Simon Posted February 25, 2015 Report Share Posted February 25, 2015 AS long as you red the information on the firmware changes and check the tune and setting after the upgrade you should be fine. Worst case you can always roll back to the old version. Quote Link to comment Share on other sites More sharing options...
