Hello all, my wife recently discovered my Zumo 660 that I thought had been left in a motel room years ago, and I have decided to put it back in service. I have acquired a replacement battery, and an updated memory card from Garmin with updated maps, but I have one problem... My battery door is missing. I've been unable to locate one as of this time. Is there anyone out there that has a parts unit or an old one that's out of service they'd be willing to part with ?
