Please report your observations here after installing and testing!

After some testing, I can say, that the following bugs have been fixed, which I also all reported to Garmin.

* 'Barometric Pressure' works now and can be enabled in by Setup -> Altimeter -> Plot Type
* Device does not freeze anymore, if Garmin Spanner Mode is enabled, a POI via 'Find -> POI -> Open POI' in detail view opened and you connect the USB cable, so the device asks, if you wan't to enable mass storage.
* Message 'Importing Shaping Points' is now correctly translated when using German language.
* Message "GPS signal lost" isn't anymore invisible, when no GPS signal is detected and being correctly shown.
* Voices, which don't support 'RealDirection', do now work and give turn-by-turn voice ouput.
