    Google maps based apps make unreliable .gpx files. Stick to .tcx files or make the .gpx files in Mapsource.
    I like bikes...

    They've always worked fine for me and I've been using them for years. I usually use .gpx tracks.

    Maybe you actually mean .gpx routes as opposed to .gpx files?
    More problems but still living....

    There are trackpoint and waypoint limits on your GPS. Not sure what the waypoint limit is, but for .gpx tracks the maximum for a single track is 500 points on my Garmin Etrex. You can reduce the number of trackpoints using bikehike (using the options), but for long rides its better to split the track in two (you can import many tracks into your GPS, but each track can have no more than 500 trackpoints).

    I find that 500 trackpoints is ok for up to about 100km - for longer rides I'll split the track.
