i use a newest software almost week, and just today it crashed and rebooted once. it it happened again i'll back to 0414.
i notice also two things. First, cold start always make weird sound change, for me the low and hi freq are boosted. You have to go to dsp eq and there move any bar, and all goes back to normal with sound. Weird.
Seccond thing. it is just a very small bug. If you set to display a outsite temp (taken from car via canbus), it appear near the home button in status bar, and the font is always white, in opposit to the rest of the status bar, which change font colour (white, gray, black) depending on a background of full screen app
And yes, all new what i notice in this version is the beep...beep sound when making a call. And if i have seted in a phone "play a tone when making a call" the HU also play this tone first.
