2020 BRZ Maestro Flash Help.
 

Hello, been lurking since i got my 2020 BRZ in June, but this is my first post. Tried to find a solution but nothing came up. Crutchfield sold me a Pioneer DMH-W4660NEX, Maestro interface module and the recommended wiring harness'. When installing the maestro, there is no 2020 brz file and their forums say there isnt one yet. No response from them what to do about it though i assume they will tell me to return it. I tried using a 17 BRZ file that didnt work and im going to try the 19 brz file tonight or tomorrow. Does anyone here have any solutions for me?

I have a 2020 86. When I replaced the HU and added the RR, I flashed it with the 2019 86 firmware (the latest available for the 86) and have had no problems. Everything functions as it should. The BRZ? No experience in that realm.
