I tested this unit, and it pretty much works with no issues that I can see, other than the speakers being not the loudest, but I think it's supposed to be like that. I don't know how to use the record feature with a microphone, but that part should still work fine.

This unit is complete for the most part except I assume the microphone is missing. This unit has been put away in storage, so it is overly dusty in places I couldn't clean. There is also rust on the metal grate for the right speaker. Overall, both the head unit and speakers work perfectly fine, no real issues I've encountered during my use. 

Comes with a power cable. Will be shipped via USPS Ground Advantage. Any questions or concerns, please feel free to ask me.
