Medion P5430, P4425, 4240 & 4440

Postby rongrenfell » Wed Feb 24, 2010 1:39

UPDATE 20101010: Bestsolver (4440) and gbungter (4240) have advised that recently bought devices have a different file content to the versions previously described. This is likely to apply to other models as well. Step 8 has therefore been modified to be less explicit, so as to handle possible variations in the existing text in the file. You might need to experiment a little here, but the correct things to change should be fairly obvious.

Thanks to Douwe for providing this detailed description for getting PocketFMS running on these Medions.

Unlike many other systems, Medion PNA devices only try to run a program from the SD Card if the relevant file on the Flash disk tells it to do so. Therefore the procedure to start the PocketFMS licence-file is somewhat different to other devices.

With this procedure you will be able to modify your Go-Pal 5430 (firmware version K2.5.E1.2) in such a way that it is suitable for both car and aviation purposes.

The same or similar general procedure should also work for the Go-Pal 4425, however it has not been tested on this device. PocketFMS will not work fully on a P4425 with the original firmware version K3.6.E1.4 as this firmware does not allow the software to access the $GPGSA data-string of the satellites. It is therefore necessary to "downgrade” the firmware to version K3.3.E1.4 before following the general procedure below. German Medion users report, that flashing the memory with this firmware does not have any negative influence on the Go-Pal software of the P4425.

According to Schoenf the Medion 4440 can also be prepared using the same general procedure, but doesn't initially work with PocketFMS because the GPS output is directed to a VSP (Virtual Serial Port). As the 4240 is essentially a 4440 without bluetooth, the same is likely to apply to it. This can be fixed as follows (original description in German at w​w​w​.​w​i​k​i​.​g​o​p​a​l​-​n​a​v​i​g​a​t​o​r​.​d​e​/​i​n​d​e​x​.​p​h​p​?​t​i​t​l​e​=​G​o​P​a​l​_​5​.​x​_​F​A​Q​#​G​P​S​.​2​F​C​o​m​p​o​r​t​_​-​_​B​a​u​d​r​a​t​e​_​e​i​n​s​t​e​l​l​e​n)​. You can change the comport settings on the device (COM1 to Com9) from Settings>Program Settings>Info. There is a hidden button in the corner which opens a new "Configure GPS receiver" menu. Setting COM1 on the device is equivalent to setting COM2 in PocketFMS. Important Note: You will need to change the setting back in order for the car navigation to work.


1. Have an empty (formatted) 2 GB SD-Card ready. A 4 GB DD-HC Card may also work. Other users reported good results with the Sandisk and Transcend SD-HC cards. Do not use the high-speed types.
2. Install Microsoft Active Sync on your desktop.
3. Download a suitable icon from Be sure to take the 48x48 pixel format. Rename this icon to “icon_airplane.png” and have it available in a easy to find directory on your desktop.
4. Optional - You may also want to get the CE-Laucher from (free of charge but subscription required). This program, will enable you to access the Windows CE desktop and Explorer from your desktop computer without making complicated resets.

Modifying your Medion.
5. Connect the device with your desktop by using Active Sync. Locate the directory “My Flash disk\navigation\menu\desktop”. In this subdirectory you will find the XML files and Icon.png files, that will compose the main menu on the Go-Pal.
6. Back-up the complete subdirectory “menu” to a safe place on your desktop in case anything goes wrong.
7. Locate the file “SUDOKU.XML” in the subdirectory “desktop”. It will be used as a template to create the required PocketFMS menu file. Copy it to a temporary working directory on your desktop.
8. Rename the copy of the file as PocketFMS.XML, and edit it as follows in a text editor like Notepad:

In the line starting <Execute, keep the same general format but change the exe specification to Storage Card/pocketfmslauncher.exe For example <Execute command="file:///storage card/pocketfmslauncher.exe" /> but note that not all Medions have the word "command", and there may be other differences, so you need to adapt this example to fit the format on your device. A listing of an entire example PocketFMS.XML file is given at the end of this post.

In each line of the form <Icon language="xx">sudoku.png</Icon> ,(xx is a country code) change Sudoku.png to icon_airplane.png

Change any other occurences of Sudoku to PocketFMS.

**Important: Leave all slashes, quotes, spaces, signs, etc. exactly as they are - just exchange the relevant words!

9. Copy the edited file to the subdirectory “desktop” on the Go-Pal.

10. Copy the file “icon_airplane.png” as earlier prepared in step 3 into the subdirectory “desktop” on the Go-Pal.

This completes the modification of the Go-Pal system. Note that the newly created PocketFMS icon will only become visible after inserting an SD card containing PocketFMS (and possibly resetting the device). So don’t be disappointed if you don’t initially find your new icon on the menu.

Preparation of the PocketFMS SD Card and licence file.
11. Start the preparation procedure of the new SD card as described in the PocketFMS manual. This will work straight forward with the 5430. When the SD card is inserted (step 5 of the PocketFMS preparation procedure) normally nothing will happen even after a soft reset. However the newly created icon should now become visible on the Go-Pal desktop after you made a soft reset. If not, you have made an error somewhere.
12. Clicking on the new icon will open the PocketFMS licence file, after which you can complete the further preparation of the card. Note, that you will have to limit the amount of PocketFMS data to about 450Mb in the set-up menu if you stick to the 2 Gb card.
13. Using a SD card reader, copy the complete and original Go-Pal SD card to your working directory on the desktop, locate the subdirectory “Mapregions” and remove the countries you don’t need. Leave the subdirectories as they are, especially the subdirectory “Command”; just remove single countries with the extensions *.psf.
This normally will create enough space to accommodate the PocketFMS files on the new SD card.
14. Copy the reduced Go-Pal content to your PochetFMS SD Card. Obviously you do not need to reduce the number of countries if you use a 4 Gb SD card.

If everything has been done according to the procedure as described above, your Go-Pal will perform both duties by pushing the relevant buttons. Sometimes you may need to make a soft reset to switch from PocketFMS to Car navigation in order to “free” the GPS receiver. Most of the times however it will make the switch without any trouble.
This will give you a very competitive (The 5” widescreen P5430 now sells at Aldi for €100,-!) multi purpose GPS navigator.
