I had that issue with my 650 but not with the 750-2CH. I've been running the 750 now for about 3-4 years and that SD is still going strong. Maybe luck of the draw. It wouldn't surprise me if you switch to a different HD SD...it wouldnt fix the problem.
I've had BlackVue for many years now. Highly recommend. The biggest differentiator (for me) is their parking mode. Best in the biz. It records before the event, not just on impact and after.
For those that have installed the track bar brace, was any alignment work needed? I've seen one video where they stated the steering wheel was not centered anymore. No one else seems to mention it. Thx.
