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

Read through the thread, The answers are there, Find the screen calibration tool and rename it to Auto.exe and place it in a folder called N20i (I think, It is written in a post in this thread somewhere) and copy to a SD card, insert into device and restart, When the screen calibrator is on screen you should have USB access, Undo the changes you made, remove the card and reboot again, You should be back to normal now...

thanks you but i read the thread and that trick doesn't work.more to the problem i copied the winceimg.bin from another navman model and updated the device and now it doesn't boot anymore.i think the winceimg for the n20i wich i found is corrupted.i'm struggling with the winhex and the bins i have for N20i.

If the ROM flash failed then only reflashing will fix it, and only the correct firmware will work, Back to scouring the internet i'm afraid...

BTW flashing the ROM only updates Windows CE, It does not fix the reboot loop problem which is on My Flash Disk

That's the weird part cu'z the flashing of navman s50 rom was succesfully but the original doesn't work.keeps saying wrong size.it drives me crazy.and yes i i think i blocked a few google's servers :)).......maybe someone succeded to flash the original or has the original to send it to me.

I've found a few ROM'S by searchibg for the filename of the archive rather than "Navman N20 firmware" I tend to find them on Russian and Polish sites, Google translate works wonders...

hmm....i haven't found a good source.what i found just a few dead download links but i sent a few pm's and i hope soon i'll get my hands on the original and intact rom.at least i hope.thank you very much for your time and if it's not too much to ask for some links or anything of mentioned above

Firmware files can be elusive sometimes.

If I find it, I'll post it.

Thank you for you'r kindness.I wish you the best

yep.....still the same situation.a bricked device and can't find a solution.the problem is the gps it's not mine and i don't wanna buy another one for that guy.still looking.anyone?

I did have a quick look but didn't find anything.
