I waited for 2 months for my official, legit copy to arrive. It arrived on a Friday and I had to wait until Tuesday for the server in Japan to come up to build my password. I attempted the install and SD 1 went on without a problem. SD 2 got hung up at about the 3% updating point. Retry errors. I took car to local Pioneer dealor that installed my BT90. My unit was hosed and only option was to send it off to be reloaded. Local dealors are not allowed the CD to reflash the unit. I am now 1.5 weeks with an empty hole where my stereo used to be.
I gave up on the retrys after about 50
