Non-magnetic media should be totally unaffected by the rare-earth magnets. My guess is that the excessive magnetic field pulled a switch or battery contact out of physical alignment, making the reset necessary.
Some GPS units have a magnetic compass in them. These are the ones that can correctly show true north while staionary. The others only depend on the incoming satellite signals, so they should work, apart from mechanical problems.
I saw a company advertising humongous rare earth magnets who would not ship them without a signed liability waiver. They had horror stories about shattered hands and broken arms. So I guess a blood blister is relatively cheap, especially in the cause of science. Sympathies, anyway.
