Turn Notification Distance

There's no way of changing it.

Alternative: change the scale of the map, you can see further ahead on the map and see what direction you have to go.

I have my scale on 120m, you can see about 400meter ahead.

A config notification is not available, but you can put the datafield "Distance to Next" on your training page.
The remaining distance to the next waypoint on the route. You must be navigating for this data to appear.

The only way I know to fudge it so you get notifications sooner is if you have 3rd party maps that support automobile routing (the garmin maps don't).

You can use that mode instead of say road cycling. As cars travel faster, the garmin changes the notification distance so you get them with about 1 km before the turn.

If you are following a preplanned course then automobile routing would work though if you are doing ad-hoc navigation be aware you might be routed onto roads you really wouldn't want to be on. 

If you have the map screen visible while navigating, it permanently displays the distance to the next turn (which counts down), so you can see how far to the turn long before the turn notification pops up.

The device would have to support "automobile routing". That is, it isn't a map feature.

It's available on my Edge 1030.

As for the maps If I try to navigate a course using this mode & the Garmin maps I get an error saying that mode is not supported or no routable routes available, however if I use 3rd Party OSM maps it works just fine

The Edges calculate the "turn guidance" at the start. That is, they create a list of turns during the "calculating" step. You can see that list by tapping on the text at the top of the map.

The Edge knows the location of the next turn and makes the announcement at 0.1 miles. A speed-dependent notification would change the 0.1 to something else based on the current speed.

I don't know why it increases the distance for the turn prompt it must be something in the f/w for the routing modes. All I know is that if I use Automobile Routing I get the turn prompts much earlier.

I used to use the Automobile Driving/Motorcycle Driving modes when garmin supported them on their maps to overcome some of the routing nuances of the Road Cycling mode & inherent avoidances that resulted in convoluted routes with silly distances being generated because of the garmin maps road categorisation layers, garmin insisted road cyclists couldn't ride on these roads They didn't understand that what cyclists can ride on in the UK is different from the US & the routing mode prevented routeing on perfectly legitimate roads, Now I use 3rd party maps, which have proper routiing for road cycling & have ditched the garmin maps altogether 

You do need the right maps for automobile routing but we weren't talking about routing in this thread.

It's possible later firmware for the 1030 added the automobile routing option (it might not have been in earlier versions of the firmware).

The default maps on the current units don't include highways (motorways) in the routing network, which makes them not really usable for driving.

The turn notification distance another thing and wouldn't depend on the map. That would be related to the routing mode (selecting "automobile" routing). That is, it would be a part of the firmware (which is what I said).

On older units, people usually used the Garmin "City Navigator" maps, which were maps for automobiles.

(I know about the issue with routing on UK roads.)

You can experiment using Course points in stead of TBT warnings. Course Points can be generated while designing your route with RideWithGPS (paid subscription), but I don't know the details and options.

There is another possibility by using the RTWTool of JaVaWa (https://www.javawa.nl/rtwtool_en.html). This program can - among many other very useful options - add Course Points to existing tracks or routes with warnings that are distance, speed and turn degrees dependent, settable in the 'Settings'. Save as Course File in .tcx format.

When using Course points turn Off the TBT guidance.

I realise the OP wasn't about Automobile routing. As the Edge doesn't support changing the notification distance I was offering up a way of doing it with the features that are available on the Edge

As far as I know Automobile & Motorcycle routing have been there from the beginning. It was later that a Garmin OSM map update stopped supporting it, when the map files changed (and got much bigger) to include more information like what is required for popularity routing

The default maps may not include highways per se, which I guess you know already but others may not but some roads in the UK seem to be classified as major highways or prohibited for cycling, which the road cycling routing profile avoidances deems unsuitable for cycling by default, with no option to allow them to be used. Hence ridiculously long routes being calculated for what should be a very short journey. Hence me no longer using the Garmin maps & using 3rd party maps instead, which do permit these roads

I didn't read that you were suggesting that the turn notification distance would be part of the firmware, my bad if it was in there I didn't & well, still don't see it. sorry.
