Navi extras toolbox will not download. Indicated a corrupt file. Any ideas. I have disabled all firewalls and anti-virus programs.
Yes I ran into the same thing. I just did it last night. What I did was I used the file explorer to go into the download directory. I double-clicked the downloaded file there. When it comes up complaining at that point just tell it to run it anyway. Everything worked fine after that for me. I would mention the following things to keep an eye out for possible confusion:
1) After successfully installing the toolbox and running it. Make sure to allow it enough time to finish reading your usb stick after inserting into the PC.
2) Make sure you select for update the map updates that it should present to you as a found and available update. This will take time to finish.
3) You may need to change the name of one of the files as suggested in an earlier post to get it to move past the authentication.
My opinion is HD should have just sent CVO owners a USB stick for the first three free map updates. If they consider CVO owners some of their best customers (since they are giving them three free updates) this would have made them feel special, rather than what they likely feel after doing the update (which is pissed off).
Similar to the car companies who send out DVD updates after you pay for them. HD should just send out USB sticks. IMHO.
Good luck with your update.
