OpenStreetMap
Christmas is some months ahead; until then I have to find maps that are part of bylaws or related stuff. This allowed me to add some more features to the Heidelberg map, notably the Landfried area, just opposite the DANTE office (http://www.dante.de).

If you want a cheap GPS you can get a bluetooth one off ebay for about £15. It won't do anything useful on it's own, but if you install a program on your mobile phone, like GPSMid(free), then that can connect over bluetooth to receive the GPS data.
