That's a lot more work than I had hoped. Thanks very much for the info
though. If I'm going to be soldering I might as well try to fix the USB
port and GPS port at the same time.

I replaced the backup batteries in my GTA02s with supercaps several
years ago.

The parts I used didn't match the original footprint so it was a little
work. If you get the exact replacement part, it would be easy if you
have soldering experience.
I vaguely remember a software problem causing the line that charges the
backup bat/cap not being set high.
Good luck,
Ben

The secondhand GTA04 I have now is pretty beat up and can't charge
because the USB port is disconnected. I've been using a spare GTA02
as a charger, but every time I switch out batteries the clock resets
to 12/12/1999 16:00 and it's a pain to re-set it since network time
doesn't work. I couldn't find any information on the wiki about
replacing the CMOS battery to solve this problem; has anyone here
dealt with this same problem before and have recommendations?
I disassembled a GTA02 enough to see the battery, but it didn't yield
to gentle pressure trying to slide out of its bracket and I don't
want to destroy things too badly in my attempt to fix them so I
didn't push too hard. Because of this, I don't even know the exact
type of button cell to buy to replace it. Any help would be
appreciated.
Thanks,
