If you have any valid unlock code for any device, you can get the FID PID RID VID using InfoUC to parse the unl file. The latest version 2.80 is in [Only registered and activated users can see links. ] I don't know if there is anyway of getting the info from the voice file itself, but you could check the threads in the [Only registered and activated users can see links. ], scroll down to 'Garmin Voices & Voices Management Tools'.
