iGo Primo Alpine INE W925R only Map Update

Hello,
I have an Alpine INE-W925R. It is with the stock Firmware and Maps. The iGo Version is 9.6.21.397588 from May 20 2014 and the Map is Europe NQ 2012 Q3.

I have read many threads but I don't understand everything. What I want to do:

- Get an backup from the system
- Update the Maps to a new Version
- Add TMC Pro

I don`t want to change the iGo version because it works good. The files are in the Navigation System, what can I do when something went wrong? Must I crack the exe file? When yes, how?

Thanks a lot
