No. What I was getting at was that maybe your car unit had automatically started a download when connected to your home Wi-Fi. Maybe try to see if there is an option to install without the USB drive in place by going to the settings option and checking the automatic update option to see if there are any status change or update pending.
Are you then suggesting this method to install the update, prior to inserting the usb with the update on it?
Also, does your unit have the navigation? I believe the update files for the non navigation unit are much larger than the update for units with navigation. Check to see if you have the correct version or not. Hope this helps
