Hi i just got done with upgrading my z1 to z3 with a new hd 60gig. i have noticed that the gps is frozen and the arrow won't move. After a while may be 10 min or more the arrow starts to move but it will not display on what street or highway or ave iam on. Then 5 to 10 min later it will display the street , highway , or ave iam on. also i need to know if i could set the 5.1 channel for dvd since this button is grayed out is it suppose to be like this? and will the movies automatically play in 5.1. also i have noticed that on the 3d calibration the speed is always 0 the other like distance and learning work fine.

can i use the pioneer software to help with the heat lock up problem even if i just upgraded my z1 to z3 software would it affect the z3 upgrade?

You need to reset your 3d calibration settings, and your GPS should start to work again.

If VSS is reading 0, then it is not hooked up correctly or has come loose.

5.1 is greyed out because you do not have the 5.1 processor installed. This is an extra device.

Your unit will not accecpt the freeze firmware as it is already installed with the Z3 image.
