Tried the update for 3.0 for my non nav unit....followed all instructions to the T and still got same errors as before. First i got the error EM 003 but then i got another error i never had with the 2.3 update. It was error lst 005. This is some.bullcrap...my 1.0 to 2.2 update went up without a problem....the 2.3 never worked...called Ford....no help at all...You spend all this moneynin a car and then all this time to keep it up to date...Then NO ONE at ford when u call them know.anything or can give you any tips, or ideas..All they keep saying is...Must be something you are doing wrong......i am so freaking tired of hearing that...Look..I am not your run of the mill customer..I deal with electronics..I know it takes patience and you have to follow directions....But if sooo many people are having the same issue...then..MAYBE..CALL ME CRAZY..its not us..and as a world company, you should respond to your.customers....you should give us support....you should design things that work, and if they dont..then make ammends, fix it and take ownership...very frustrating...Alas..
