1. It is no problem to some reading to gather needed infos before actually working on a device
2. We use terms that are specific for the TT world, sorry to say but one can't understand he has to learn it
3. We can only help if a user is willing to help us, this includes following instructions and providing necessary infos

You said you can't install the Navcore, from the stuff you write I would guess the messages is from the patcher - like FastActivate.
If the error is from Home I would suggest to try again after deleting everything from the TT except the ttgo.bif.
With very little effort the current 9.700 Truck Navcore and the current 910 Truck map can be found in the forum.
For the NC I even provide an installer and for the Truck map a version that can be used on 2GB devices.
The procedure is the same like on normal NC, so all the tutorials and instructions provided in the corresponding threads are true and correct.
What do you actually expect us to do? Use Teamviewer to download and install it for you?
Sorry, but try to help, it is up to you to accept it....
