Hi
I'm using BMW advanced car eye dash cam for my car from year 2016.
Why I bought it: I know it's not a good solution and really have a high price and low quality, but I MUST bought it when I bought the car, all the BMW dealer in my china location selling the car with an additional/optional part package, so I just selected this one
I want to know how it works for parking mode and driving mode, after i understand it, maybe I can select another dual channel dash cam to replace with it and continue using the power cable from the car.
current testing:
I just pull out the bmw advanced car eye from the car to my desktop for testing.
it have 3 wires for DC 12V in, from some forum info, it maybe :
1. GND
2. Battery
3. ACC+
I'm not sure the wire order and info in the car eye device, so I take out all the screws from the advanced car eye and directly connect it to an external DC 12V Power.
test 1:
1. connet to GND wire 1 to DC 12V [-]
2. connect to wire 2 to DC 12V [+]
result: car eye can power on and startup , then switch to parking mode, video recoding can works well in parking mode, so the wire 2 should be Battery, as I only connected two wires from external power
test 3:
1. connet to GND wire 1 to DC 12V [-], no change for this wire in test 1
2. connect wire 3 to DC 12V [+]
result: care eye can't be power on and can't startup anymore, seems the ACC+ and GND can't startup the car eye dash cam ? is there any additional setting to power on it in normal driving mode on desk ? the external DC 12V voltage is not enough?
I'm a newbie to it.
in fact, I also did some testing in my car with multimeter, seems the wire 3 and GND have 12V power, but it still can't power on it. I will try to check and confirm it tomorrow, as car is parking outdoor, it's raining all day
Thanks
