Can someone please tell me the difference between ASR and ASR2 files? The 11 files (ASR for 3490) have been placed in SD:\Garmin\ASR. But on accessing Voice Command the message "Voice Command support is not available for British English". I can see only a ru_ru.srd file in .System\ASR on the device. Do I need the "en_GB.srd" file? - Where do I get it from? Any advice on where I begin please.

TIA
