(I had accidentaly posted this in hacks and am reposting here)

The official 3.0 has been pretty disappointing to me. I have two F90BT's and oddly enough, they each took the update differently. The most irritating thing is that the 90BT in my wife's car is now so buggy that the screen goes black. The radio stays on and if you touch the screen it comes back and works fine but it never did that before 3.0.

Has anybody tried to reinstall the Official 3.0? I don't want to completely screw up my system.

My truck's 3.0 hasn't done the black screen yet, but the bluetooth sucks now and the VR isn't as accurate. The lack of street labels is pretty weak too, but one problem at a time...

...anyone? I should get off early tomorrow and was going to try to first reinstall 3.0 (not sure if it will even recognize the SD cards once it has been installed). I'd hate to brick it. Any pointers?

I am having the same exact problem and am wondering the same thing. I don't want to break the unit in the process of reinstalling though. Any help will be appreciated!
