I attempted to update my nav software on my avic z140bh. I followed the instructions to a tee up to the point where i had to select "System uCom Write" i inadvertently pressed System uCom all Write. When i attempted to stop this it continued to write. Eventually i got an error message. I tried to remove sd but was unable to open screen. I removed battery cable and then reconnected but to no avail. Then the unit went black. I have not been able to revive it. I just checked fuse at rear of unit; it is o.k. Any and all suggestions welcome re: unbricking or removal of sd card. Thanks
