I am still on the free satellite radio trial and that skips when it first starts. It doesn't matter if you switch from a different mode or when turning the car on. After about 5-10 seconds, it repeats the first 5-10 seconds and then acts normally.
BTW, for the nay sayers who think i didn't notice if I was under a bridge or hidden from satellites by buildings or weather conditions: I've tested this in the very open parking lot at Walt Disney World's Ticket and Transportation Center (Specifically, Zurg's lot in the villain's section, a.k.a Magic Kingdom's parking lot)
