Firmware 15.23:
The good:
Routing in Germany seems to work now on routes longer than ~30km air distance, calculation does no longer time out.
The odd:
Display shows erratic behavior (menus flickering / switching) during route calculation as if an invisible finger would perpetually select some options. Effect stops after route is calculated.
Clock switches to 12h format after the firmware is installed once and has to be switched back to 24h mode manually.
The bad:
WLAN Connectivity is no longer functional, there are sporadic connects / disconnects. Wi-Fi Sync always results in an error message "Sync failed" (Bluetooth however is not impacted). On the Wi-Fi access point, the device pops up with randomized names shortly and then disappears. (n.b.: no issues with a 1030 in the same WLAN).
Touch screen is sometimes not responsive, esp. the left arrow <--in the top left corner to go back up one menu level sometimes does nothing, may lock up the device because no user input is possible
CIQ Store no longer usable (graphic in lower half of the screen is blackened out).
