Does anyone know how to increase the volume on the navigation system in the 2010 Prius? Although I am still looking, I have yet to fing it in the manual I am a little hard of hearing (that's an understatement) and I have a little trouble hearing (another understatement), the voice John
Push "Setup" then "Voice" you will see the volume numbers OFF through 7 across the top of the screen. Page 242
Thank you, I kept missing it I am 5 days into my new Prius IV with Solar Roof and Navigation System I am slowly stumbling through all of the instructions John
I also have no problems with the NAV system. I use Garmim 780. Sorry folks, I tried hard to resist but I can't stop myself!
