My old sony nv-u53g device map is not uptodate and I think there is no new map for sony nv-u53g.If so which is the best application I can use in sony.

I've no personal experience with Sony's, But i do know they run iGO 8/Primo ok, BUT you need a device specific unlock to access the GPS hardware, Once you found and installed the unlock, it's easy to get iGO working

EDIT: Because i'm nice i found the Sony unlock, And also modified it to run my SimpleLauncher app.

1, [color="red"][SIZE="3"]MAKE A FULL BACKUP OF YOUR DEVICE!!![/size][/color]
2, Rename the original nav-u folder to something else, ie, nav-u2.
3, Copy the new nav-u folder from the attached archive to the internal memory.
4, Copy your choice of navigation app to a M2 memory stick type memory card (Typical Sony!)
5, Start device and use the file explorer to point to the new navigation app executable on the card.
6, Tweak the new app to run like on your other device.

As i know this navi is with M2 card, you need one from 8 GB and map is dvd für becker traffic assist v3.0.

so do I need to unlock the device first ? if so how to do that ? Any application available ....

See post #2

HI , I stuck with this step, 5, Start device and use the file explorer to point to the new navigation app executable on the card.

I coudnt point out the iGO.exe file IN M2 card. Its not showing up

Sometimes it helps to read.
That is the unlock, which you need to perform first: nav-u.exe

I have 2 folder in sony now. 1. nav-u1 and nav-u both folder contain nav-u.exe file ,which one I need to run ?

hi, The message I am getting is

Error

Window 'sonyappMan' could not be found
Line 3 ( \mounted volume\sony\nav-u\nav-u.mscr): close("sonyappman")

Sony can be a pain in the @$$ sometimes!

Open nav-u.mscr with Notepad on your PC and add the line...

ErrorLevel ("Off")

To the top of the text, Save and try again.

oh!! God its really pain in the @$$ .

now its showing,

Error
No existe ese dispositivo

According to Google translate that means No such device

That is not a Mortscript error??? Poss Tooldevice.exe/Testmode.exe?

Is that in a WinCE style error dialog box?

yes,........

Ok i confirmed under emulation that the error is related to ToolDevice.exe

Some Sony's need a slightly different script, so replace...

RunWait(SystemPath("ScriptPath")\"ToolDevice.exe","off 18")
RunWait(SystemPath("ScriptPath")\"ToolDevice.exe","off 15")

with

RunWait(SystemPath("ScriptPath")\"ToolDevice.exe","off 19")
RunWait(SystemPath("ScriptPath")\"ToolDevice.exe","off 17")

...in the nav-u.mscr script.

no luck... the same error
