Anyone else having trouble with signal dropouts while listening to the Sirius receiver? I get periodic moments of silence lasting about a half a second occurring about every 30 seconds or so, which I presume occur when the signal is lost and needs to be reaquired. Is this normal? Any ideas if it is fixable, or am I going to have to ask for a new receiver?

FWIW, I am operating in an urban environment (Seattle), but have had similar (but lesser) problems out in relatively open areas. Oh, and it's a new B7 with the Nav+.

I get dropouts, but only if I go under a bridge for a sustained period of time.

I lose signal in my garage, in tunnels, under bridges. Sometimes I get a random dropout but that's very seldom.
