Hi, i have an 500s and have had for a few months now. I usually run Civics etc so have no idea what im doing with Fiats!! ( even though i sell them for a living! ) I have ordered a set of coil overs and have wheels coming as well, but i want to upgrade the sound system, head unit etc. Can i do that without loosing the info on the TFT screen and blue & me etc? If so, where can i get the right stuff? Thanks
