Hello Downunder,
Your comment on the following would be appreciated. I have attempted to download your 9485 Navcore for my Go720. The link on your page takes me to the download site and after a number of attempts I realized that the 'downunder' password was required. Confusion occurred because the site is in German with no option to change to English.
Seven options are then offered to obtain the download. I have tried 1,2 3, and 7 all of which appear to give me the same Navcore file.
After download I unzip the file which is successful but during the unzipping procedure I am warned that on every file, there are around 100, that there are CRC encryption failures with a query on each one of 'wrong password ?' despite using the 'downunder' password to unzip and as you instruct . I am using WinRar 3.7, could this be the reason for all the error warnings. The file appears to have downloaded intact so should I trust it to work OK ?.
