I have a new amp and subwoofer waiting in the living room for when the car shows up. Will post pics and an install write up when I'm done.

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.

Here is the model number / info from the stereo label:

I have emailed Pioneer about the head unit. There are no hook ups anywhere else in the car I could find that would indicate a future subwoofer option, BUT these are the two harness jacks that are open on the back of the stock head unit... Anyone recognize or know what these may be for?

That is too bad. Was hoping to see some preouts on this car. Do you think an aftermarket pioneer would keep all the features in tact like Bluetooth, steering wheel control, etc?

Thanks for the update.

I doubt it. That's why I've emailed Pioneer about the stock unit to see what these two unused plugs are for.

Any chance one of those has anything to do with the optional GPS?

I was under the impression that the headunit with the GPS was an entirely new stereo... Maybe, but I'm not sure at this point. I can say that normally on most car manufacturers cars there a NO empty receptacles for harnesses on the stereos and if anything plugs in to them the cars will be pre-wired from the factory for optional accessories... in this case there's not even any wires run to the headunit.

I'll definitely post up what I hear back from Pioneer.

Great mini-write up and pictures to go with it, this should be something that's linked to in some sticky thread since I know it will come up A LOT especially with the overall demographic of iM buyers.

I'm pretty sure the Nav radio is the same unit with an "update" put to the radio. Here is a LINK to Scion's page for the two radios.

I really like the Mazda3 as a replacement for the iM as I don't comfortably fit in the iM and I do in the M3, but I can't stand the look and replaceability of the stock radio. One of the only things holding me back on the M3. I hope you can figure this out, because since I have had my sub installed I wouldn't want anything without one.

Just curious... have you heard how good the OEM stereo sounds?

If Mazda wouldn't have changed the body style on the 3 I'd have looked at them a little harder, but dang the new ones are fuuuugggggly.

Agree to disagree. I don't mind the look, but I can't stand that radio.

Hey Nick The stock stereo looks link a single din when pulled out. Is there room for a full double din to go in there? I have my older pioneer avic f700bt i could thrown in there that has nav.

There looks to be PLENTY of room for a double DIN unit when opening up the dash... my concern would be that the OEM headunit the corners are kind of rounded... I'm not sure if aftermarket double DIN headunit faces would have fitment issues with the piano black bezel. Depth wise in the dash though is fine.

Glad to know that is the case since there are a lot of nice double dins on the market, usually that's what i've noticed the best of the headunits to be. Plus once installed they look more OEM than say a flip out.

Hey Nick - Has Pioneer gotten back to you about the two unused jacks? I want to hook up a sub too and would prefer to use a sub preout if it is available.

Thanks

Their response was "We do not support OEM radios all questions should be passed to the dealer." As for what the unused jacks do, they are for the Bespoke GPS and/or Bongiovi sound DPS that are sold as dealer options in the US and Canada. There are currently no plans for RCA jacks to be incorporated. I've already sold my subs and amp from my old car and decided to just get used to the factory stereo...

By the time an aftermarket deck of equal quality, rear view camera adapter, steering wheel controls, bluetooth / voice command, and GPS compatible gets all tallied up... I'd rather spend $1000 on lightweight wheels.

Im in the process of taking my old system out of my xb and transferring it to my im. I am waiting for my adapter harness to arrive so i can use the factory steering wheel control and backup camera. As soon as i get all the parts, i will take pics and post.

There was someone on another thread just asking about a steering wheel adapter... which one did you get and do you have the pin out already? What did you have to buy to re-use the backup camera?

+1 Pioneer wasn't able to help with this with a couple of head units I asked about. The closest thing I found was the tc/frs harness on pac audio
