Does anybody have a change log (list of updates) to the firmware for the NAV DVD's from 7.1 - 9.1? I'd like to know what firmware changes were made (not map changes)....for example is there better routing algorithms or anything?
I have a 2006 Prius with Factory Nav. I would like to upgrade the Maps and firmware if it needs it. I can get it done at the dealer, but someone here may know where I can get an updated Map and software at a discount.
The only user-noticeable difference in the system is the drop of the mandatory "I agree" screen -- it now times out, or you can press the map button on the wheel to dismiss it.
