Friday, I drove with the v1.3 logging/beta firmware installed but logging disabled per a suggestion from VIOFO. The A229 Pro worked well during the 3 hour 30 minute drive (mixture of driving and parking mode sessions).
The BlackVue DR970X-2CH is the dash camera that had "HT" (high temp) problems. During the last parking mode session (about 3 hours into the trip), the DR970X started showing "HT" in the status line. When I returned to the car and started driving, the DR970X returned to normal recording mode for about 1-minute and it then shut itself down for about 13 minutes. The DR970X powered itself up again once it had cooled down. The temperature in the passenger compartment was 112F/44C when I returned to the car and started the engine and AC. The outside temp was 86F/30C. So far, with the updated 1.3 firmware installed, the A229 Pro 2CH (rear) dash camera has survived the three most recent driving trips in the heat.
A second VIOFO A229 Pro 2CH (Rear) installation in my wife's car had what is suspected to be a thermal shutdown event take place. Last Wednesday, she drove her car to work and parked outside in the employee parking lot. It was a warm day with high temps in the lower 90sF. At 12:00 PM, the A229 Pro shut itself down. That A229 Pro had v1.2_240227 front and v1.0_231207 rear firmware installed. VIOFO recommended I install the same same 1.3 firmware versions that I have installed in the test camera in my car into the cameras in my wife's car. I installed those firmware updates into the A229 Pro 2CH in my wife's car. She won't drive the car until Wednesday to see if it made any difference. That day is forecast to be warm/hot one as well.
