I have the CD-SR1 left over from when I had my D3. I will be testing it with the unit when I get my module. As long as Pioneer didn't change the remotes codes with the with Z110BT is should work as it did with the previous Z series.
Hey were you able to confirm if the CD-SR1 is compatible? if so is all i need is the PAC WRI-P and CD-SR1 for my z110? and are all buttons fucntional.
