Pioneer IP-bus

[TeamPSI]

I am a Pioneer Car Audio fan since the 1990s and have various pieces of equipment that use the IP bus Communication. From what I can remember, I think it uses CAN to communicate and control the external components or modules. I am not an Electronics expert by any means so I'm asking here if someone knows if it's possible to convert the IP bus connection to something usable by the current Pioneer head units so that newer units will be able to control the old IP bus equipment.

For instance, I'm wondering if the round connector that's used with Pioneer satellite radio module could be somehow used or maybe USB? I don't know that's why I'm asking. LOL
