I'm a proud new owner of the Tilt...I too have been a TeleNav user for quite sometime. My inital thoughts of 5.2 were great...lots of great improvements. However, I have noticed a glitch on the 8925. Once installed, my Today screen constantly flashes...similar to hitting F5 on a PC...a consistent flashing or refreshing....I uninstalled Telenav, and the problem went away. Have you heard any other complaints of this with Telenav?
