2018 STI Limited, crossing Ts and dotting Is

Post by joels » Thu Jul 19, 2018 7:21 pm

I understand there are a few "issues" with the 2018 cars, especially with the HK radio like mine has, but for the most part, it appears head unit replacement is plug and play outside of the need to tap 3 lines from the factory wiring. So, before I hack apart my dash, I wanted to just make sure I've got everything straight since the info is a bit spread out:

- TPMS doesn't function currently (FW update needed), but the rest of the OBD II functions work. These lines need to be tapped at the telematics unit, which appears to sit just below where the factory stereo is(?), blue and red wire...? Is there any chance the OBDII plug will work in the future, or should I just lop it off and tap the wires? Contemplating holding out on hooking up the OBDII stuff until everything is finalized.

- Backup camera works fine, but doesn't turn on unless the car is in reverse, FW update required.

- Everything else works and functions fine, but should I be using a FW map from the "2018" vehicle, or the 2017 specific to my car?

Is there anything else I should know? FWIW, new head unit is a Kenwood DDX9905S.

2018 had some changes from 2017 and that's the reason we don't list it on the website. the engineers are working on it however there is no ETA yet. I would hold tight, don't cut anything off, and we should have something out hopefully soon.

Thanks Bill. I'd like to hook everything up, with the understanding that it might not be fully functional, as long as the core radio functionality works... the factory unit is killin' me. But I can leave it in the box until everything is good to go if I must.

I have a 2018 WRX (not STI). Flashing 2017 firmware gets me everything besides the OBD 2 related stuff. Audio, steering controls, etc all work fine.

We are still working on a solution that is 100% functional like our solutions for previous model years.
