connect CarPC to pioneer HU instead of Navigation device
I have Pioneer AVH-P2400BT as the HU in my car. External Navigation unit can be connected there with proprietary interface. As i have checked that interface have the RGB video signal,
Audio input and communication lines. Idea is to connect CarPC to that Head Unit instead of navigation box.
Use FM/AM/HD Radio of the HU (No need to have additional hardware on CarPC)
No need to have any Front End Software on CarPC like Centrafuse, RoadRunner e.t.c
No need to spend money on touch screen.
You can convert the HU to carPC by simple push the Navi button on HU.
I have one serious problem that i could not find description of communication protocol between HU and NAVI unit.
Any help will be appreciated.
And sorry for my English
