2011 Mazda CX-9 with Bose system

I was attempting to install an Android head unit in my 2011 Mazda CX-9 and I got power but no sound so I was thinking it was a bad unit. I went to put back the original head unit and now I do not have any power to the radio. I have checked all the fuses and they are not blown. Also, the information center that is in the dash is not working as well. I get illumination to the radio when the lights are on. It is equipped with a factory bacup camera as well that is not working now. Am I missing a fuse that is not listed. I have done the battery disconnect for 15 minutes as well to try and do a hard reset to no avail. TIA for any help. Below is trhe link for the head unit
