Default 2018 WRX Radio replacement/idatalink Maestro Rr

Hey guys so I have a 2018 WRX Limited without the Nav/Harman-Kardon System. I have been looking around and reading some post on the factory HU/upgrading the factory HU. As many have pointed out the factory HU sound terrible. I plan on getting the Pioneer Avic-8200NEX radio. There is a member phd12V (not sure how to link/tag users if possible) that works for idatalink and from what I can tell he has gotten idatalink to start working on an idatalink Maestro Rr firmware for the 2018 WRX and a new firmware should be coming out soon.

I would like to retain the steering wheel controls, backup camera, and the Subaru Starlink (for now) and from what I can tell idatalink Maestro Rr would be the easiest way to do that. Also the idatalink Maestro Rr give you different gauges that you can set up.

My question is should I wait for the idatalink Maestro Rr firmware to come out to get my radio/idatalink Maestro Rr or should I go with something else?

Just looking at all my options.

well....... you can get everything you asked for already. The only thing that wont work on the 18's is the TPMS on screen. It is gonna require a new firmware and more advanced installation process. That i can tell you.

If you dont mind the TPMS not showing up on screen, then it will work.

NOW with that said, if you are really good with hooking up wires and you understand what is going on, you can breeze through it pretty easily. If you doing a simple radio swap, it will work and the only thing you will need to do different is where to wire the can signals from. Which is not done at the obd2 it is done at the starlink module which is behind the factory radio.

If your taking it to a shop to get it done, have the installer call into idata and ask for Jason. BEFORE he/she takes the car apart so i can explain the reason for the can swapping.

The software for the 2017 wrx should work just the same, I think.

I've been looking at it with an Alpine HU I'd like to get from Crutchfield.

The Maestro RR is absolutely what you should go with if you want those things. I'm less excited about the gauges than I am about getting individual tire pressure readings so I can better keep an eye on tire pressures instead of relying on the annoying TPMS light.

Also, I've downloaded the install guide, and for what I want to do (use existing car speaker wiring for speaker and amp install, so I'd just run new speaker wire from the amp to the existing factory speaker wire, which is fine as the speakers I want to get are below 75W RMS per channel ones), the iDatalink setup is easiest as well. Just splice the speaker wire from the amp to the harness that comes with the iDatalink instead of splicing those wires to the aftermarket harness, and I don't even have to touch the factory harness for anything. The Maestro handles it all, including vss, reverse gear sensing, and parking brake detection (though if you want that off, just splice the green line to ground unless the unit has you do a parking brake dance to get into video viewing mode).

So, yes, absolutely worth it. And you should buy it as an install kit from Crutchfield so that you get all the necessary accompanying parts (like the vehicle specific harness, antenna adapter, etc).

I also like that you can program the steering wheel controls AND that they're dual function (short press and long hold).

I'd ask if the 2017 WRX firmware for the Maestro is going to be fine for the 2018 and 2019. If not, it's worth the wait. If it is, have at it and just update when the revision comes out.

if you want TPMS you might want to wait, it isnt a simple reflash and will require a different wiring setup.

I'm going to have to wait anyway. We're going to have to save for quite a few months till we're ready to make the down payment on a 2019 WRX Premium.

Can you give any hints to the complexity? Is it just a matter of running a line somewhere?

probably just pinning two wires into the module and catching can at the BCM along with the telematics can. And reflashing

I do like car audio and I'm always learning when it comes to car audio. I do plan on doing the install myself. That being said if a new wire setup is require for TPMS and other functions then it might be better to wait. TPMS and gauges are not a big deal but would like to have them if possible (no piont in buying the Maestro Rr if the TPMS and gauges don't work). Either way I will have to wait as the radio and other install stuff I plan on buying is out of stock.

phd12v do you have any idea as to when the new wire setup/firmware will be available?

Also thank you phd12v for the help and for getting idatalink to work on our cars and make a wire harness/firmware.

You can just wire it up as normal right now and simply wait till the new firmware comes out and flash it then. That way you can get it all in and using it now, and simply get your TPMS when the new version comes out. Connections will all be the same.

Where are you looking at buying from? Crutchfield?

phd12v said something about different wire setup being used for the Maestro Rr to get the TPMS to work. So I don't want to have to buy another harness and rewire. That is why I am waiting, unless I miss understood something.

As far as the radio and where I am buying from, I plan on buying from sonicelectronix.com. I plan on getting the Pioneer AVIC-8200NEX which is not listed on Crutchfield's website. Sonic Electronix does list the Pioneer AVIC-8200NEX but it is currently out of stock.

As for the Maestro Rr I also plan on buying from Sonic Electronix only because it cheaper (Crutchfield $139 and Sonic Electronix $97.99) The only thing Sonic Electronix does not sell is the Maestro Rr SU2 Plug and play harness.

i just finished installing a Kenwood DDX6904s in the wifes Forester XT. phd12v is a godsend with help. I can tell you that the gauges work by tapping into the red and blue wires from the telematics unit. Also you have to bridge the front speaker wires.

till looking for an adapter got the OEM XM antenna to the aftermarket SIRIUS receiver. this one does not work

Nice, how do you like the Kenwood DDX6904s?

What do you mean by "you have to bridge the front speaker wires"? I plan on running new speaker wires from the amp to the speaker.

if you remove the telematics unit (they say you can tuck it back but i dont believe it) you need to bridge the wires in one of the plugs. B1-B2, B3 to B4 etc. there are details in phd12v's other thread about the 2018 wiring.

we love the DDX, I have the DNX694s in my WRX (same unit with NAV) and i love it.

Lol, I guess I should've taken a picture when I had the unit out tapping the OBDII lines today.

If you skip the telematics unit, the starlink sos and info features won't work. It uses the front speakers to interrupt the radio when it connects to the operator, so audio from the stereo goes through it before it goes to the speakers... See a lot of "my front speakers don't work" comments because of this.

Mine is jammed down behind where the HVAC is, super tight but it fits. I'm using a ddx9905s with the stock HK amp and the RR, everything works like a charm.

So what I would like to know is, I don't want to skip/bypass the telematics unit. I also don't want to use the car's speaker wire(18-24 gauge wire) either. I would like to run new speaker wires (16 gauge wire). Is there a way to connect the telematics unit with my radio/amp to keep it working?

if your not amplifying the rear speakers (i didnt in mine at all) then switch the starlink wiring OUTPUTS.. (see my connector ingo in my other thread) to the rear speakers and then do the INPUTS with the rear leads from the new radio. Regardless if your doing amps on the fronts or not.... that way the telematics sees the audio input and audio output wiring and will not stay lit of red in the overhead console. Worst case scenario is having to wire up a couple speakers and mounting inside the dash area to simulate the speakers being there so the starlink doesnt error out

if that confusing i can try and break it down even further if need be

I do plan on amplifying both front an rear speakers.

Just a thought here, on GM vehicles with OnStar Pac audio from what I can tell was able to retain Onstar with their RadioPro5 when upgrading to an aftermarket radio. Not sure how they did this though. All I'm saying is that there should be a way to retain Starlink. Maybe add extra wiring for Starlink or maybe add a small speaker to wire harness or maybe something else. Just a thought. What do you guys think?

We retain the onstar as well with an RR.... and we also have speakers available for it as well.

You would need to do two speakers as it needs to "see" the speaker on the output side for it to not throw an error. I did ask about a small flat style speaker with two leads in it to have just for starlink, but its gonna be a hard one to get through. It would have to make sense from a sales and marketing point.

Didn't even realize the Maestro Rr could retain OnStar (didn't even think about it). That being said it would be nice if idatalink could add a small speaker to the Subaru harness like they do with the GM harness to retain Starlink. I think from a sales and marketing point it would make sense, since the WRX is not the only car that comes with Starlink.

So, does the Maestro RR will work with the HK package? Iíve been looking around if how to replace the factory HU to an after market HU and retain all the factory features on my 2017 WRX Limited including the HK package...
