Auto-folding mirrors and turn indicators part numbers

I use CarStream to play YouTube videos on the head unit. If you use AAAD to install it, you don't have to root your phone. Some have reported problems with CarStream and Android 14, but it works for me.

I recently tried to also install Screen2Auto so I could do full phone mirroring beyond just YouTube, but apparently that absolutely doesn't work with Android 14. You can only install one app per month through AAAD for free, so I plan to wait a few more weeks then try one of the other mirroring programs to see if they work with 14.

 

Got my last parts from Japan in the mail today. The seat bottom had to go to an upholstery shop for some minor mods that I wasn't comfortable doing myself. There are some plastic panels sewed onto the seat cover that hold the wiring connectors for the heated seats. They need to be transferred over to the new cover. I did the little ones for the seat backs, but those were a major pain for me to do, and there are a total of five on the seat bottom and a couple are much, much larger and would require a lot more sewing. For a person with only one and a half good hands, I'm very willing to farm that out to an upholstery shop.

But at the shop, we also discovered the Japanese model handles the child car seat anchors a little differently to the US model. The US model has little plastic panels that flip down to provide access to the child seat anchors. But the Japanese model just puts a fake seam in the same place that the anchor strap can slide through. Honestly, the Japanese version is a more elegant solution, but we're going to just swap that entire panel over from the US version. The upholsterer is going to remove the stitching holding that panel to the main seat cover, then stitch the new panel on in its place. It should be indistinguishable when done.


As for the rear headrests, I took a pic of the back seat with one of each installed. I plan to use the low profile headrests about 99% of the time for better rear window visibility. But if I ever end up expecting to have people in the back seats for more than 15min or so, I'll switch back to the larger headrests because they're likely safer in an accident.

 

I think I'm finally done. Like really, really done(after two full years of research, buying, and installing). I've completed the rear seat install after getting the bottom seat cover back from the upholstery shop yesterday. I'm not completely thrilled with their results, but I took it to another shop for a second opinion and he said the first guy did about as good of a job as was possible. If I just can't live with the results, he gave me an alternative suggestion that I could try down the road. It would require ordering another new seat cover from Toyota USA, so I'll wait until the Black Friday sale in November and see how I'm feeling then.

I took a photo showing the view out the back with the new Japanese(and European?) rear headrests to show how they improve the visibility over the stock USA headrests. The next time I wash and detail the car, I'll drive to a parking lot and take some video showing all the different upgrades.

You order them from Toyota Japan through an importer. lol

I believe the black cloth is 71940-47750-C3. Roughly $140 each at the moment plus probably around $70 shipping for the pair, so around $350 altogether. Tariffs could possibly change those prices.

According to my research:
71940-47710-C5 - black leather/red stitching(XSE/XSE+) (also what's pictured in the photo)
71940-47710-C6 - black leather/silver stitching(XLE/LTD)
71940-47750-C2 - black cloth/red stitching(SE)
71940-47750-C3 - black cloth/silver stitching(LE)

Light gray versions are not available in either cloth or leather.

Some of the part numbers might have been superseded, but these are good starting points.

 

I'm starting to think that adding Front Cross Traffic Alert and possibly Lane Change Assist to my car might turn out to be really easy. I thought it was going to take a different front bumper cover, new sensors, additional wiring, and maybe an additional module, but now it's looking like it will only take two sensors and two brackets. I haven't physically pulled panels to check, but all indications are that my harness has the needed wires and connectors. And all the bumper covers have the places for the sensor brackets to screw into.

The sensors are $565 to $805 each MSRP(depending on when the car was built) and the brackets are $75 each. Obviously adding FCTA and LCA isn't worth $1500 plus the cost of having them aligned, but I was almost considering it at around $750 after discounts. But then I did a quick check to see if the Japanese part numbers are the same and they are. The cost to order everything from Japan is around $350 including shipping. That actually makes it tempting.

Note that the ease of the installation will only be because I have a Limited with the Advanced Tech Package. As far as I can tell, it's the only Prius HEV(at least in the US) that has the needed wiring. All other HEVs would need to add wiring and connectors to make the corner sensors work, and that would be a nightmare to install.

Parts:
88215-47050 BRACKET, FRONT SIDE RADAR SENSOR, RH (x1)
88215-47060 BRACKET, FRONT SIDE RADAR SENSOR, LH (x1)
90159-60621 SCREW W/WASHER (x4)
90189-06238 GROMMET SCREW (x4)

Which sensors you'd need depends on when your car was built. I don't know if they're interchangeable or not. You need two.
882B1-48020 SENSOR, FRONT SIDE RADAR, MARK=T1 (3/2023 - 10/2023) - $640 US MSRP; $440 31% off; $350 +20% off; $125 Japan
882B1-48031 SENSOR, FRONT SIDE RADAR, MARK=TT (10/2023 - 4/2024) - not in US system right now; $115 Japan
882B1-48032 SENSOR, FRONT SIDE RADAR (4/2024 - 1/2025) - $565 US MSRP; $390 31% off; $315 +20% off; $175 Japan
882B1-30031 SENSOR, FRONT SIDE RADAR (1/2025 - current) - $805 US MSRP; $560 31% off; $450 +20% off; $175 Japan

 

I'm thinking at first either nothing will happen or I'll get an error. I'm pretty sure the new sensors will have to be calibrated by a pro before the system will work properly. I suspect the only question will be if the system will be able to recognize the sensor immediately or if it will first have to be initialized during the calibration.

But Japan just entered Golden Week, so there's no point in me ordering anything for a bit.



I also have to visually confirm I have the needed connectors in my engine wiring harness. I went to a dealership yesterday and had them run my VIN. The part number they gave me matches the one MicroCat Europe says is meant for cars with the FCTA option, but I don't think I'll believe it 100% until I see it.

 

Found one of the connector dead ends(I don't know what Toyota officially calls them), so it looks like my car really does come with the wiring needed for the front side radar sensors. It's going to be very hard to not pull the trigger on ordering the parts once Golden Week is over.

The only thing I need to decide is which version of the sensor I would get. The parts database says 47020 would've come with the car from the factory. Autoparts.toyota.com says 48020 for my model year. It also says 48032 is the newest version of the part(it supersedes 47020, 48020, 48030, and 48031).

I'm waffling because of price. 47020 and 48032 are both $175 from Japan, while 48020 is $125. $100 is a pretty big chunk of the total cost of the upgrade($350 vs. $450), so I'm really tempted to go with the cheaper version. Plus autoparts.toyota.com even says it's the right one.


What the wiring diagram says the connector should look like:



A pic of the capped connector. It's from the front passenger corner, a little behind the headlight. It's visible without removing any panels. The pin pattern(4x2) matches the pattern for the sensor connector.
