First time writer to the forum. Question for the computer geeks. It is a long story but the inside my 2011 edge limited got very very wet. Cleaned up nicely however the NAV system will not come up on the big screen but is up in the left upper corner and beeps when I hit it. reads NO SD CARD. The card is in the slot. I tried a dealer card and it changed nothing. The USB ports still have power.
Aside from replacing the entire module any other ideas? I checked fuse 26 5 amp for gps and it is in tact.
