If you can't see SM you probably wired the CAN wires to the wrong CAN. Post 06/2013 SM expects CAN2. You can tap into that on pin 9 and 11 on the headunit (yellow/brown and yellow/red wires). Then you'll see the SM.
Regarding missing lumbar and width, that's due to the red wire (0.75) in pin 1 under the seat not getting power. Give that 12v, and it'll work.
