I just recently bought a 2010 EVO X from a dealer and the person who owned it before me but in an aftermarket stereo and didn't bother mounting it or getting the correct trim. I'm looking to buy the Android 10.2 headunit but I need to know if the stock radio was a Rockford Fosgate or not before I buy one. If anyone knows, I would greatly appreciate it.

 

Do you have a RF sub in the trunk? If so, it's the Rockford. If not, it should be the base stereo.
