Depends upon what data you want to transfer, and the method will depend upon which version of Start you have. In a move so brilliant that only those with the magic decoder ring are able to fathom it, TomTom re-used the Start name on different models over quite a number of years. Any personal custom data you added to your XXL550 is likely to be transferable. If you still have the 550, it may be even easier. Let us know.
