I had to call them but still haven't gotten around to yanking the stock radio. There is a modification that you have to make to the harness and they will give you a custom file to flash the RR2 with.

I was going to rip the harness apart tomorrow to look at all the actual connections, and trace them out. I figured something on the harness is not wired correctly. Maybe I will wait until I can call them on Monday then. Thanks.

so after some time on the phone today with idatalink trying to trouble shoot my problem, they came to the conclusion that the rr2 unit was bad....Crutchfield is sending me a new one so hopefully I'll get back at it later this week...

Update: 8/7/20
Received new RR2 from Crutchfield today and proceeded to install, this time with the CAN lines military spliced with solder(they said t-tap was bad).....the same symptoms, radio will not automatically shut off when the car is shut off. Car info, gauges, TPMS etc do not work. When I look at the CAN STATUS page it shows an error: stufferr and count:9... I have lost faith in the idatalink tech support and believe they are lying about this unit and SU2 harness being compatible with the 2020 STI, literally everything is Plug n Play except the two CAN lines..

According to the below link the SU2 harness is now compatible with 2018-2020 cars...I don't believe it.

Idatalink states that the mestro rr/rr2 does work with 2020 STi's BUT only if you have the the non-amplified/harman kardon system.

Also I did read somewhere on there site that Idatalink is making a new wire harness SU3. The new SU3 (if they are making it) might work better when it comes out.

I would try and call them again and see what they say.
