Hey Kestral, I went through the same ordeal as you last May with an "authorized" Pioneer service center here in suburban NYC. Actually my ordeal was worse! Called the center and the taped announcement told me they were open on Saturdays. I go there and a sign says they are closed Saturdays since the previous January. "Sorry for the inconvenience". Change your godd***d message then! I take time off from work to drop it off the following week. Early May remember. I explain to the counter peson what needs to be done and explain it is an upgrade per Pioneer- not a repair. Two weeks later tech calls me to tell me there is nothing wrong with it. Duh! I explain it again. Bottom line: I call every week for 8 weeks and get the same crap as you. Finally, get a call in mid July telling me that there is no such upgrade technical advisory on the Pioneer site. At this point, it just was not worth the grief. I pick it up. A week later I buy a 578.
