I contacted Pioneer customer service 3 times regarding an update for the Z1 software. (nav and system) They have given me several different answers. One of the customer service reps said the Z1 has no update, I called back on another day...the rep told me to check back next month. I think they are having problems with the upgrade disk for this unit. They don't have any specifics on it, and won't give me a straight answer.

i think thats fairly common for all customer support people. If they dont have a script to your exact question, they are going to make something up.
