I would try an NGVA3 antenna with an 8ft cable that seems to only exist on eBay these days. The 25ft one from Amazon is far longer than necessary for a Model Y and the shorter cable should boost reception. And/or you can also try adding a ferrite core to reduce interference though I'm not sure...

I found out the hard way that I can't "jump start" my Model Y with jumper cables. In an ICE car, you can simply use another 12v source, e.g. another car, by attaching jumper cables to turn the starter motor. There's no equivalent functionality in my Model Y where I can attach another 12v source...

@ArtK, @JayPaul, we're already acquainted here. You should be glad you replaced/are replacing the 12v battery before it's too late. The number of errors I got when the 12v battery died was stupid. I took screenshots when they occurred and you can see them here: 12v question

Any 12v battery or 12v DC source will work. I used my 12v battery charger to open the frunk. Both Energizer and Duracell say the shelf life is 5 years for their A23 batteries.

Sorry, I'm not very active here. I took screenshots of all the error codes when I got them. I really don't understand why the 12v battery is so essential when the main battery can work as a backup. You can see in all of these pictures that my main battery was at 79%. It's stupid how much can go...

Some more thoughts: You're absolutely right that no car in my lifetime has ever warned me or my family about a failure before it fails -- they just simply fail. However, I think we've been able to jumpstart every single one to get to our next destination. I'm just frustrated that I wasn't able...

My 12v battery died yesterday (Sunday) WITHOUT WARNING on my 2020 MYLR. Short version: my car was stuck outside, with the driver window partially open, and the car would NOT drive. With the rain in CA yesterday, it was a total nightmare. You absolutely can get stranded if the 12v battery dies...

I woke up yesterday (Sunday) to a dead 12v battery in my 2020 MYLR. I drove it the night before and no 12v warning or anything. I even charged the car overnight to 80%. In the morning, my wife couldn't get into the car. The only door that would initially open was the rear passenger, which was...

Thanks everyone! I got a few more reception drops with the antenna in the "tight squeeze" spot. I didn't remove the antenna housing or anything yet, so I'm wondering if the opaque black coating on the glass partially blocks the SXM signal. I'm reasonably happy with the 3D mount for now. It works...

Guys, this is pretty amazing. If the reception is perfect in that spot, then we've fully solved SXM on the Intel Model Y.

Thanks for the tip! I just tried it like this and it fit pretty perfectly--as in, no wiggle room but no stretching/pulling anything either. I am worried that you said that the fit was very snug in your car. I'm wondering if even a slight temperature difference in the summer will cause some...

I think there are two sets of grid lines on the rear window. If I'm not mistaken, the top set of grid lines is actually the FM radio antenna, built into the glass. When you pull off the trim cover and look at what's connected to the top grid, it makes sense. The bottom set is the heating element...

@RedTib, I forgot to mention this. Ask if your library's 3D printer is calibrated. The tolerances are pretty tight on the print. I think I made it about 1% oversized for the NGVA3 antenna. That's good for a well-calibrated 3D printer. If it hasn't been calibrated for a while, you might want to...

PLA will get warped in the sun/heat and will probably fall down after a while. I've never used nGen but it's supposed to be close to PETG, with some good and bad tradeoffs. I'm guessing nGen will work for this mount.

Sorry, I'm new to this community and not very active. @RedTib, the STL file is attached. Since STL files are not allowed to be posted here, I had to zip it. To everyone, I'm releasing this under a CC BY-NC-SA license. Among other things, this means you are free to share and remix it for...

A bit of background before I answer your questions directly... my biggest problem was using an off-brand antenna at first. I played around a lot with locations using the off-brand antenna and realized after a few different iterations that it was never going to work. The SXM brand antenna worked...

I used Tesla part 1143711-00-B, so I can 100% confirm that it works. User crackers8199 listed two more known to work. There may be others.

I've finished the write up: SiriusXM on Model Y

I've gotten it working perfectly on an Intel Atom Model Y: SiriusXM on Model Y I'm wondering if someone here is willing to try on an AMD Ryzen Model Y and report back. I would look for a compatible radio on Ebay, with returns allowed. There are no permanent modifications to the radio, just...

If you want the STL file for the 3D model, let me know. I printed in PETG since this thing will be exposed to sunlight. My model fits the NGVA3 model SXM antenna and the 3M Command strips perfectly. I'm not sure if all SXM antenna models are the same size, just FYI. I know the off-brand antenna...

Sorry, I only answered half your question. The SXM brand antenna does not have a Fakra Curry connector. I don't think SXM makes them. I initially used an off-brand antenna that directly had a Fakra connector, but reception was bad. I can't recommend an off-brand antenna. Use the SXM brand...

I used a "SiriusXM NGVA3" antenna. The one listed on Amazon has a 23-foot cable, which is waaaaaay more than you need. I've seen ones with short cables, but same model number on Ebay, but in the end, you can't see the cable when it's tucked away and reception has been as perfect as SXM can be...

I've finished the write up, attached in PDF. As far as I know, only the Intel Atom Infotainment system works, but almost all the information out there is for Model 3. If anyone tries this on an AMD Ryzen Model Y, let us all know how it turns out!

Yes, SiriusXM shows up on the Infotainment system screen and I'm playing it similar to FM radio. My best guess is that they used the same Intel Atom hardware for Model S/X retrofits, so they wrote the SiriusXM software for Intel Atom with a flag to turn the feature on if the SiriusXM antenna is...

Yes, I did it over the weekend and it works. From what I've read, you must have an Intel Atom system and not one of the newer AMD Ryzen systems. You can either use a Model X or S radio that's the same dimensions as the Model Y radio. (See comparison picture below.) The Model Y radio has a...

I just replaced the radio on my 2020 Model Y with one from a Model X. It was far easier than I expected and looks far easier than the process on the Model 3 thread. SiriusXM works in the car now and I'm pretty happy with it. I took pictures during the process and can post if people are interested.
