I just had my AVIC Z1 installed in my Dodge Charger Daytona. My Charger had factory Uconnect (which I hated to lose it worked FLALSELY!!!) much better than this pioneer.

Anyways if you have a Uconnect system and a phone registered to it be sure to delete the phone before you have an after market HU put in.

I deleted the connection from my cell phone after I had the AVIC Z1 installed and now my phone always comes up with a message stating the Uconnect wants to establish a connection. Very annoying!

Not sure what I'm going to do yet.

UPDATE:

I located the BT module and disconnected it. It was interfering in several ways once the pioneer BT was added.
