Default No RCA Jacks for amp install

There are NO RCA jacks on the OEM headunit like there were on previous model Scions. There are 2 open jacks for harnesses to plug in to that may indicate that future models with this head unit or other cars (TC or FR-S) may have a subwoofer option that a harness plugs into on the head unit though... I need to do some more research. Here are some pictures for reference. The piano black piece just pops off (gently... I started from the corner by the passenger airbag light) and there are 4 x 10mm bolts that secure the radio to the dash.

There are two plugs that attach to the piano black piece (hazard switch and passenger airbag switch) that need to be disconnected before removing the trim bezel completely

After the trim is out of the way you can removed the 4 x 10mm bolts that secure the radio to the dash and slide it out at an angle. There are multiple connectors to remove from the rear of the stereo, but as you can see there are no RCS jacks built into the head unit... this makes me sad. I really do not want to use line converters to make RCA jacks, I may look into the Bespoke NAV headunit, but before doing so I am going to read up more on the Toyota Auris, and Toyota Corolla Levin ZR then scavenge the rear interior of the vehicle, and under the seats to see if the car is pre-wired for any kind of subwoofer option we don't have yet here in the states.

i have not seen RCA outputs in scion radios since around 2013..... once they changed over to the head units with the large screen in the center they went away with it

its a shame i really like the look of those head units but am not about to hack the wiring to make my sub work in my '10 xb

Samesies... I am hoping that as the aftermarket for these cars picks up someone will create some sort of a plug / play harness creating a powered line out converter for the OEM harness. I could easily draw a schematic / and a how to with a PIN out, but I have no way to produce the actual design

Could you yank that stock stereo out and replace it with something like a Pioneer AVHX5700BHS or something similar?

I'm really not trying to lose the steering wheel controls (or pay out the ___ for a module), and I like the back up camera as well...

You can probably have that Pioneer with the steering wheel controls, back up camera, bypass for just 400 bucks. I just can't stay with a stock stereo, it's never good enough.

Tap the rear speakers and use this:
Amazon.com : PAC SNI-35 Variable LOC Line Out Converter : Power Converters : Car Electronics Amazon.com : PAC SNI-35 Variable LOC Line Out Converter : Power Converters : Car Electronics

It works very well, and have used it in the past 3 cars i have owned, without any need to hack anything apart, or jack up controls.. etc..
