剛在TOMTOM官網逛Q&A無意間看到的說明:
GO710需將鈴聲檔案存於SD卡上
來電鈴聲檔案名稱:ringtone.ogg
來電鈴聲格式:Ogg Vorbis, 8000 Hz,16000 Hz 或 22050 Hz.
簡訊鈴聲檔案名稱:smsreceived.ogg
簡訊鈴聲格式:Ogg Vorbis, 8000 Hz,16000 Hz 或 22050 Hz.
官網原文:
Save the ringtone file to the root directory of your hard disk (GO 910) or memory card (GO 710/510) with the name "ringtone.ogg". The ringtone file for incoming sms messages should be "smsreceived.ogg".
Ringtones must use the Ogg Vorbis format with a sample rate of either 8000 Hertz, 16000 Hertz or 22050 Hertz. You should make sure that the ringtone is not too long and test the ringtone to check that it is loud enough to be heard in a noisy car. (原文出處: TOMTOM.com)
