Expert Review of route

@richtea999
Thanks for looking at what I had.

This is just day 1 of the trip. Day 2 I stay and do some sightseeing , and day 3 I haven't posted yet. I wanted to use the advice on this segment.

I thought about the route you highlighted. But this goes through some of the hard hit areas from last years Hurricane. Thats why I avoided getting onto the BRP sooner.

I'm traveling solo and basically any fuel stations after 100 miles is getting a visit

This brings me back to the GARMIN ZUMO XT and how it reacts to these routes.

When you import the route and then start the route it "calculates" the route based on its own Garmin algorithms.

As I understand Via vs Shaping points. Garmin IGNORS Shaping points and ONLY cares about VIA points during its calculations when importing the route. That why so many VIA points.

I'm trying to stay on a fairly specific set of roads. If I reduce VIA points won't/can't Garmin then pick the roads that will most quickly get me to the next VIA point.?

Maybe I have it wrong

@Greenham

Shaping points (soft points) can be skipped without the Garmin sending you back to a skipped shaping point.
You must visit via points (hard points) or skip them manually.
Only start a route if you:
Have a connection with at least 3 satellites,
Are on the route or are close to the route.
Never start a route in the garage or at the kitchen table, because then the Zumo has to calculate to your starting point.
Again, use a maximum of 28 via points and place them at critical points or where you want to stop. For the rest, just use shaping points. I myself use a maximum of 7 via points in my route and form the route with sufficient shaping points.

@Hans-van-de-Ven-MR-MRA

Thank you,

I can reduce the hard points and use more soft points.

But

QUESTION .... Does the Zumo XT use the soft points when its calculating the route using the route I want to take.

[Hans van de Ven MR.MRA]

@Greenham
Yes

[Marinus van Deudekom]

@Greenham The XT has a nasty habbit of thinking it can make a better route then the one you planned. To force the XT to do what YOU want add extra shapingpoints. Use the compare function in the planning mode to see what TomTom and OSM do whit your route. It gives you a small inside of what might happen to your route if you didn't put in enough shapingpoints

[Guzt]

• only use shaping points (hands) where relevant (fuel stop, coffee stop, lunch stop etc...) and use different colours accordingly.
• once your route finished with the car activity profile using the HERE map set, optimise it by changing route calculation from fastest (standard) to shortest and adjust to original. Switch back to fastest and adjust again if necessary.
• if wanted, now you may switch to the TT map set and do the same.
• use the gpx 1.1 (route, track poi) for your XT.
• you can leave the recalculation mode on your Garmin device to automatic without any problem.

@Guzt
Just for clarity, Via points are hand shaped not shaping points.

[Marinus van Deudekom]

@Guzt If you use recalculate on on the XT you're in for trouble. sooner or later the thing will for shure mess up your carefully planned route. The XT has a will of its own. So my advise is leave it of.
when using the 1.2 export using the Drive app. The route, witch must have some viapoints in it, will be shown on your XT. I alway project the track witch comes automaticly with the 1.2 export under the route so if you deviate dfrom the route you can still come back to the route using your eyes. If you have recalculate on, that would bee the chance for the XT to mess up your route and believe me it will for shure.
have fun

#1 Shaping vs Via points. Got that. Only use VIA points where you actually want to stop.

#2 Heres where I get confused by your comment, I started with the motorcycle profile and the (Here) default. How do I optimize changing from fastest to shortest

I don't understand the back and forth of fastest and shortest

I have compared the route with TT in the past

#3 I just learned from you guys recently to use GPX 1.1

#4 I understand the Leave recalculation on the Zumo to automatic

[Guzt]

@Marinus-van-Deudekom Did I mentioned to use 1.2? Don't think so.

[Greenham]

@Greenham

This is great. I won't pretend to understand why you have to save as a track, then load it and compare with the Route, but I will do it.

In the Motorcycle profile it does allow me to route optimize. Or is it doing nothing.

I used Chat GPT to create an English version if you want it.

THANK YOU AGAIN

[Greenham]

@Guzt

You say in the doc when downloading to Garmin to do it in. 1.1 format

[Guzt]

@Greenham In the toolkit under optimize you have the possibility to change the route calculation. That option is only available in the HERE map set when you make your route using the car/auto mobile profile.
You can either add a copy of the route (hamburger menu - routes - add) or make the track underlying (which I prefer) visible as reference (I already have an uploaded track of the route as I make all my routes mostly in Basecamp).
When one recalculates with shorter distance e.g. the route will differ from the original. By dragging the recalculated route to the track or reference route, you force the route to follow the original as intended. Hence the reason that one can leave auto-calculation to on on the gps when using gpx 1.1

[Greenham]

@Guzt

Thank you again. I finally did it. I used your steps and saw 1 or 2 places that the track and the rote did not align. Fixed that, changed to shortest, no issues, exported to my Garmin in 1.1 Route.Track.POI

I've learned a much from you. Thank you

Here is the English version of your instructions

[Marinus van Deudekom]

@Guzt exactly that would be my advise
I see that you still use Basecamp from way back when. Keep up with up progressive planning of MRA and make the world a bit more beautifull

[Greenham]

@Guzt

1 last question.

What do you do when the tracklog and the route don't line up, but you want to KEEP the route. I can't move the Tracklog to match.

Will the Garmin follow my route or the tracklog?

This is the issue with GPS's and Motorcycles. If you want to take a more scenic route will the GPS let you?

Mike

[Greenham]

@Marinus-van-Deudekom

Here is an example of what you are talking about. using @Guzt Workflow and using Tracklogs to compare your DESIRED route to the Tracklog I get these anomalies

Notice the gray line is the Tracklog the dark line is my preferred route of travel. Will these Tracklogs be the route the Zumo will take me?

Finally I have this anomaly with a Tracklog/Route comparison.
I've tried all kind of fixes like moving shaping points adding Via points, still get this odd occurrences. The Tracklog is Red, the route is black.

[Marinus van Deudekom]

@Greenham Did you get those anomalys when switching between shortest en fastest?
That can only be done using the Car profile. In the bike profile you don't have that choise.
For planning I stricktly use the car profile.
I compare the prefered route (planned in the Here map) with the TomTom and OSM maps and make shure adding extra shaping points to the route when there's an anomaly. Then in the end when I'm satisfied and the 3 maps are alike I transfer the route to the XT, using the Drive app.
I don't use any avoid items in the planner and I dopn't use any in the XT. That way the route stays the same. Make sure that recalculating in your XT is OFF.
Why: although there's a lot of different opinions on this theme, if you deviate from the route, let's say there's roadworks going on and the route is blocked, and you have recalculate ON, the XT will break free from its harness, the route, and grab it's change to change your route. There's a 100% garantee that it will mess up your rouite.
If you want us to say something about the anomalys you've mentioned, share such a route here and make shure it's set to public.
have fun
