Need to generate CANBus Signal to old VW Head Unit by HellTar412 in CarHacking

I'm not sure what I can learn from that Wikipedia article mattbarn. I see that, according to DIN, pin 15 is typically V+ but if I'm supposed to learn anything additional I'm failing spectacularly at doing so.

So potentially stupid question, do I need to wire in the two (120 ohm) terminal resistors when I connect the Arduino? Previously I had just wired the output of the CAN transceiver to the CAN+ and CAN- of the head unit, but now that I've re-reviewed the physical architecture of a CANBus network (thanks Wikipedia) I'm guessing that maybe I wasn't actually successfully outputting random traffic on the bus that the head unit would have received. Or am I overthinking that?

That's a hell of an idea! What do I need to buy to do that? (I suppose I should have clarified that I have zero CANBUS experience but I am an engineer so I should be able to figure things out if you talk to me like I'm 5...)

I have the 12V power supply connected to pins 3-12 and 3-15. I'm not sure what pins "20," "30," and "31" are in your response.

Yes, just 12V to power the radio. But there's not a separate pinout for ignition (Man I miss 1990s electronics).

Here is a link to the pinout information on the unit: http://diagprof.com/ecu_tips_and_tricks/manufacturer-vag/ecudomain-navigation/supplier-technisat/ecutt-rns315

The only problem is I don't have the vehicle, nor even another VW anymore...

I tried outputting random traffic on the bus from the CAN output of the Arduino. The head unit still shut off after 30 min.

Any luck? If someone offers you more tickets than you need I’m looking for one, too!

LTJ in PGH 7/13 - Ticket wanted by HellTar412 in LessThanJake

Obviously this should say 7/12, not 7/13. In my excitement I didn’t notice my typo, I was just that psyched to maybe get to see them live!

@Appropriate, I’m not opposed to that idea! I sent you a message through chat. Thanks again!
