I heard there is a hack out there to add the vehicle dynamics to the Z110bt? Or split screen? These are the 2 main things holding me back and it would be nice if pioneer or somebody could do this.

Nope. Ask whoever told you the "rumor" how to do it and share with the rest of us

Yea until someone figures out how to access the file system of the unit it will not be hacked. Probably shouldn't hold your breath on this one either. The only unit to ever be hacked to a usable level was the F/X series and that was a fluke that we were able to get our hands on the files to access the system. If it happens though, it will likely be someone on here that does it.
