I purchase a new # 497 handset when the old who was 10 years broke. I like to follow ISS Space station and they require that you regularly download the latest file to the handset. and it went fine too but mine Guided Tours is now completely gone and serve no longer, the menu's handset but when I choose Nights best, so nothing happens, the stands and seeks for a long time and then freeze the handset and must be restarted ..
When I put the handset to the PC and retrieve data from hand-set to see what's under Tours, then i get strange looking symbols as tours name, and I can´t remove it.
I've tried twice to refresh the entire handset with the latest version of the software so now its version "5CE2" but it does not remove those strange Tour description and I still can not download the latest Tour to the handset.
Does anyone know how I get the handset to be reset?
