GPS-Chip SIRF-III upgrade from Version: GSW3.2.4TT3 to Version: GSW3.2.5TT3

As German site requires to sign-up and other link seems expired, I've found 3.2.5 GPS firmware file uploaded here

Also instructions are a bit vague, so this is what I've done and it worked for me on Rider V2:
- put content of firmware upgrade zip file into empty SD card (I have 5.5120 bootloader so card was 16GB)
- turned Rider on with card in which started firmware flashing
- after firmware finishing flashing (full green line) device restarted and got back on "flashing process is starting" and stuck there, power button wasn't working
- I've removed firmware upgrade SD, put in SD with navcore and pressed reset button via pinhole near charging port
- after this I've turned device on and it worked as expected.

I think that any device running GSW3.2.4TT3 can be updated with GSW3.2.5TT3, if the chip is SirfIII.

Since 28 September 2019, there is no size limit for the SD card (2GB) ,
but a suitable bootloader must then be installed.

the GPS firmware GSW3.6.0 generally (but not always) finds approx. 2 satellites more than the GPS firmware GSW3.2.5,
but the GPS firmware GSW3.2.5 is usually a bit faster with the Satfix than the GPS firmware GSW3.6.0

If you want your GPS to always sync as quickly as possible, choose version 3.2.5,
if you prefer to wait a little longer but get most of the satellites, get version 3.6.0

A NOTICE. Firmware for mobile Tomtom Navi with GPS Chip Sirf 3;
with bootloader version: 5.xxxx and only for this

Caution ! , do not use for permanently installed (also with radio) devices
with the BootLoaderVersion = 8.00xx

For the fixed devices with a different bootloader version such as: version 8.xxxx ,
never, not even once try to carry out the upgrade described here !!!
The upgrade will not be written to the correct location in the Navi, and this will render the device unusable.
We also have no way of reversing the flash process.

the renewed upgrade has the name:
One For All-Universal-Upgrade GSW3.x.x GPS-Chip_SIRF-III

Is this still true?

The "standby problem" has now been resolved (another satellite fix after standby within a few seconds).
QuickGPSfix every 7 days, no longer necessary
