I am about to give up my Casio ruggedized flip phone (kicking and screaming) and it looks like I am going to be forced to get a smartphone. I have a 2010 FX-4 (No navigation, the basic system) and I must admit I really enjoy using the phone thru the Sync system. I will most likely get and IPhone 5 or perhaps some other Verizon Android as a replacement. My question to you is what additional features might I use thru Sync with the proper apps using a smartphone?
