Sounds like the same thing in their mobile app. As you say it's pretty accurate from what I've found with their apps (much more so that Google or Apple maps) but it's pretty useless for a bike. When you say you leave it off, is there a setting to turn off the traffic feature or do you just not connect your phone? I'm assuming the speed cameras don't need your phones data connection?
Also, what's Tyre like?
Have you used the option that lets your plot a round route specifying key areas, twistyness and altitudeyness? (They are words honest...) Twisty roads I have used a few times from my phone via my intercom and tend to find it's pretty good if you don't select max twisty (hello dirt roads).
Yeah the speed camera thing is offline, it's stored in the device like the maps, there's an update every week or 2.
Correct - I just don't connect my phone if I don't want traffic, you can answer calls via the tomtom but it's rare I get any when riding.
The 'plan a thrill' option is pretty good, it does a round trip and you add stops - you can re-order the stops on the device but you have to click on them in the order you want, which when you've done a 200 mile route on tyre with 40 stops (that's how tyre works, you place markers and the tomtom finds the route between these markers) and you want to add a single stop halfway in to stop the tomtom from choosing a side road when you want to stay on the main road, it's easier to add the stop in Tyre and re-uload the route rather than tapping on all 40 stops.
I've just tried a route putting 3 stops on a decent route than I know is good, and on the least windy option it's picked pretty much the exact route I would take. In Kent there's not many decent roads so somewhere with 'proper' roads it could well find you some hidden gems.
The maps can be a little slow the zoom/load etc, but nothing major and when you're riding it's not a problem. And there is a lack of detail on the maps - if someone ever made a satnav with proper google maps on it that would be incredible. As it is, you still need google maps to find stuff easier, hotels etc.
I don't mind Tyre at all, once you use it a bit it's very simple - just pick your route, place a marker - and if you need to fine tune the route by dragging it, it automatically adds in a marker for you.
Oh and battery life is great, I don't turn it off, I just put it to sleep when not using it - it's been sat on my shelf for about 3 weeks and the battery is at 50%.
