Removing the voice prompts is sometimes useful, for example playing in a loud sound system were the voice prompt will be heard in the big speakers, or for you is just simply annoying.
This can be achieved by flashing the decoder with a customized firmware.
Here are the files and instructions.
- New firmware available - SD Model with display Only!
1.- Removes voice prompts
2.- Removes hands free calls interruptions.
- Original firmware - SD Model with display only!
1.- Restores English voice prompts
2.- Restores hands free calls.
2.- Rename file to jl_bt46.bfu
3.- Confirm your decoder Bluetooth ID is M01BT
4.- Power OFF your PT01S, insert SD card on decoder
Dont forget to delete file from SD cause if inserted again it will always try to flash.
WARNING: Do not try to flash this firmware in a decoder other than Bluetooth ID M01BT, it will mess up other decoders!!!!
