The eMap from c. '99 will dynamically adjust its sampling rate depending
on speed and the vectors it's seeing.

I have the eMap on my bike handlebars recording tracks and somehow
haven't run out of memory, and have spiders all over London now. I do a
few thousand km a year.

You could also just get a memory stick for the device. They're a rip-off
for the capacity but affordable nonetheless.

FWIW, the Maplin codes for the bike and dash mounts are NZ24 and NZ25.
That should get you in the right ballpark for the others if you go that
route.

I recently bought the TomTom 3 Navigator bluetooth GPS brick and
software, £140. Apart from some mismatch with the UI and what I
typically want to do with it it's really good. You can even get a pocket
PC for very cheap if you talk a lot (= 200+min/month tariff). They're
typically equipped with 128MB of memory and mine has a 512MB SD Card so
that's not an issue. The fact it's possible to program your device in a
sane framework (.NET) is a huge plus. Garmin, if anything, are
tightening up access to their internals/data.

HTH, Paul
