I just purchased the new 9672 BlackBerry; When i attempt to use navigation on my new blackberry, the screen is filled with jiberish, (non-sensical symbols). Any advice would be appreciated.
Delete the Sprint Navigation application from applications list.. Powercycle the phone and download this link to the phone
