I have a Z3 that I just had professionally installed (had a Z2 before). Problem is that I don't have near the reception that I had before. When I am out of the city, all I get is static. Places that I had reception before, now I no longer have anything. Additionally, every so often I hear what can only be described as an airplane flying overhead. It's the same sound every time, and obviously not an airplane. I was told there is a Z3 update that fixes that problem, but I think the guy didn't know what he was talking about. Anyone else experience anything of this sort?
