I have just bought a Blackvue DR650GW – 2CH. Straight out of the box the rear camera did not work. I contacted the retailer who asked me to return the full kit for inspection and diagnosis. Once it had been examined it was determined that the cable was either fractured and / or that one of the centre pins of the plugs was out of alignment. I note that there has been some correspondence on the internet about these cables and wonder why, after all this time, the cable has not been strengthened and more robust connectors used. I don’t have off street parking and so I remove expensive items from the car which entails, of course, disconnecting the rear camera. These cables and connectors ought to be strong enough to cope with multiple connections and disconnections. Why aren’t they I wonder?
