At some points mine starts flickering and then it wont let me change from radio to media or vice versa. Already had the radio replaced once

There have been several owners that have had the same issue. GM is aware of the problem. So far a module replacement seems to be the answer. Your dealer should be able to get you squared away. Keep us posted!

Probably a bad supplier batch. Hopefully your second replacement will be an improved version.
