Back to your GLIB as mentioned above you need a device that connects to the internet and updates in the same way that anti-virus and application software updates work ...
Here's something on the same tack (and just look at those prices)!
Myself, I've being carrying databases (sometimes big 'uns) around on memory sticks for, well I guess it's
years now.

Meanwhile,
here's another concept! I see them on eBay for £ 43 and elsewhere for anything up to £ 60!

And, just a quick word on GPS loggers. The
iBlue 747 A+ seems to be "the one" at the moment. But I think I shall need to wait a bit before I have a play (that is, once the price has dropped).
That's it ... I really must get some work done now!
