Unlocking Mio C310 and C210 for Navit
This is a tutorial for unlocking Windows CE devices in order to have them run Navit. For instructions on how to run and configure Navit for WinCE, please refer to the Windows CE page. Mio C210 and Mio C310 devices run Windows CE 4.2, and can be unlocked to execute any custom Windows CE application, including navit.exe.
First make sure you can stat on an SD card
First, you will have to make sure that you have an SD card with sufficient space to store unlock programs as well as the navit files. You will also need to test that your device can startup on the SD card. For C210 (and maybe also C310), SD cards of a capacity above 1 GB are likely not going to work, unfortunately...
Download unlock scripts
On Mio C210 and C310, you will first need to unlock your device. To do so, I used the C310Auto.zip package available at: http://www.gpspassion.com/forumsen/topic.asp?TOPIC_ID=75889 This package was initially written to unlock C310 devices, and should work out-of-the-box for C310, but can also be adapted to C210 (see posts by tweakradje at http://www.gpspassion.com/forumsen/topic.asp?TOPIC_ID=99520). Download the C310Auto.zip file and unzip it to your SD card. For C310, just try to run from the SD card. For C210, you have to adapt it using the following process (adapted from the procedure writeen by tweakradje on the gpspassion forum):
- Rename C310Auto.exe to GOCE.exe as explained by tweakradje. Indeed to C210 device will look for GOCE.exe on the SD card when factory reset is initiated and run it, so we need this exact GOCE.exe filename for the startup script to work.
- Rename C310Auto.c31 to GOCE.c31 as explained by tweakradje. This file is a script file used by GOCE.c31 to perform automatic actions at launch.
- Adapt GOCE.c31 for the C210
Note: on C210, to initiate a factory default reset, insert your SD card (with exe and c31 scripts) when device has no power, insert the power supply (USB or batteries) then long press (roughly 5 seconds) the On/off button until the power LED switches from green to orange. short Rxxxxxxx message appears (black on white), and the orange welcome screen of Mio appears. If the screen turns off after the Rxxxxxxx, try again a long press (often, when changing the SD card, the startup from SD only works at the second attempt) You should get the desktop showing off, with a list of icons displayed on the screen. This means the unlock is working!
Unlock directly at factory config reset
The .c31 scripts above perform a customization of the device at factory default, then reboot the device wiht the new config in order to get the desktop running at each boot. I have no battery in my C210, and restart does not work well on my C210, so I prefer to avoid the reboot and directly get the desktop running at factory default reset. Thus, I adapted the .c31 script, not only to prepare the desktop for the next reboot, but directly to make it available straight on factory default config. On the C210, in order not to loose the desktop once the c31 script has finished, we need to kill a pending process called Oscar90ST.exe. We will do this automatically in the .c31 script by using MortScript utilities (search on the Internet for MortScript.zip downloads - I used MortScript-4.11b5). I only use the executable called killproc.exe</tt, located inside the <tt>bin\PNA folder of the MortScript archive.
Allow use of device unlocked at factory reset on C210
I slightly adapted the procedure written by tweakradje, and I started directly wigth C310Auto.zip: - First unziup C210Auto.zip to a SD card (the C210 device does not handle all SD cards, so first make sure it recognizes yours, SD cards of a capacity above 1 GB are likely not going to work, unfortunately). - I renamed C310Auto.exe to GOCE.exe as explained by tweakradje. Indeed to C210 device will look for GOCE.exe on the SD card when factory reset is initiated and run it. - I renamed C310Auto.c31 to GOCE.c31 as explained by tweakradje. This file is a script file used by GOCE.c31 to perform automatic actions at launch. - I adapted GOCE.c31 by adding the following at the end of GOCE.c31: ``` ```
Test factory reset on a SD card with unlock
Try to perform a factory default reset with the SD card inserted in your device, you should see the desktop and the default Mio navigation should not start automatically anymore. You will be able to run it using the Mio Map icon on the desktop.
Follow the instructions on the WinCE page. Once your navit binary is on the SD card, you can run it by clicking on the CEcmd utility on the desktop, navigate to the \Storage Card\navit folder, and execute navit.exe Once this is working properly, you can add navit to the desktop icons for a quicker launch, by adding the following line in the .c31 script ``` ```
