I bought the radio in this condition, I have no knowledge of its prior history. I'm not sure what it it needs to function. Everything in the photos is what you receive. The unit has wear from use and storage. This is being listed "for parts or repair" due to being in a removed from car state without testing; there are no returns. Please see all photos for condition and feel free to ask any questions. ***Sales tax of 7.75% is added to all California transactions.***
