If you get SV info, that means that you are seeing some satellites so the antenna is probably not broken. If it hasn't finished by now, you probably need a better location for the antenna. The Progress should go up regularly. It may go up for a while and then stop for a while as the satellites go in/out of good-enough positions. The Self Survey is trying to figure out where your system is located. It averages over many (1000?) samples. It probably only uses "good" ones. You need 4 satellites to determine your location and the time. Sometimes, even if you can see 4, they are not located in a useful pattern. (For example if they are all in a line, you can't tell how far off to the side of that line you are.) After it knows where it is, it changes modes and solves for time only. That allows it to keep working with only 1 satellite. -- These are my opinions, not necessarily my employer's.
