Your Garmin help, please

So am I. If you actually need the heart rate/cadence stuff, like hippy, fair enough. But most people don't. And most people don't actually need the maps. They're nice to have, but the 200 will navigate you over a pre-planned course well and has a 'get me home' function, although it can't do on the hoof directions, you need something more expensive for that. But personally I never use that function.

The problem is eventually the battery will wear out, plus with the fancier units they may have a bigger battery, but there is also more going on inside the unit.

I watched a year old 200 (owned by someone who does plenty of miles) record 18 hours of riding with navigation on yesterday with no top ups and was impressed. Especially as it's about £80.

That's funny, I don't actually use the cadence or HR stuff. :)

I do use the maps a lot which I thought the 500 lacked and would be my reason not to get a 500.

Batteries can be replaced.

What does the 200 show you? Does it do turn by turn nav? I can see that being useful in some situations but when I'm exploring I like the 800's maps.
