It's known to work, it's very safe and it's a little smaller than the later firmware version combo which may help with the loading.

You would still need to flash the 465 logo to enable TTS i think, unless your 205W has previously been flashed with the senior 2x5W logo to enable TTS. That can be done later anyway if needed, so baby steps ... try either of the files without the logo.bin initially.
Finally it worked!!!!!PouchX file worked. It upgraded the software and the Updater said upgrade succeeded. I am yet to take it on a ride after the upgrade to see the lane assist. Is their anywhere in the hidden menus to see the firmware has been flashed?

I also did the TTS upgrade using the post you mentioned - [Only registered and activated users can see links. ]
Just did a simulated drive in the GPS unit. Didn't announce the street names. Does TTS not work in sumlation mode or any setting needs to be enabled somewhere?
