:D I don't have any to check. Perhaps my coffee has gone bad. Or maybe the 950 mile drive that I started at 5PM on Friday and finished at 8AM on Saturday had an effect.
The GPS wasn't working. Now it is. Perhaps the mere laying of hands on the defective board healed it.
Or... there wasn't just a bad solder joint, it was completely missing. The GPS functioned for years with a lead simply touching the through hole. Luck counts...
