[OSM-talk] Choice of GPS for bicycle use in London

[Barnett, Phillip]

That's annoying. I've just bought a Garmin Legend CX, partly to take
part in OSM, and it's a bit galling if that unit generates bogus data. 
Can anyone confirm this happens on Legend CX?

(It's also annoying that I can't get track logs directly out using my
Powerbook, but have to turn on my ancient PC in the basement. I was
hoping to do some logging in North Wales this summer, but editing will
be a pain - and may have to wait indefinitely. Anyone have an update on
Garmin's 'Mac support in 2006' statement?)

I've been using an eTrex Vista with handlebar mount here in Cork,
Ireland; mostly it works quite well, but is pretty useless on narrow
streets, especially given Garmin's stupid, stupid, stupid "oh. I've lost
signal. let's extrapolate track log points according to the course and
velocity at the moment I lost signal".

This might not sound like a big deal, but in the city I most often lose
signal when turning a corner into a narrow street, so the Garmin
extrapolates according to some course being followed mid-turn, resulting
in a nice plausible-looking straight line of completely bogus points.

The Garmin's NMEA output at least tells the truth, but still gives very
little useful data on narrow streets, so I've just picked up a Sirf Star
III-based Holux 213 for $35 on eBay. This should by all accounts work
happily in the depths of my backpack, where I can hook it up to some
small device like a PDA, subnote or perhaps a Linksys NSLU2. You
mentioned a Zaurus - you wouldn't have a good (cheap, reliable) source?

Cheers,
