GPS tech (Garmin, Hammerhead, Wahoo, RWGPS, etc)

What you’re looking at looks like the raw data - it’s pretty noisy and full of jitter.

Strava and other online services will almost always clean up your track by applying some signal filtering and snapping to roads if that’s an option.

A speed sensor could improve position tracking, but I've never been clear whether Garmins actually do that.

They do have 'Lock On Road' option but I believe it only affects where your current position is shown, and not the actual track it stores.

So I got my first GPS, a Wahoo and I'm about to draw my first route on RWGPS.

RWGPS seems to route loads of dead ends branches along the way making a 200k routing 240k.

Is there a way to fix this. I can't figure out how to trim the route effectively.

Edit: Haha, seems they their example for the 'delete section' function does exactly this, but requires the paid version.

Not sure what you mean, but with the free RWGPS you can delete points, and depending on which background map you use ( normal map, cycleOpenmap, etc.) the route it automatically draws between two points will be different . you can switch between backgrounds while plotting the route.

Hmm! Hopefully I get it to work when I have some time to look into it :-) thanks

What’s the Garmin 830 like for postcode navigation?

It works - but it's a bit weird. When you start typing the first 3-4 characters in it immediately jumps to a list of options e.g. 'N10 London' and won't let you finish typing the rest. If you click on N10 it asks for the house number (fine, if you know what it is, otherwise you just have to guess!) and then the street name, or scroll through a massive list to find it - so if you don't actually know the street name you are a bit screwed.

You can force it to go back and let you type the extra characters in the postcode search (you have to do it several times to put the whole thing in) but then it tells you that the postcode is not recognised!

IIRC I read something about the default map not having the rights to use a 'full' postcode search (so only first 4 characters will be recognised - hence the weirdness). Maybe the OSM version works better (I haven't tried) given there seems to be no one complaining about this except me.

TL;DR .. it works fine providing you also know the street name (and preferably the house number)..

Have had similar frustrations with the edge 1000. My problem is that if you don’t know the house number it can be difficult to get the street name list to come up with the actual street I am looking for.

I don't think I've had that particular problem - I usually just type 1 if I don't know it to get to the street name, but maybe I've just got lucky... :)

Same thing with my old Edge Touring, post codes are a pain.

talking about old edge touring, i changed battery a few days ago after and its a success, back to a decent battery life. its probably been discussed many times, but its pretty easy.

I premiered my wahoo elemnt roam by using a route made in rwgps and turn by turn navigation. It works but the position was constantly lagging a couple hundred meters. Is this what its like? Or can this be amended somehow?

No, that's not normal. I'd get in touch with wahoo support if I was you.

Yeah I've done plenty of TBT routes with my roam (through strava though admittedly) and its always been spot on.

My Elemnt Bolt is always pretty much spot on. A couple of hundred metres is quite a disparity!

Thanks for letting me know. Ill update the firmware and try again before contacting wahoo.

How do I turn off the 'ghost arrow' on my Garmin 530?

Virtual Partner? I don't think the newer ones let you.

Rubbish!

Yep. I'm sure its been asked a couple of times before, almost certainly by me. It's fucking annoying and I don't need extra beeps reminding me how slow I am. Garmin wankers.

Turning off tones was literally the first thing I did when I unboxed it.

Tried searching but to no avail.

@hippy (or anyone else), what do the different lines mean?

It's saying to follow the left line, but then after a while it says I'm off course? Recalculation is edit: apparently not turned off.

The darker one is your route. The brighter one on the left is the Garmin's best guess at your route based on the maps that are active. If you know your route is good, generally stick to it.

Sometimes you might take a wrong turn and it will try to get you back onto your route, in which case it'll also be the brighter "Garmin pink" thing.

Thanks for that. I don't get why Garmin just doesn't send me on my route. In this case it's telling me to ride in the car lane instead of the separate bike lane next to it.

It's because you have TBT directions turned on. In that case Garmin has to recreate your route using its internal maps to work out where the turns are. So that it can direct you in the wrong direction...
