A:AnswerGarmin Dash Cam's are designed for the automotive environment and are certified to meet the required international product safety and battery safety standards. It is normal and expected for a Garmin Dash Cam to become warm or hot and remain safe for use in warm climates with full sun exposure.
A:AnswerYes, the cam will disconnect relatively easily from the mount. It can also be updated without disconnecting by using the smartphone app.
It will live feed to your phone but uses WiFi to do so. You pair it using Bluetooth but the live feed uses the Bluetooth connection to set up a WiFi connection between the cam and the phone to handle video.
A:AnswerI've also experienced this. It seems to be an issue with the distance between the devices - it's very limited - only a few feet. I have also had to reset the Bluetooth on my smartphone a couple of times (power-cycle smartphone).
