I now have a USB port and can stream music from my phone using Bluetooth in my 1SS.
The physical install of the PDIM is easy but it requires a visit to a dealer so they can update the software in the radio using an MDI so the radio recognizes the PDIM.
Before ordering, I suggest you talk to your dealer's service department and confirm that they have the latest software for their MDI so that there are no issues during the radio software update.
Thanks to Iwantone2 who posted a PDF of the installation instructions: PDIMKit92213213.pdf
MDI is Multiple Diagnostic Interface, it's what the dealer uses to update the firmware/software in the Camaro. My dealer's service department had a hard time programming the radio to recognize the PDIM until they updated their MDI software to the latest version.
