Did you de-register your old 660 on myGarmin and register the new one? If not, then it's possible that the new maps have been unlocked to the unit ID of your old unit which you returned to Garmin. Best to phone Garmin support to sort this one out, I think.
OK then, try a hard reset by pressing down and holding the on button for at least 8 seconds. This will put the unit back to how it came from the factory. Maps etc will remain in situ but other personal entries such as favourites and home location etc will need to be reentered.
Following any firmware/maps updates it is always advisable to do a soft reset which is achieved by pressing and holding the bottom right hand corner of the screen whilst pressing the on switch as normal to turn on i.e. not for the minimum of 8 seconds this time. A warning will come up asking if you are sure which of course you should press the yes.
