 After the installation of the CCC Nav, do you have a sound from your speakers or can you use the rest of the functions ? Asking this because there is a chance that the nav unit you installed could be removed from the vehicle which had very similar VO and in that case it may work instantly.
 
Your dealer can do a VO change by doing Retrofitting of the NAV option via their equipment. Would you be in my area I would code your vehicle easily, but I am far. It is 10 minutes job to do if everything is installed properly.
 
You may use your navigation without a fan but only for the very short period of time, because technically it may overheat and get some internal components may get damaged. The best would be to make a simple fan cable and connect it before use of the nav.
