The voice button on the cd-sr11 does not function on the Z1. At least not mine. I liked how the cd-sr11 had the "POS" button that let you change between the different map views and vehicle dynamics. You cannot do this with the cd-sr1. You have to use the voice feature to get this to happen.
i have the bluetooth adapter but still tha navigation part of the remote not
working that is the last thing that i got to make it work after that i took
the unit in and out about 5 times today but the z1 is very nice toy :D
just this problem with the remote
