yes u r right it has to be chipped
I would recommend techtronics.com
U have two options, due to the chip being SMD chip.Basicaly i would not fit yourself.Unless u r fantastic with soldering iron.
OR
get them to fit it, they will pick up your player & fit the chip and deliver back to u.
U will lose the warrenty on player,but u do get 1 yrs warrenty on the chip fitted.
Hope this helps
