I'm sad to announce as someone with a 2012 Chevy Cruze LTZ with the touchscreen/bluetooth/xm/nav, that these instructions and the PDIM(22797218) do NOT
work. I did something stupid and ordered the part before reading to confirm it would work(since I had read nothing but success stories). But as it turns out the stock PDIM itself is deeper in the dash(I never even actually SAW the stock PDIM). But I COULD see where the harness and USB cables connect. I was able to get to those and disconnect them, and I was content with leaving the stock one in there so long as the new one could fit in. However, the USB connection in my car is full sized USB, not the 5pin mini-usb utilized by the new PDIM. Also, the harness connection pins were very different as well(I'm sure that's related to the SD card/Nav slot).
Thus far I've also been unable to locate another version of the PDIM that supports the nav. If anyone could possibly point me in the right direction I would really appreciate it.
I'm VERY disappointed.
