Do you remember the Nokia Internet Tablet (NIT) line? The 770, the
N800, the N810 and the N900 phone? I still have them and they are in
working condition (except the N810 which died few years ago). I have
bought the 770 as a new device but the others are second (third?) hand
devices.
Long time ago I also had the Nokia LW-3D Bluetooth GPS device. It
matches the 770's design and works on a Nokia phone battery. I lost my
one (already a second hand device) somewhere in the wild but I have got
another one recently. It is also a second hand stuff but looks to be in
good condition.
I was not sure it it will still work with current GPS network but it
does. It have needed an ages for the first boot (as it needed when it
was new) and it is not as precise as the modern devices are (it never
was too precise).
At first I tried to pair it with the 770. I was not successful. It is
possible that I forgot to do some magic steps (the 770 was the first
Maemo device and many features are added by the community it less or
more hacky way). It is a pity because I have the original Navicore
navigation here (do you remember that company? It did navigations for
many Nokia devices, among others). I still have the box with the CD
somewhere...
Then I have tried the newer N800 with its more advanced OS 2008. It
have worked from the first second. So I started the Maemo Mapper and
played with it. It seems that everything works as expected (I should
try if it still can download the OpenStreetMap tiles...). The Mapper is
just a map application, not a turn-by-turn navigation as the Navicore
was. It can load GPX files with POIs but not files with tracks,
unfortunately. Still, it is better than nothing.
When playing with the GPS I also checked other installed stuff. There
is the FBreader (a bit unstable as it always was), a music player (a
nice application but it does not like non-ASCII characters) and others.
The N800 still can work with non-https RSS feeds (there are still some,
you know). I can imagine I would be able to use this device as a travel
companion (for music, radio, maps, dictionary, to read e-books and so
on). But with that COVID still around I do not travel at all.
P.S. I must confess that I wrote this text on the Sharp Zaurus SL-C760
because it has a keyboard. Once I was able to write long texts with
stylus and the virtual keyboard on the N800 but these times are gone...
