Hi Angela,
I advise you dont do this yourself as you could damage your sat nav by attempting this, the pins for the usb connection inside your navman are very fragile and are likley to break off easily since the usb port has been moved from its original seating.
I can provide you with service for this by way of removng the unseated usb port connection and installing a new port so that it can be firmley seated in place as new. The part costs a mere 20 pence and i will do the repair for a fixed fee of £5, and offer you a same day as recieved return delivery to yourself.
If you would like this work done please send me an email to drewishuk@yahoo.com and i'll forward you my details for where you can send your sat nav to for repair.
Thanks
Andy
