I too am running into this symtom.  My route below is a big long and very curvy route, but it is not 10+ hrs long.  Importing this into inRoute (since CarPlay is not usable for me) it reports a route of about 7hr 40min.

In working with the map provider to improve the estimated durations.

Guido, similar issue here, I noticed that when i took A roads, ETA was about right, but today on smaller B roads, using curvy, the predicted average speed was below 30km/h, I’m not that slow….

cheers,

Laurent

Interesting note

I have the same 4.04 scenic version on my phone as iPad. Both have the same iOS version 17.7. The two give different times for the same route with the iPad being accurate and the iPhone overestimating how long the journey will take. Same route and distance for both.

Best wishes

I had another user with this problem. Also creating route on iPad and viewing on iPhone. So far I have not been able to reproduce it.

How did you create this route? Was it an import from GPX? Or was it a curvy route generation perhaps? Do both of your devices have the offline maps installed for the region?

Quote from Rods on 07.11.2024, 08:21

The route had been shared by a Scenic friend. I edited it (hence the copy) in the same way using the phone and iPad. Both have the relevant offline map.

Do you want me to try generating the same route with both?

Generating a route using the ‘standard’ option between the same two start and finish places gave different routes and very different times.

That's very weird. Are the routing mode settings exactly the same on both devices? (If you tap the motorcycle icon... are all sliders and toggle switches on the same settings?)

Quote from Rods on 07.11.2024, 09:20

Yes

Quote from Guido on 07.11.2024, 16:50

I can't reproduce this issue. I must be doing something differently than you. But what? How can I reproduce this issue?

Here's what I did:

On my iPad and on my iPhone I made sure to have the same iOS version, and same Scenic version, and on both offline maps for 'England' installed.

• On both devices: tap the routing mode button and make sure sliders and toggles are set to this:
  
• Go to plan mode
• Tap search button
• Enter 53.531818,-1.635514 in search bar
• Select search result > add to route > "Start Flag" in toolbar
• Tap search button
• Enter 54.613605,-1.098762 in search bar
• Select search result > add to route > "End Flag" in toolbar

Results:

There is a 1 minute difference in duration, but I suspect that's due to rounding of the coordinate decimals. The route looks the same, distance is the same, and duration I consider the same.

I see it, but find it hard to believe it. 🙄

I need to be able to reproduce this reliably so that I can report this to the map provider.

What is your iPhone model and your iPad model? And what iOS version are you running on them?

 

I need to try on physical devices now instead of the simulators like I’ve been doing so far. That’s the only remaining thing I can think of.

Quote from Dae on 08.11.2024, 07:04

@guidomm - I know you are starting to think you’re going crazy with issues you can’t reproduce, so I followed your steps exactly on my iPhone 15 Pro Max (iOS 18.1) and iPad Pro 11” 2nd Gen (iPadOS 18.1).

I too get different results, despite running same Scenic (4.05(1)). I circled the obvious difference.

iPhone:

IPad:

@guidomm - further to the above, I also tried on my other iPad Pro (12.9” 5th Gen) and my MacBook Pro (M2 14” 16GB). All running 4.05(1).  All on latest iOS/MacOS/iPadOS.

The iPad Pro 12.9 agrees with the iPhone (96 miles)

The MacBook agrees with the iPad Pro 11” (101 miles)

iPhone SE iOS version 17.7

iPad (8th generation) iPadOS version 17.7

both running Scenic 4.04

Quote from Guido on 08.11.2024, 11:13

Nope. I'm not going crazy. Just did the same on 5 different Scenic installations, and I get EXACTLY the same route. All devices running latest iOS / iPadOS / MacOS. All devices same version of Scenic. All devices England offline map downloaded. I also tried without offline maps and on a device running iOS17.7. This resulted in a 3hr59 minute duration.

So... what can cause this? Well... i have 3 theories:

1. When you are doing this, Scenic is not using the routing mode it's indicating. If that's the case, then there is a bug in the Scenic code, which is triggered by you doing things in a different order / different way I am. But what? (please check video)
2. You are doing something different in entering/selecting the coordinates causing slight differences in the start and end coordinate. (please check video) Although possible, I believe unlikely. A small difference in a coordinate should not have that much influence on the route.
3. Your Scenic installations somehow use a different version of the maps and/or revert to the online calculation. (even though I get EXACTLY the same route without offline maps too).

Here is a video showing exactly what I'm doing: https://drive.google.com/file/d/1PgchWf6HCDgNY6YmAP3G_tKkAX5gqa0l/view?usp=sharing
Please note where I tap, the order in which I do things, etc. It can be the smallest difference.

• Start coordinate: 53.531818,-1.635514
• End coordinate: 54.613605,-1.098762

These are the results of my 5 Scenic installations. I used @rods usual routing settings.

@guidomm - Your clicks/taps are **exactly** the same as mine, but with one difference.  Where you type in the co-ordinates, I copied and pasted them from further up this thread to ensure there were no mistakes.  I did this on all 4 devices though, so was consistent across all my testing.

All devices have whole of UK offline maps downloaded and up to date.

I’ve repeated the test on my iPhone and MacBook using the settings you’ve just posted.  iPhone is 99 miles and 4hr 0m, MacBook is 104 miles, 3hr 17m.

Quote from Dae on 08.11.2024, 11:52

Ok. I uninstalled and reinstalled on my Mac and iPad 11. Both now agree with the other two devices.

It’s weird, as all devices had 4.05(1) and up to date offline maps. I wonder if something has corrupted at some point as all devices have had every beta ever released installed on them. Maybe remove and reinstall fixed it. They certainly all agree now, albeit that means I can’t do any more testing as it’s no longer broken.

Quote from Guido on 08.11.2024, 11:56

I was just about to ask you to do that 🙂. Thank you.
At least now I know that it has something to do with map versioning and a map update not being the same as a fresh install of a map.
The search continues...

Thank you!

 

Quote from Karlchen on 08.11.2024, 13:32

Bei mir waren  bis gerade die Zeiten bei gleichen Routen bei gleicher Einstellung und gleicher Versionen auf dem iPhone und iPad unterschiedlich,

Nachdem ich dann auf dem iPad die Offline Karten aktualisiert habe, waren dann beide gleich.

👍

Beste Grüße

Quote from Rods on 09.11.2024, 11:37

I uninstalled Scenic from the iPad (which was the one disagreeing) and installed version 4.05, together with the relevant offline map.

Result: we all agree 👌

Quote from Guido on 09.11.2024, 11:44

Still quite worrying. I need to get to the bottom of this. A route should be the same, independent of offline maps being updated from a previous version or installed clean for the first time.
