Just using the Syn3 Updater to go to Sync 3.4 is the simple and easy way to accomplish this. Just follow the instructions on filling out the app to determine where you are on the versions (3.0.20204) and NAV or not, and then just go to the latest version of Sync, which is 3.4.23088. Again select maps if NAV. Let the files download and be placed on the USB drive, this is all automatic. Then place the drive in the vehicle, running, and wait 28 minutes to finish. You will need to pair your phones, etc., after all this is done, but you should have CP as long as the hub is compatible.
