hey guys new here see if you can help.

have a 900bt with a gex-920xm reciever which has worked perfectly until now

i removed head unit to hook up my ipod cables and in the process damaged the

bus connector so i ordered a new cable hooked it all up and now the fuse keeps

blowing when i hook up gex ground wire. i have inspected all wires and they look

perfect i am at a loss could the gex unit have internal damage which keeps blowing

fuse? any input would be great thx eric
