Are these codes normal and expected after CIC retrofit?

After putting a 2010 CIC in a 2008 e90 and coding, I'm getting the following error codes:

00C508 CIC: Connection head-unit to diversity - open circuit
00C5AE CIC: Connection head-unity to SDARS aerial foot - open circuit

I'm pretty sure they're expected, but figured I'd check in case I coded something wrong, as it was my first time

the antenna cables to radio and sirius with your previous headunit were routed to trunk, where the external modules for these functions located
with the CIC, the modules are inside of the headunit
so you need to extend antenna wires to front dashboard
