Thread: 2006 Audi A3 2.0 TDI. Symphony II PCCAR : OEM Indash Screen Prototype. Full pics!!

HOLY S***!!!!!!!!!!!!!!!!!!

once this project is done, and you have the knowledge of it fresh, any chance you would be willing to build something like this out of a ford radio??

Hi BlueOvalMacMech.

It would be hard. My project is now about 750 Hours of work (project started in march) and 3000€ of investment in research/development. It takes all my free time.

Fore sure, I have learn a lot with this project. I learnt how to hack a protocol of communication (the one of the indash Lilliput), how to develop and program PIC based circuit.

I think my future project would be easier and faster. I need some new product for example this 1/2 DIN indash screen in order to integrate it in the next 2 DIN project but I haven't any way to buy it. It is only sold in RUSSIA!!

Is it possible that you could help me then figuring out how to calculate the 4bit checksum for a 16bit binary code? I have the 16bits and the 4bits for some cases but I would like to figure out the formula how the checksum is calculated.

coucouillu, i do wanna thank you, your project gave me an idea for something else in my car....

What's your idea?

oh i was looking at how you integrated everything into the panel, and i read another thread (that i posted on) about someone wanting to integrate a cb or scanner into their front end, to which i told them they could always just make a remote plate for the cb and scanner themselves using an empty slot somewhere. got me to thinking about the equipment i got around here that i use in my cars.......and hell i think i will be doing that to my gear lol. i've got a low grade exotic project going on and i'll be damned if i want my cb and scanner breaking up the interior (the antennae will be bad enough, thankfully the ones i have dont look bad lol. i also dont go anywhere without the two in my car) so i do believe i will be making such a panel. on mine however it will be a latched panel, it will flip down as it will be covering the dvd drive for my carputer.

absolutely outstanding, worthy of a blog

Hi all,

My project run its way but I have some problems.


I have got a problem with Commell LS-372 and USDC20D shut down controller.

The USDC20D shutdown controller use "short to ground" when sending signal to the motherboard power button.

But my Commell LS-372 Motherboard seems to need +5V signal on power button to power up.

I made all tests.

When the motherboard is powered but off, first pin of the power button header is nothing (not grounded, tested with multimeter) and the second is +5V.

If I short to ground the first pin, the second or both, nothing happen. But if I supply +5V to first pin, the motherboard wake up.

My shut down controller do not short pin together, it shorts pins to ground.

But ground , this is not +5V so the motherboard do not wake up.

Can someone help me with a little schema?

When the input in grounded, the output is +5V (or the 2 outputs are connecting together).

Thank you for help.

Have you figured it out yet?
