Richard, thanks for your offer to help Roberto and take it from here. There have been many emails to LXNAV over the last month to diagnose and come up with a solution. Their warranty policy as you stated has been conveyed over several calls with Roberto. Last instruction over a week ago to Wings & Wheels from LXNAV was to have Roberto send the unit back for warranty repairs. Your solution could be a better option. Call me to discuss what has been covered so far
