Waooh !!
Thank you for so much help. And so fast.
In fact I would like to be able to update my map (or install a new one that I could update). If I understand well first of all I have to modify or replace my navcore (wich is the original one updated).
Djc : I am going to use the Downunder files first. Thanks for your proposition.
Downunder : I am unable to install you DLL pack. The answer is :
"Firefox could not install the file located at
[Please Register or Login to download file] Unexpected installation issue. Console error 203."
Same same with IE.
(not the same code ...).
It is ok for the 9.20 Rider self.rar.
One first question : To update the navcore the procedure is the same as djc explained here
