No, you cannot record audio with the Garmin DriveAssist 51 in all countries where you plan to use it. There are some important legal considerations around audio recording:
Consent Laws
Many jurisdictions have laws requiring all parties to consent to audio recording. Recording audio without the knowledge and consent of all parties may be illegal in some areas. It's your responsibility to understand and comply with applicable laws where you plan to use the device[1][2].
Proper Disclosure
If audio recording is permitted in your area, it's generally advisable to disclose to passengers that the dash cam has audio recording capabilities. Placing a visible notice in the vehicle is one way to provide this disclosure[2].
Disable Audio if Needed
If you have concerns about the legality or ethics of audio recording in your particular circumstances, you can disable the audio recording feature in the Dash Cam Settings menu[3][4]. This will record video without capturing audio.
In summary, while audio recording can provide useful context, it's important to be aware of and comply with relevant laws and privacy considerations in each location where you use the device. Disabling audio recording is an option if you have concerns about its use[5].
