It is good to hear from you! We have not had an inordinate amount of returns with the 9500i. Currently the USB port is only used internally. In the future you will be able to download and save your marked locations, and download other customer's saved locations. In the far future, you will also be able to download software from us using the USB port. We have no time line on when these functions will be available, but our engineers are currently working on them. Thank you for your patience, and we will announce any new capabilities on our website.
Thanks for your interest in Escort!
