Mio Transfer Hack

For a lot of actions described on this site you might need Mio Transfer Hack. I think this program is an essential asset for altering / adding / deleting and copying files on your device.

Install Mio Transfer on your PC. It is on your DVD. Then copy mio transfer hack.exe into the install directory. Now you are all set.

Download Mio Transfer Hack: for C210 / C510 / C710.

Alternative link:MioTransferHack Version


Mio Transfer Hack C250 for C250 / C220


Turn your device on before connecting to your pc through the usb cable.

Where and how to store new maps / voices / languages

In order for extra maps / voices / languages to work on your device you have to copy them in one of the following directories:


 \Storage Card\MIOMAP\MAPS\

 \Storage Card\MAPS\




 \Storage Card\MIOMAP\VOICE\

 \Storage Card\VOICE\




 \Storage Card\MIOMAP\LANG\

 \Storage Card\LANG\



Ofcourse you can also copy your maps / voices / languages directly on a sd card using a sd card reader.  Just make sure to make the correct directory first.

After copying do a softreset and off you go.

 Back to Top  

Deleting unused maps / voices / languages

Go to the directories as described  in the topic "Where and how to store new maps / voices / languages" using Mio Transfer Hack.


Highlight the files you want to delete. Make sure you selected the right files. Click on the delete button located just above the 2 windows, the second from the left. You can also push the delete button on your keyboard directly.

Another method is deleting your files through a card reader. Ofcourse this only applies to files located on a sd card and not your flash disk.

How accurate are Mio maps? / Where to report map errors.

Mio products use Tele Atlas maps. Tele Atlas maps are very detailed and even the smallest roads are usually captured.

Wrong route advice is possible:

  • because route calculations are made to match your route calculation favorite choice (fastest, shortest, economical, etc...), with the available roads on your way and their 'grade' in the maps database (from highway to tracks). In some rare and particular cases some roads are not set with the actual grade because of speed limit modifications, road works, addition of traffic lights.
  • traffic situation changes constantly in all countries. Tele Atlas constantly updates its map data but due to the huge amount of kilometers to be monitored, not all roads can be surveyed (this means checked in reality) at the same time. The main roads are surveyed first. This means that mistakes may still appear for a while on smaller roads in map data.
  • not all countries have yet been captured with the same amount of details. If you are interested in a particular area and would like to verify if it's included in map data or not, you can browse to Mappy (this website uses the same Tele Atlas maps) and enter your address. If the area is covered, it will be shown on Mappy. If not it means the area you are looking for is not covered yet in the map data.

Since the map data belongs to Tele Atlas, mistakes in the database cannot be updated by Mio. Errors can be reported via the link: Tele Atlas MapInsight. Follow the link and locate and define your problem.

If you use your desktop computer's SD card reader to copy the maps to an SD card, make sure to copy it into the right folder.

In the root of the SD card, create a folder named MioMap. In that folder, create a subfolder named Maps.

Copy all the maps there and your device will find them.

Detailed procedure :

Note: it is not possible to copy maps on a SD card present in the Mio device. The SD card must be placed in a SD card reader.

  1. Insert the MioMapV3 DVD in the DVD-drive of your PC.
  2. Insert the SD card into your SD card reader
  3. Choose your language for the installation.

How can I reset my C710?

When your device is not working properly, you can reset it.

Always try a soft reset first (pos 4 on picture). This will only reset the software. To perform a soft reset, use a fine pointy object to push the little round button on the bottom of the device, between the earphones connector and USB port.

If the soft reset did not solve your problem, a hard reset (pos 5 on picture) might. It resets all software on the device. To perform a hard reset, put the off/on switch on the bottom of the device in the off position and wait for a moment. After that, put the switch back in the on position.

How to silence or restore the click sound in WinCE (desktop)

You will have to do a registry change using regedit.exe.

Look for the following line:

value = 0                means screen clicks are off.
value = 1                means a soft click.
value = 00010002     in hex is the loud click.

A registry editor can be found here:

Mobile Registry Editor is an application that can be used to edit the registry of your Pocket PC or Smartphone (Windows Mobile device). With it you can remotely edit the registry using your desktop keyboard and mouse as opposed to using your stylus/keypad on your PDA or phone. It's built as a Windows application which has been modeled after Regedit (with a few extra features such as favorites, value size, column sorting etc...)

It has been tested with my Pocket PC and Smartphone on Windows XP/2000 and requires the .NET Framework 1.1 to run.

New features in this version [1.1]
  • Create keys and values
  • Delete keys and values
  • Rename values (thanks Pavel)
  • Copy key name to clipboard
Download Version 1.1

Remark: Mio c310x Windows CE 4.2 has his own built-in regedit.

           Location: "\My Flash Disk\Utils\Regedit.exe"

How to improve sound on Bluetooth handsfree function (C510E / C710 / C310)

Some people complain about the sound when spoken to through the Bluetooth connection.

On the bottom, to the right, position 6 in the picture, the very small hole is your microphone. In your PNA car holder  there is also a small hole on the same spot. When you click your Mio into the car holder the audibility for the people you talk to decreases considerably.

So what can be done about that?

Someone on the Dutch, alias jaspernl, had the brilliant idea to modify the microphone hole of the car holder and drill a bigger hole of approximately 4,0mm. (Original about 2,0mm). Mind you, we are talking about the car holder and not your Mio device.

The modification has been done by several people and the audibility has improved considerably.

I will take no responsibility if you do this and something goes wrong. But drilling a little hole is not rocket science. I did it myself also. There are also some pictures on the link below.

How to restore my missing "Track Options" button after Miomap update January 18th, 2007 for C510(E) / C710 and C310(x)?

The track options button has been removed by Mio in the latest update.

Why? It beats me, but if you want it back these are the 2 methods.

A] install another which already has the button. (see datazip skin page for instructions)

B] Hack into the "func_tracking_320_240.ui" file (see explanation below).


First of all download the file from your device through Mio Transfer Hack or ActiveSync.

1] Unzip your
2] Find func_tracking_320_240.ui in your directory ui_mio.
3a] On a C510 / C710 put a ";" before the line "runif vPNA 1 'btn_track_options.hide'" with an editor like notepad.

3b] On a C310(x) find this line and remove the word "hide" near the end:
<BUTTON uib_track_export x=133 y=200 text= " Export " bmp= " btn_bott65.bmp#3 " align= " CENTER " fontsize=12 w=58 valign= " CENTER+5 " fonttype=buttonlabel1 onrelease=' TRACKING_EXPORT lb_tracks' hide>

4] save the file.
5] re-zip your data file back to
6] copy back to your device.

Your button should now be back again.
