The module part numbers are different for both cars and pre vs. post LCI, wondering if this matters or not?
any help is appreciated
You can add a tuner to your car, although it's slightly more of a pain. You will need a MOST bus extension (route the Fiber to the SDARS unit), the Satellite module, and power/ground and antenna. You can use Power off of pin 17/18 going to the TCU and any of the grounds there.
In terms of software support, the CIC's have it but will require a slight amount of coding to tell the CIC that the tuner is external.
Since your car is prewired, you could run an antenna extension wire from the CIC to the donor SDARS unit in the trunk.
But in all honesty, it's better just getting your internal tuner activated.
