I need to replace the microphone on my Z110, but the CPM1083 seems really hard to get. I was wondering if I could use another Pioneer microphone instead...thanks

Can I use the CPM1064, which is the mic used with the Avic-910BT?

Actually, try picking up the $12 garmin mic from Best Buy. Multiple members here have said that they get better results using that mic than the Pioneer one.
