Doesn't work, only thing left to try is the DC to DC step down converter that I ordered. But I'm getting tired of trying to solve this interference.@DexterMorganNL which size of ferrite ring have you ordered for the RCA cable? I have a Suzuki S-Cross with just a little bit of interference on the reverse image (my back camera is grounded on the reverse light wire directly, not on the connector). I think this may help for me as well, but I will wait for your review before ordering
Ps.: Nice review, I have been using Mekede M300s in my car since Apr, beside some small bugs it is working fine.
Have you ordered a DC to DC step down converter as well? The idea was, to convert the voltage from 14V down to 12V.
