Hi guy's i really appreciate your help i have been serching and found a post that says i can flash nav if i have winceimg.cks and winceimg.bin
and as i could sync ok before i tried Fatboyfun's program it might help me as the experts can i have your thoughts and if the files are obtainable.

Hi Guy's just an update found n40 files that can flash n20 and now have stable boot but because fatboyfun instructed me to rename nav program
it cant load far enough to let me sync so now my question is can i put something on sd so i can sync and undo the changes thanks.

Normally on navman/mio's auto.exe in the root of the storage card is launched instead of the original application, rename the screen calibration utility and try.
Also try creating a folder called 2577 and put autorun.exe in (renamed screen calibration tool)

Use the screen calibration tool as it seems to put Windows on hold while it's active.

All navman devices with AppStartupSec.exe look for a file on the storage card before running the original, Also try Downunders suggestion above.

I find that you can explore the device with ActiveSync before it says it's connected, and the Window doesn't close like with USB mass storage devices, It may be enough to get in briefly and make the change.

Hi Fatboyfun thanks for reply tried first two suggestions no go and i cant explore in activesync because until it connects the tab is greyed out
or am i doing something wrong

Go in My Computer and try opening My mobile device or similar, You'll probably just get a blank page, let it do a few reboot cycles and see if it gets enough of a connection to browse.

The auto.exe file may need to go in a device specific folder. try N20, N20i, etc

I'm not at a pc atm but i'll have a search later.

Hi Fatboyfun i hope i haven't worn my welcome out because i am still struggling tried all suggestions so far no go but i have found this.
Yes, Navman is a MiTAC's brand as Mio, but it behaves totally different, if you want to get it started from SD-card. Probably you have to create at SD-card a special folder and put in this folder a "Auto.exe", that will start an application with which you can access the flashdrive of your Navman, e.x. CeCommander. What the special folder's name must be, you derive from file "source.txt" (in your back-up) in line "Software".
Here is what is in my source.txt.

I have a full backup in Stg format and have got this with STGView can you tell from this what SD should be called also can't seem to find CEcommander thanks for your patience.

No-one outstays their welcome here

Right the file you want to look at (From your backup) is app_startup.txt
Open this file with notepad and scroll to the bottom
You should see something similar to these lines...

sdcard_runExecutable(SmartST_CE - Run()): CreateProcess(\Storage card\TATA_400A\auto.exe) failed, error 2
sdcard_runExecutable(SmartST_CE - Run()): CreateProcess(\Storage card\Default\auto.exe) failed, error 2


I've highlighted the important bits, Yours may be different.

EDIT: Total Commander here... 2765

Hi Fatboyfun Thanks for info i am on a steep learning curve i have managed to get original firmware installed it and have got sync back but it doesn't have software i presume only bootloader so i restored back up and am back to legal screen with calibration error so still don't know if it is software or screen itself

I'm still thinking it's a hardware problem, But the next thing you could try is a full unlock, ie boot to a desktop, If you think it's worth it, I'd say we tried a couple of things, neither of them worked and it's an old device so prob not, FYI I'm getting a headache from trying to update a Navman S30 which has similar specs to the N20i.

Hi Fatboyfun i am using this as a project and really appreciate your input i now know that your calibration exe will load from sd if its in a folder N20 and renamed auto.exe although it just keeps repeating over i press the crosshair and it goes to each corner then back to center never completes .I have tried to load commander from sd but it only stays on screen for about 2 seconds the loads legal screen so i can't try the buttons any ideas why it should quit so quick when your exe stays

The screen calibration tool puts Windows on hold in the background when it's active whereas other programmes don't. When i get home from work i'll post the official unlock for this device.

[Please Register or Login to download file] is the official unlock for the Navman N20

[Please Register or Login to download file] page explains how to install and configure, Follow the instructions at the bottom of the page entitled Installation Navman iCN- and N-Series.

Reboot the device, It will now boot to a blue desktop with a Start menu, The first thing you need to do is try to calibrate the screen using the Windows CE control panel, Tap Start-> Settings-> Stylus-> Calibration Tab-> Recalibrate
The stylus option is not installed on every device, If not then install Total Commander and run the Screen Calibration app manually.

Things you need to know...
The WinCE core installed will have been stripped of everything not necessary for the SmartST_CE application to run, This means that other applications may not work because they're looking for dll's that are not there, You can usually place the required dll's into the applications directory.
You can place applications onto the SD card and make shortcuts to go on either the desktop or start menu.
Shortcuts are easy to make... I'll use the Total Commander app from above as an example.
Open Notepad on your PC...
Type the path to the application as it would be on your device enclosed in quotes...
"\Storage Card\MobileNavigator\MobileNavigator.exe"
Count the total number of characters including quotes and spaces...
"\Storage Card\MobileNavigator\MobileNavigator.exe" = 51
Arrange the information like this...
51#"\Storage Card\MobileNavigator\MobileNavigator.exe"
Save the file as Name.lnk (.LiNK) Not Name.lnk.txt
Windows on your PC will hide .lnk

Place the newly created shortcut into either the Programs directory if you want it to appear in the Start menu or the Desktop directory if you want it on the desktop.

Hi Fatboyfun sorry its been a long time i have tried your sugestion i can get the screen but because the calibration is out the start button wont work so im stuck again .Just more info i have noticed on the back of the unit it says Windows CE Core 5.o.

It must be a hardware problem with the digitiser, Placing programme shortcuts into the Desktop folder will give you a bigger icon to tap, but if you can't calibrate the screen there isn't much else you can do.

Windows CE (WinCE) 5 is a common operating system for these devices along with WinCE 4.2 and WinCE 6.

'i know it's been some time since the last post but please if can someone help me cu'z i've got the exact same problem.N20 with the same loop problem cu'z i've renamed the original SmartST_CE.exe from flashdisk.I've found the wince.img but when i tried to flash it gave me some size error.....any ideea,suggestion would be appreciated
