Factory OEM SiriusXM nearly working in Tesla 2022 Model 3

they opened a SC in Temecula? I missed that...thanks!

Sure, NP. Its a bit off topic for this discussion but in any case, here is the info for it:

Obviously this is a choice you have to make on buying it directly from Tesla and being out those funds, but would Tesla allow you to return it just in case it doesn't work out?

 

[PhilCaps]

this is why I'm hesitant to do this unless we can get the tuner directly from Tesla. it's the only way to guarantee we get a working one.

now that I know there's one somewhat nearby me, I might give them a shot...

let us know the price and how to go about getting one from dealership

it may be a while. I still don't have my car back from the body shop. slightly annoyed about that, but that's off topic...

if it doesn't work out I'm sure it can be sold on ebay...there don't seem to be many available. someone far enough from a SC who has the ability to change it out themselves might want it.

it doesn't look like you need a VIN to order the C tuner

I emailed the Temecula SC order support, we'll see if I hear anything back. if not, I'll stop in there once I finally get my car back.

I also just emailed the Plano, TX SC to see what they tell me.

I might have found the problem with the 2022s. Someone check my work and verify:

So on the 2022 Models I was looking at the x908M/F connector and noticed the chassis CAN was using pins 13/14 which are shared with the tuner:

This is done through a bus/splice further up the harness:

On the Model Y, the chassis CAN enters through dedicated pins:

And similar to the Model 3:

I don't understand how the CAN protocol works: if it's filtering out the XM packets or if the network address is hard coded and changed in the 2022 for the MCU? Either way, I think the 2022 model might be having problems due to this change of several chassis modules entering through pins 13 + 14 for the CAN.

As I've said before, I don't have an adequate literacy of these diagrams but I can at least recognize patterns, seeing the difference in the 2022 diagram.

I got denied for inquire

If I'm understanding what you're saying, is the suggestion that the signal from the MCU for "Tuner Source Change" might actually be sent properly, but that its just never making it to the Tuner because of the different chassis modules?

Wouldn't that mean that simply splicing the CANbus from closer to the tuner (before the other modules) and running that directly to the tuner might allow for passage of the signal we're looking for?

 

[PhilCaps]

can you change channels via the scroll wheel?

Not only does that work but so does voice command

 

[ElectricNerd]

Not only does that work but so does voice command

So yours is working?

 

[ph0ton]

So yours is working?

Only on the older Model Y.

 

[ph0ton]

Isn't that just playing a streaming station, not the actual XM signal? Side note, are you getting the streaming SiriusXM channels now or are those coincidental? On my car it recognizes the command but doesn't respond to it (command not available).

Possibly. I haven't seen anyone really address the the architectural changes to the CAN in the newer models, and until now, I don't think anyone has seen it as significant. Looking at the older documentation on Model S's, the ethernet signal is on some sort of "EtherCAN" network. I couldn't find any further explanation of this and the Model 3 ethernet API seems unique anyways; there appears to be a standardized service-based protocol layered on the 100Base-T communication.

I looked through various CAN databases on the Model 3 and nothing mentions the tuner, FM, or Sirius commands. I interpreted this as the CANbus being on a different network but if they were somehow combined, how would that even work? If it were simply a matter of addressing the tuner via CAN signals, then maybe the SiriusXM ID is colliding or being pushed out by the chassis IDs, so you would need to change the tuner ID at your own peril, or isolate it from the modules (jumpers or wirelessly). On the other hand, it looks like the tuner is being controlled by the ethernet protocol, so if we assume that, why does the CANbus only interfere with the SiriusXM signals and not the FM?

I have more questions than answers because I only learned about this in earnest yesterday; also I still might be wrong about the chassis CAN and read the diagrams incorrectly. No one else has verified it :O

It changes the XM station on MCU by voice command. 100% getting XM from antennae not WiFi streaming.

Heard back from a Tesla rep and got this msg

1143716-00-C : not available

1143711-00-C: not available

1622932-00-B = radio tuner AVAILABLE for $225 plus service

 

[PhilCaps]

So yours is working?

Not in my 2022 m3. The pic is from my 2021 MY

What does "service" mean here? Is that installation?
