Don't get a new screen. Did you try a factory reset and setting up the device again?

Or put it in developer mode, where you can choose your model manually:

Try this :

create a file:

\VwBrandDevice\Settings\UserSettingsDevMode.default with notepad



with contents:



Code:
<?xml version='1.0' encoding='iso-8859-1'?>

<Settings>

    <Active>1</Active>

</Settings>

make sure it's .default

then create a file called branddevice.reg and put it to the root /.

reboot and then you maybe able to manually chose your brand/skin. (All settings (route profiles, last targets...) will be lost)
 
ECO Perf Switcher

TOOL:


This is a tool to quickly switch between Performance and ECO Trip:
Extract zip, then copy the folder to the internal Storage /Apps/ .
In addition you need edited Watchdog.ini files otherwise your device will just reboot.

Hi mate i'm trying to bypass the performance mode but it keeps saying to put it in the car that it originally came from which i dont have as the garmin is second hand.

Is there any ways to bypass it now? i'm also looking into reversing the device but can't find anything with 'performance' in the usershell.

I found a method...

-Create an empty file in the root BrandDevice.reg to reset the pairing on next boot;
-Also create a file VwBrandDevice\Settings\UserSettingsDevMode.default:

<?xml version='1.0' encoding='iso-8859-1'?>
<Settings>
<Active>1</Active>
<VehicleIdentificationNumber>WVWZZZAAZFZ123457</VehicleIdentificationNumber>
</Settings>
