I’m not sure I have the guts to do this but also can’t afford to spend close to a grand for even a used unit. Was wondering what your experience was with removing the AC vents? Also, what’s it take to get to the hard drive in the actual PCM. I see you note it’s right on top but do I need to unscrew the top case. Have yet to open my dash up. I’m pretty nervous jacking anything up because then I have to look at any mistakes or scratches I make. It’s rebooting every 3 mins and making me mental! I can hear it’s the hard drive. I use to work on computers so feel relatively comfortable with cloning and replacing, just can’t wrap my head around the actual tear down.2) The drive is on top of the radio unit. On the Cayenne I was actually able to pull the HD without needing to disconnect any wires. 3) I got a Kingston 120gb from Amazon.
