For some reason, every dashcam I have installed in my 2012 Honda CR-V has exhibited some kind of high-pitched noise. It first started with a mini 0806 and now I'm having the same problem with a new Viofo A129 Duo. Another CR-V owner on dashcamtalk.com mentioned he was having similar problems. Aside from the A129, there are no other aftermarket electronic devices installed in my CR-V. I've put together a short list of the things that could be causing this issue. Please let me know if I'm missing anything.
- Defective dashcam (unlikely since two different brands have had the same problem)
- Grounding problem
- Interference from something in the CR-V
