2007 to present (500, 500C, 500L variants). Blaupunkt CD, Continental units, Uconnect
Does a Fiat 500 with Uconnect need a code? Generally no. Uconnect touchscreen systems do not use the classic four-digit radio security code.
Where does Fiat put the code card? Most often in the handbook wallet or the service book. Some cars had it tucked in the glovebox.
How many attempts does a 500 radio allow? Fiat units are less forgiving than most — commonly three before a timed lockout, so verify the serial before you start.
