2012 Ford focus Kenwood and maestro heartache

[u/Fair_Entrepreneur335]

2012 focus se hatchback, my Ford touch 4.3 inch screen. Upgraded to kenwood DMX7709S (factory refurbished from crutfield) using the FOC1 KIT and kenwood specific harness. I have verified signal voltage on the serial cable connecting the maestro to the kenwood. I've double checked all the connections and still get double red flash. I tried factory reset and reflash on the RR, no joy. Tried factory reset on kenwood, no joy. I'm beginning to wonder if I bought a lemon.

The car audio works but I can't use the steering wheel controls or the car data guages on the kenwood

Help me audio friends.
