Since upgrading to version 6.0, my 830 has started to freeze. 3 times in the last 2 weeks. Each time was at the top of a climb when there was a junction. Route guidance froze on the "turn" screen. The device was still working in the background but the screen was frozen and unresponsive until I pressed the power button for over 20 seconds to restart it. I think the Climbpro screen was on each time too, which I've just stopped popping up....will see if that fixes it.
