Personally, I'd recommend a bluetooth GPS - no wires, and they don't drain the battery of the PPC like a CF GPS would. I think the two best BT GPS units are probably the
Fortuna Clip-On (which uses a removable, Nokia cell-phone battery), and the
RoyalTek BlueGPS (which has a built-in, non-removable battery). In a few tests I've read, these units have the best battery life, longest range, and the highest number of satellites detected.
I have a 4150. I love the size, and I don't need CF. If your friend doesn't have any CF accessories, they might as well start out with the 4150. If price is an issue (and they don't mind not having WiFi), the 2210 is cheaper.
Software: I think the king in Europe is
Tom Tom. I wouldn't get their GPS, though - it's not very good, range is bad, etc. But the software gets high marks.
Finally, I'd recommend that you check out
gpspassion.com. The owner of that site lives in France, there are great reviews and active forums, and links to sites that sell GPS hardware and software in Europe.
Note: The site I've linked to for the products above is Semsons. While they're located in the U.S., they
ship internationally, which may be beneficial with the current exchange rate, even with the higher shipping prices. I've used them myself several times and will again in the future. I have NO affiliation with them, by the way. :mrgreen:
