I'm selling 2 different audio in devices.

The first is the PIE adapter, which most people should already know about. It is in perfect working condition ($50):



The second is a China AUX in device. This device was advertised to support USB, SD cards, and 3.5mm headphone jacks. To be honest, the USB and SD card slot would only work about 50% of the time for me but you may have better luck. The music would sometimes pause so I dont want to advertise it with these features. The 3.5mm jack worked perfectly so I'll only list it as having that feature ($40):



Prices do NOT include shipping. Feel free to ask any questions.

 

is that a Raspberry Pi?

 

No, its the PIE adapter. This plugs into the back of your radio and give you an audio-in connection. The PIE adapter has the RCA type plug (I can include an adapter to change this to a 3.5mm headphone jack) so you can hookup an external sound source (such as an iPod, MP3 player, cellphone).
