Yep- trying to retrofit the factory 360 camera system in a vehicle that didn't come with it from the factory would likely be really difficult too- not to mention expensive. If you could source the various exterior cameras and parts from a wrecked vehicle, it might be more manageable cost-wise... but buying the OEM parts from a dealer (even one online that sells at a discount) would be really expensive. The mirrors with the cameras are especially pricey- $1142 each (MSRP). The front camera runs $425. The dash button runs $109.
If this feature is something that you are willing to invest in- then maybe reach out to a few shops in your area that have the expertise and might be willing to take this on. Even if you buy all the parts- they'd have to figure out the wiring and also figure out how to tie it into the infotainment system's display. I don't think that it was ever designed to work with the XLE's smaller infotainment display (2020-2022), but I think that the Camry's 360 camera system works with it- and it might be the same screen size- maybe the same head unit.
Any way you look at it- it's likely going to be a very pricey experiment. Pricey to the point where you might want to consider how much it would cost to retrofit your XLE with the system- and compare it to how much it would cost you to trade in your 2022 XLE and maybe look for a slightly used 2022 Limited or Platinum that already has that feature built-in. Plus- you'd get all the extra bells-and-whistles of the Limited or Platinum grade if you did that.
For example, a 2022 XLE AWD with 20,000 miles has a trade-in value of $34,500. You could expect to pay roughly $39,800 for a 2022 Limited AWD with the panoramic camera option (also with 20,000 miles).
That's an upgrade cost of $5300.
Looking at just the two exterior mirrors, front camera, and dash switch- those alone would cost $2815... and odds are you'd pay another few hundred in labor to have it all installed. Add in the wiring and potential cost of trouble-shooting the system until it actually works properly in your car- and odds are you are up to $3500ish. That's a lot of moola- and makes the idea of trading in your car and upgrading to a Limited seem a bit more appealing- especially since you'd get real leather, ventilated seats, a heated steering wheel, JBL audio with navigation, upgraded headlights and high output fog lights, ambient lighting, 20" alloys (vs 18" on the XLE), parking sensors, a cargo cover, and front side acoustic glass. You'd also get the larger 12.3" infotainment screen. Best of all- you'd be upgrading to the better AWD system in the Limited (assuming that this isn't a hybrid model).
Plus- you wouldn't be voiding your warranty on all of the stuff that has to be torn apart on your 2022 XLE to get this camera system to work.
