451 Smart Fortwo is incapable of doing a BMS software update by GPS.BUT they are not equipped to see if auto/update via GPS was ever done so the website offers to d/l it onto your usb and then you plug into car to try to install that firmware.
The dealer can do a firmware check in their shop, but a 75 mile trip there for me is an exercise in pain. So I'll trust that the gps update went thru at some point in time.
Such updates require a hardwire connection to proprietary Daimler link.
USB download was NEVER an option.
