The only problem I see, when and if Pioneer offers an upgrade for current Z130BT owners to get Z140BH functionality, is the interface cable needed to have full Advanced App Mode capabilities. http://www.pioneerelectronics.com/PUSA/Car/Accessories/iPod-and-iPhone-Cables/CD-IU201S
Unless the Pioneer CD-IU51V is compatible with Advanced App Mode http://www.pioneerelectronics.com/PUSA/Portable/iPod-And-Bluetooth-Accessories/CD-IU51V
