all went as described any software you

used with Win XP using GPS should work OK now with Vista.
Now run your software (MS S&T or whatever) & make sure its GPS Settings show the same

Comm Port# as in "GPS Viewer" & baud rate of 4800.

Cant get the menu display on my pin 570

maybe there is no memory caused by a flat or stuffed lithium battery or battery charging circuit in the pin 570.
leave unit to charge for 24 h
if the battery still dosnt charge because it is over discharged, then you may be able to push some charge in it after the battery is unplugged, after opening the case, and removing the circuit board.
