Mine is a radio only unit. When I am ready I will look at it to see if anything looks remotely familiar. I ordered the stereo input jack from ebay 5 for .79 vs 1 for 2.99 at radioshack. I also wanted to add that if you are going to replace with an after market radio get one with an sd card reader rather than an aux port. With an AUX only your super expensive radio wont be doing the super expensive part (i.e. processing the music file) your android phone will be doing that. As where an sd card alone will be read and a signal processed via the head unit.
