Your Garmin help, please

No. To be safe you could stop the ride and start a new ride. Split it in 2 rides. Sometimes they will throw a fit if a ride is longer than a couple hundred miles.

You can then use an online tool, to combine the 2 rides into 1 seamless ride.

What's better about the mapping? Bigger screen would be good. But as with everything bigger = more power use, higher cost.

Almost everything about the 1000 is better than the 800, except the battery life. Not really an issue for me as I rarely, if ever, ride for more than about four or five hours. On the basis of the few short rides I've done with mine so far I would be lucky to get more than five hours from a full charge I would guess.

I have turned GLONASS off, but the 1000 still locks onto satellites almost instantly in Central London. I usually had to ride a kilometre or so North before my 800 would get a lock at all. The screen is better, the unit is more responsive to inputs and I like not having to plug it in to my laptop to sync rides (you can do it via Bluetooth or wifi).

It was expensive, especially since I had to buy two new k-edge out front mounts, but I got Evans to price match Wiggle and they threw in a £50 voucher which softened the blow somewhat.

Overall, I'm very pleased with it so far.

Don't see why it would. 2 or 25 Satellites, it makes no different to the chipset, which if I remember right, is qualcomm, which locks on to both GPS and GLONASS equally. I'd go as far as saying it will be less power hungry since it's finding satellites easier and thus not pushing power through signal to find more satellites.

It's different circuits though ain't it, so it's effectively running two GPS circuits (maybe). I still say it's the screen that chews the juice.

For the amount of DPI and brightness the screens outputs, it has to be. Might try a full power/ no GPS power down test between the 810/1000 at work and see how they fare.

There's also very little info about Garmin internals it seems. Would be interesting to see what chipsets are used.

I reckon you may be right.

The eTrex 20* use both GPS and GLONASS, it last a lots longer because of the battery (2x AA), I managed nearly 2 days out of it before the battery fully depleted and that include leaving it on at low brightness all night, if I use rechargeable battery on the eTrex, it might last as long as says the 810.

*screen resolution is very similar to 810 apart from the lack of touchscreen.

Consensus on the Garmin forums seems to be that it's the screen that consumes the most power. You can turn the backlight off completely which, apparently, makes quite a big difference to battery life. Also, the map screen consumes more power than the data screens.

Get the screwdrivers out!

Of course it's the screen, hippy is always right.

"I've made some measurements with my device: When running on batteries (3.0V) the eTrex consumes 70-80 mA without backlight and 100-140 mA with backlight. So a pair of batteries with true 2500 mAh should theoretically ensure about 30 hours of runtime. When running on USB (5.0V) the consumption drops to a little more than 40mA (no backlight). In both cases the consumtion rises 5-10% whith active compass. The energy required by the compass is dependent on the movement of the device: When there's no change in direction to be detected there's no consumption to recgnise. I wasn't able to recognise any influence on the consumption by the tracking-rate or during a routing-calculation. --Fröstel 14:11, 31 December 2008 (UTC)"

Can I use OSM maps on my etrex vista hcx? Know where I can get detailed ones that are more suited to walking rather than roads cycling? Or do you get everything when you download OSM stuff?

Some of these, perhaps..

The OSM cycle layer has the highest resolution and classification of trails/path, but I don't know where to find it to run on your engine - my app (mytrails) does it by itself.

You get everything you need on the OSM ones, I usually get them direct from source.

choose generic routable or if you like the colour green choose generic routable new style.
Then use the drop down lists to select the area or if you wish use manual tile selection.
I have used them on my etrex legend HCX and now on my etrex 30.

Also, the map screen consumes more power than the data screens.

That's good to know, I can just leave it on data and let the navigation pop up when there's a turn.

Been doing that with the compass, explain why I get a fairly consistent battery life with the Edge Touring, should change it to data screen (which is a little more distraction having all the numbers in front of you).

The Garmin 510 use both GPS/GLONASS too, very odd considering the 810 only have GPS.

I grabbed some from a German site. Took a couple of reboots but they seem to show up now. Ta

It seems Safari cannot handle Connect's 'Courses' in all their swagger. So I'm back to installing Garmin software of various kinds twice-a-fucking-day.

Fuck you Google with your malware dressed up as a browser and fuck you Garmin software dev's, nothing you create actually works!

#rant

Connect seems to be in full on failure mode.

Tried to upload a total of six activities across two devices, got two of four on one device and neither off the other.

Incredible.

I have to remove and re-add my 310xt from garmin express every time I want to sync. It sometimes works without a hiccup, and then sometimes I turn the device on to find its decided to turn off 'Data Transfer'. Fucking Garmin...

But still there is no credible alternative. Garmin needs some competition to make them produce items that work, or at least work more.

How are you liking (or not liking) the Fenix2 @Dammit ? I'm looking at a couple 2nd hand for running (&Tri) and possibly everyday wear.

I'm still a bit annoyed at the accuracy of the GPS, but that's because I'm a dork I expect:

It's "close enough" I guess, and other than that I have zero complaints - indeed I wore it as an everyday watch for ages, and probably will again.

How did you have it set to squeeze that amount of hours from it?

External battery, no route calculations, 1s recording, record to SD, um loads of settings. No idea what causes the failure. The one time it did die I was using navigation to actually follow a route and had changed external battery once already. Probably a mapping bug.
