I just received my 1st GPS and have a question for the experts. I have made a backup (as suggested here) and would like to set up my TT with a password protect code. When I connect to the computer via USB, and select "Operate my XL in TT home, I receive this message, "This function is not yet supported for your navigation device or operating system". According to the manual I should be able to do this. Any help would be much appreciated....
