ASIN:B000SBRKDQ StreetPilot c550 Mobile GPS Receiver]]This order for the Power Adapter was to replace the one I orginally got with my C550. The part which holds the fuse came apart and I thought I lost a piece. Now I have 2, which is good because if I happen to be traveling I have a back-up in case one becomes broken. I really love my Garmin C550 and it has been helpful in finding places in my home town as well as other places I've been traveling. What a great invention!!!
