Computer shows device is connected. Device shows it is connected to the computer. Garmin Express cannot find device.... this has happened on three other computers. I sure would like to use my lifetime updates so my live traffic function will work again. Getting frustrated!
I am sorry for the troubles. Please see the FAQ: Why is my Garmin mass storage or MTP device not communicating with Garmin Windows applications? If you continue to have trouble I suggest you contact us by phone.
