Signal for parking chimes/beeps?

[squiers007]

Hey everyone, I'm in the middle of an audio install on my 22' GT2 scorpion and had a question. I will be tapping into the factory digital signal at the HK amp and I've located which wires these are (pins 20 and 22 on Connector A), but from what I understand this signal does not contain any of the parking sensors chimes or Navigation prompts. I'd like to retain these if possible and I'm hoping I can also pull them from the factory amp. My hope is that the chimes are contained in the "Amplifier navigation voice" signal (pins 9 and 23) and not withing the CAN signal since there is no way that I've seen to decode this. Has anyone done this successfully before? Thanks.

Nobody has tried to figure this out before...?

From your explanation, sounds like you're doing a replacement of the factory amp rather than adding an amp to replace specific channels. I've only seen one person replace their system with Focal speakers, but I don't remember what they did with the amp.

If I had to guess those navigation voice pins are pre-amp inputs, and to mix those with the audio input you would need a low-level input multiplexer or mixer, then output that to your new amp. Kinda like a DJ mixer. I imagine that "Multimedia-CAN" input probably controls the volume of the navigation voice based on the settings from the head unit, but no getting around that.

So you might have to add something like this that takes the Amp SPDIF inputs and the Navigation inputs to feed to your amp, then you control the input volume from it:

I'm using a DSP that has both analog and digital inputs that I can mix how I want to within the software so no concerns there. I've not found anyone who has successfully pulled the chimes before and I'm thinking at this point that they are in the Canbus signal... which to my knowledge no one has decoded yet either. I think the ARC blackbird can do it, but I haven't found anyone whose used it yet.
