Thank you for the fw link. I believe I have the correct file.
As for my question number 2, Was wondering if after adding features, would Garmin firmware update remove them, if applied?
I have not opened the unit yet but was curious if there were even a microphone to be able to use the ASR? Garmin Manual covers 24xx and 25xx and quotes "Voice Command is not available on all
models, or for all languages and regions."
