Installed mine with single CD in my 06 OB 2.5i and am thrilled with the audio results. Thank you jazzy.
Ran into an issue with the manual AC controls though upon reinstall. My temperature control (the famous light blue cable) has become uncalibrated and now I have to pull out the HU to try and adjust it back to normal.
Figures that it would become offset to the COLD side in the middle of winter! Set on full heat, my temp is significantly cooler than prior to the install.
I'll post if I figure out a good way to get it back to normal.
