Need HELP in identifying items on a GPS unit's circuit board
I need to put items back onto this circuit board that came off. Just want to know what they are. In the picture below, they are shown with the arrow. One is a cylinder with "671 220 50z" written on it. The other is just a tiny rectangle with a solder connection on each end. My unit won't connect with satellites and I'm wondering if these that somehow came disconnected have something to do with it.
