I Just got a v7.1 DVD to upgrade the NAV system. On the package there is a label that says "Please follow the instructions on pant bulletin general information 07-37-'07 CY DVD upgrade for navigation systems (see dealer Daily)." I found this thread http://priuschat.com/forums/showthread.php?t=12889 but is the link in the thread goes to something not related. Is there anything special that needs to be done before installing the new DVD??
