Question on this unit for some of us that have aftermarket or want to get aftermarket stereos in the future. Will not connecting directly to the oem radio mess up the controls for the JB4?

I know we do connect to the CAN system to direct signals to the new head unit. I wonder if this will be ok. I plan on swapping and this will decide if I go JB4 or Cobb.
