Does anyone know what the difference is between pre and post week 22 cars that allows Smartlink to be activated. Is it simply a new Bolero Mk2 or some major difference in the canbus that prevents an upgrade.   I found the Kenwood MIB upgrade on line and a box opening video. It is basically a couple of boxes, one an interface and the other the GPS brain, a gps antenna and various harnesses.   I am at a loss as to how the 'smartlink' change can be much different.
