kunix,
I need to fully restore a v.4.50 USA. Do you still have the original dump of my unit?
The flashed Language + V.2.60 has been tested during a trip of 2200 Km without problems, but when running the map without a route the navi freeze.
For me this is not a real problem but "obviously" someone doesn't want this "imperfection" ad want to roll back to the original.
