This is for a 2017.....

 

So, according to the diagram, the reverse signal is the white wire on terminal 16 of connector 'A' located on the front of the dashboard fusebox...

If I helped you fix it, why not...

Your support is greatly appreciated​

Actually, it might already be on the radio connector. Look for a red/black wire, then check that it has +12V when reverse gear is selected (with the ignition on). I originally thought it was only there on navigation head units. But looking more closely at the diagram it seems there is a reverse signal supplied to all the factory radios. That should save you a bit of faffing about at the fusebox.

Thanks guys. Much appreciate. Will update once it gets working =)

 

Finally got it to work. Had to also get a 6v stepdown and retention harness.

 

Ibanezbass671....I have an identical set up, down to the radio apparently, I'm trying to enable my OEM backup camera as well...how did you find the Reverse Trigger wire in the Factory radio harness? I just bought a retention harness to plug the camera harness in the car into my new touch screen...any help on how you accomplished this will be appreciated...thanks!

 

Same here. Bought an Android head unit for 2015 Santa Fe. Unit works fine except for the reverse camera. I want to keep the factory camera, so I purchased a harness but still no luck. If I understand correctly, using that harness should enable me to avoid finding the reverse wire at the fusebox etc. Any insights appreciated.

 

Does the retention harness come with the 6V stepdown? I have the exact same car and trying to do the same thing. I got everything on the stereo working but I have not connected the camera yet, just ordered the harness from Amazon

 

Did anyone else figure out the answer? I can't get the camera to work and was hoping OP would explain what they ended up doing...

The OP hasn't logged on to the forum since July 2021. So I think getting help from him is unlikely.
