After this whole issue with Uniden, I'll never purchase another one of their products... It's not just the siren app, but more it's that promised features set that still hasn't been delivered almost 7 months later... I have lost any and all faith in Uniden products and their support. With more and more agencies going encrypted, I guess it really doesn't matter anyhow. Uniden, I sure Im not the only customer you've lost, and I'm sure I won't be the last; and I won't be going back to GRE, or Whistler, or whatever they will call themselves in a few years either... Just my two cents, but these new Uniden's are nothing more than paperweights anymore; the last great scanner was my tried and true BCD396XT; while still having some decoding issues, the interface was far superior in my opinion. These SD-card scanners are a joke!
