yes you did, but images can be deceiving, I only need the XM adapter, i dont need everything else in the toyota kit. I was trying to save a buck, or 20 actually.

Do we need to worry about wiring to a factory amp if we don't have the HK audio system?

As in, if I install an aftermarket amp with the aftermarket headunit, and want to use the idatalink on an 18 or 19, do I have to bypass a factory amp to use an aftermarket one?

Don't believe so.

I think I'm going to go down to my car when I have a minute and take some pictures of the HU and the interface so people can see it working.

Been on this site for 18 (!) years, and posting photos is still a pain, lol.

Anyway, 2018 STI Limited, Kenwood DDX9905S with a Maestro RR, rest of the audio is stock. The '18 isn't "officially" supported, but the only thing not working is the TPMS, which I don't really care about. [EDIT] Pics in better light.

I have a 2018 WRX 6.2 No Nav and No HK...I followed the guide for the SU-2 harness and the backup camera doesn't work...it switches over when placed in reverse but I get no image....any ideas?

My car doesn't have the telematics plug like mentioned in the SU-2 guide it doesn't have the SOS either.

Well, I'll be getting a '19 WRX (have my eye on Premium trim), no audio upgrades (will do that myself). Hopefully by early next year, iDL will have firmware and wiring harnesses fit for it so I can just plug and play (and only have to splice output lines to the aftermarket amp and the other lines from the iDL SU harness to the aftermarket radio harness) and have everything without having to do things like going and finding CANBUS lines or anything. Part of why I'm interested in the Maestro system is getting full system functionality retained without having to go cutting and splicing into the factory wiring.

Also, for the '19s on up, phd12v, in retaining the USB ports through Maestro, is iDL looking into (via the iDL serial cable) working with aftermarket manufacturers to allow AA/CP to be used via the factory USB ports at 2.5A charging? That'd be really nice IF possible instead of having to go through the aftermarket HU's rear USB dongles. Helps keep the factory interface look and functionality.

couple things are in play. Yes we are looking at making some sort of adaptor for the dual USB.... still in the works. And doing the 19 even with a harness and a new update, you MAY need to tap a couple lines. Granted it wont be terrible but may be a possibility. I wont know till we get an idea on HOW we are going to do it.It might be another adpator we will have to add to the SU2 harness, i just dont have a clear cut answer yet on it

I hope your product development guys are aware that we'd like to at least be able to use the system without much "app hacking" (or whatever the term for semi-DIY is nowadays) for a MY by the start of the calendar year the MY matches. Because the aftermarket HU manufacturers are pretty on the ball with it.

I know things don't move at the speed of "I want" in tech. I'm in avionics. We move at the speed of "this is to deliver in 5 years or more", so I understand. Still. Me want

I mean, to be fair, the only reason there needs to be any extra wire splicing with the '18+ is because Subaru made changes to the OBDII port. I don't know what, but it broke the functionality with the RR, and I doubt it's an easy solution.

Totally get where you're coming from though, it's a drag to have to wait. Still, the only way to make them go faster is to prove there's a demand.

[phd12v]

most of the 18+ vehicles across multiple makes (not all but a damn lot of them) have added basically a gateway in the can network. Meaning being able to get info and send info from the OBD2 connector is somewhat limited now. Say more for basic emission testing and basic troubleshooting. we need to be basically on the OTHER side of the gateway to be able to do the things we need to be doing. Also explains the multiple cans required to get specific info as well.

Indeed, but when your spouse holds the purse strings and says "We can't afford right now to replace your sports car that I wrecked." There's not much else one can do other than drool at the pretty new cars, talk about them on forums, and grumble "yes, dear"

It's interesting that things like the Accessport can still get through, albeit more slowly.

Lol, indeed.

Apparently she wouldn't have been as sympathetic if I'd just had a shop do all my mod installs. But b/c I did the work myself for the entire engine-back exhaust (except for the catback b/c of difficulty hauling around a CBE that was NIB in a BRZ, so I had the shop I bought it from do the install right then and there instead of taking it down to the rent-a-lift place and do it myself a few days later), and all my shifter mods (including spending time swearing and using a REM to remove the stock left shifter spring in order to put in Mtech shifter springs, and more swearing trying to get the rear shifter bushing installed from KB), she therefore "felt bad" and said I could get another sports car... just not another 2dr.

Else I'd have been in a BRZ tS lickety-split.

Words can't describe how much I loved driving a Toybaru twin.

I might have missed this described in an earlier post, but a question about 2018s with Maestro RR. Using the 2017 firmware for the 2018s with HK. Is it possible to jump wires to make the backup camera work (it's just a black image right now)? Also, is it possible for the SOS (Starlink) light to be green? I am not concerned with the OBD functions. I am using a pioneer w4400nex. Everything else seems to work fine just concerned about the backup camera for now.

Yes it's possible. phd12v has instructions elsewhere in this subforum about how to do that (I have forgotten what thread it's in).

[ems111]

I have a 2018 WRx premium with the 7” HU without go. I have a pioneer 2440nex wired to the SU2 and rr. Radio works and audio works but the backup camera switches over but is black and I have a check engine light, information alert, and my cruise control is flashing and steering wheel buttons don’t work. If anyone can lead me in the right direction on how to fix this that’d be much appreciated. I’ve read throw all the forms but none matching my specific radio.

[phd12v]

where did you get the can lines at?

What code is being thrown?

Update: rechecked every wire and I forgot to plug in the OBDII Red connector. Everything works now but the backup camera when switched over goes black and the gauges don’t work. I tried looking at the other post but I’m still not understanding what to switch to make it work.
