2022 Kia Forte GT2 Steel Grey
I believe it works off the CAN system. You have a high and low CAN wire. Can't blow up the diagrams to tell you where they are.
Could not locate an actual activator, this is why I believe the CAN system actually tells the radio to activate camera. Also believe it operates the power loss nag. Even with power constant on both ignition and ACC wires still have the power loss nag pop up on the screen. I was trying to convert a 2019 5 inch to the 7 inch. Only 2 wires that I couldn't get to work were the CAN because the 5 inch didn't have them in the original harness. The 5 inch has an actual camera detect wire at pin 36 but the 7 inch screen does not have this. The pics above are 2017 7 inch. Connection pin for 2019 7 inch are this....tc0566 - where is the "activation" switch located - in the transmission selector? I.E. what turns on the camera in the monitor when you shift into reverse?
NO volts to CAN..that is a data link between the radio and the ECU. I have seen people put voltage to that and fry it....DO NOT PUT VOLTAGE TO ANY CAN WIRES!Based on what I'm seeing does this sound like It should work with the above pin set. Constant power to camera from pin 10. Ground pin 11. Camera video imput pin 4. Camera video ground pin 3. Once I have that set Can low pin 13 grounded and then by getting the right volts to pin 1b when it's in reverse that is what will tell the radio to switch to camera view.
I found the same setting in mine for the power nag, but on mine it reset to default on every restart. Glad you got it working on yours. Dealer was of no help to me on mine. Just be careful not to power the CAN wires and see what dealer says. Might be easier to use aftermarket camera...or not, depending on if able to trigger with this radio.Yes I got everything working. Gps ,usb and aux jack. I connected pin 33 to power wire and it keeps the settings. Also keeps the battery drain message away. I went into engineering mode and there's a setting to turn that message off and pin to power kept the settings. I just went into the camera type settings and the options are there but it doesn't let me change the type. I may see if it's something the dealer knows about.
