Do you remember which one you ordered? I found one https://www.amazon.com/SimpleUSBPort-Mirror-Dashcam-Adapter-10-pin/dp/B07KZSBC54 that claims to work with Nissan but I can't tell if it would work specially with the Leaf, in my case a 2020 SL+.
Can leaf spy disable the reverse chime on the 2020? I'm hoping to just get a confirmation and not start any discussions on whether or not it should be done. Thanks!
