Well, installed 184.108.40.206 and have to say (after ~2 hours of testing). Best Radio so far in my opinion.
Shows more signalstrength than any previous radio i had flashed, data-connections seem to be pretty stable and fast. GPS seems to be as good as always (monitored with iGo 8 R3, GPS-Infoscreen which shows the connected satelites, drove a short trip).
so far, it's looking good. has to show its quality over a longer time at more different locations, but currently it's looking really good...
