active on a disco 3 aftermarket reverse camera?

[Nicool]

hi guys,

I've just got a Sony XAV-AV205DB (double-DIN receiver) installed by a professional on my Discovery 3 (2007, SE model), together with a Mongoose MC304 camera.

When i reverse, it displays the basic distance guidelines (3 levels), which are a feature of the Sony receiver, but that isn't too useful as i have reverse distance sensors.

It doesn't display what is sometimes referred to as "active guidelines" or "dynamic guidelines", you know those lines that get curved as you turn the steering wheel, to predict the trajectory of your car, taking into account how much you are turning.

When i look at my camera's product sheet, the illustration shows such lines:
MC304 - Reversing Cameras - Reversing Cameras & LCD Monitors - Products

The installer told me such dynamic lines wouldn't be possible on the Discovery 3, because it lacked some sort of interface with the steering wheel (i reckon he referred to ABS, but i am unsure, as i was in a rush and couldn't stay to chat).

So asking for your experience: has anyone managed to have such dynamic guidelines on an aftermarket reverse camera on a Disco 3?
Are you aware of the limitation he referred to?
I am having few hickups on the installation, maybe all normal, but i thought i'd ask for second opinions here

cheers
Nicolas

In theory you could tap into the steering angle sensor .

thanks mate!
Would this require a dedicated input to the receiver? According to my Sony manual, it only has:

• llumination control terminal
• Steering control input terminal (as i understand it's for steering wheel buttons if present, such as volume)
• DAB antenna (aerial) input terminal
• FM/AM antenna (aerial) input terminal
• Microphone input terminal
• Parking brake control terminal
• Reverse input terminal (video input from the camera)
• Camera input terminals (up to 2 extra cameras supported)
• USB port
• External input terminal (i think that's for a wired remote)

So i am now doubting that my receiver is actually capable of supporting that feature.

I said in theory because there is no guarantee that the input can be decoded by the head unit so most likely not, the camera will show where ever you are heading anyway so not something i would be concerned about.

Yeah it still works
It’s just that this particular camera is oriented in a way that doesn’t allow viewing the rear bumper, so i’ll need bit of time to get familiar with what i see/don’t see
