6 Disc fit in an 04 ZR5/Anyone Tried These Units?

[KnuckleheadS10]

While my crew is in the shop for the P0300 code at high RPMs, I was looking at modified stock audio, specifically this http://imgur.com/vCMCXi1 unit which an audio shop on Etsy sells - basically upcycled stock units with fresh buttons and auxillary/Bluetooth capabilities. My current stereo in my 04 is just the disc + tape, and I was wondering if there is any interchange where I could pop this 6 disc with BT in instead, and also if anyone has ever given something like this a shot?

Since you have an '04 you have a double din radio. I would verify that unit you posted is indeed a doubble din radio. If they could provide a picture of the rear connector on the radio that would also help immensely to determine whether or not it will be a direct swap.
