hello
i have a 2007 x5 that i left in a garage for 4 months in florida,after returning i tried starting my car without charging the battary and the car car started right up,but after i started it up a diagram of a battery showed up where the odometer is but now the display wont light up and the screen is dark and the radio does not work.i am not sure what to do. i tried to disconnect the battery for about an hour or so but that didnt help, and i checked all the fuses and they all seem to be good.any help would be appreciate it.
.

thanks
