My 2597 worked very well for about a week.
In an attempt to update, Garmin express noticed the device was existing, but could not connect. Will not connect still.
I have tried multiple USB cables, on multiple USB ports.
Device actually connects 1/100 attempts... Starts firmware update process, and when device is unplugged, device will not reconnect again to complete firmware update process. and will allow no further progress.
No other forms of communication attempt can connect to device either, web updater, or web page with Garmin Communicator.
My last nuvi lasted 5 years and is still working... this one is tragic and sad. it barely works and takes an eternity to calculate routes, not to mention claims memory errors if you try to switch your car.
Please advise before i lose patience.
