Received my CC3 today. Installed it right away. Didn't take long(about 15 minutes), because I was only replacing a similar unit. First thing I had to do was determine which CANBUS Box to select, because my steering wheel controls weren't working with the one they had selected. My vehicle brand wasn't in their list where the CANBUS setting instructions were located. Luckily, I knew which one to select from my last head unit. This is my third head unit I have had in this car, and it had the same issue as my last one: I can't remap the steering wheel buttons. I am stuck with the default ones. My very first head unit was a Wondefoo, and it allowed me to remap the buttons. I really like reassigning the mode/music button to be a play/pause button. It isn't too often I actually change my music source, but I play or pause quite often. I guess if it was really important, I could reinstall the olde Wondefoo unit, just to see which CANBUS settings it used.
Once I got the right CANBUS settings, I immediately installed Car Launcher Pro. Everyone has their preference, but I like it better than any of the vendor supplied launchers. I have it installed on all my cars' head units.
The head unit is very responsive. With the amount of RAM and ROM(6 and 128GB), I don't forsee that changing when I install more apps.
Data connection with my SIM installed in the head unit works great also. I didn't have to input any APN settings either. Everything just worked right away.
This unit appears to have a higher output than my previous head unit, and I am going to need to reset the gains on my amplifiers tomorrow.
Overall, I am happy with my purchase.
