Hi everyone i have been reading that there is a upgrade for the z2 BT upgrade the thread said only for Z2. i was wondering if there is a BT upgrade for the Z1 and if some one can point me in the right dirrection thank you. i already upgraded my Z1 to the Z3 upgrade and have done the 2wire bypass.

Then you no longer have a Z1, you have a Z3 and have no need for the BT update that came with the Z2.

When i upgrade my z1 to a z3. Will i be able to stream music via BlueTooth? Also will i have to do the bypass again. it already works on the z1.

No, you won't be able to stream with the standard ND-BT1. No, you will not have to do the bypass again.

thanks alot guys you are the best keep up the good work that makes Avic411 the best
