My 05 Base Roadster came with an aftermarket radio. So installing another aftermarket radio was a snap, no additional parts needed.

It slipped my mine, but when I went looking through some boxes, I found a spare OEM radio I bought many years ago.
Are all the radios the same regardless of Base or Limited? I know there are NAV units and amps for the Limiteds.
All I have is the radio itself, no sleeve or mounting hardware. What else would I need to fit the OEM radio? JC
