Not sure if this is a problem with my updated disk or not but I had a problem while on my way to the Redwood's this past weekend.
About an hour into the trip while on I-5 the navigation displaying such things as arival time, miles, ect. all went away. The only thing on the screen was the original Blue line indicating where I should be going. IF I made a turn that put me "off course" it would not direct me back "on course" Just show the blue line of whre I should be going... (Even if that was now many miles away from where I am now. )
I notced that If I shut my truck off It would not resume navigation, But I would need to retreive it from the "recent trip log".
Several times It would say (I forget what it was exactly) but to navigate to the indicated route, However Im already on the freeway and the navigation is tracking my movement on I-5. With No other roads around me???
Im going to put my original disk in and try to duplicate the issues.
