GPS with ability to dynamically change route on the fly?
I know, I know….another GPS question.
However I'm not looking for opinions on which one to get. I've spent the time reading & researching. I have an idea of what I want, I just need some insight on what's actually capable. I've searched around for this, so apologies if the answer is already out there. I just don't know how to word this for a search:
Ultimately all I need from a GPS is the ability to compute and give turn-by-turn directions from point A to point B. I don't want to use my phone. I've done it, I don't like it. NO.
Past this – I don't particularly need other features but I won't say no to them, and while I like the idea of an eTrex I want something cycle-specific with the intelligence to give turn-by-turn guidance and not just a breadtrail.
Here's the big ask: I want to be able to change the suggested route, ideally on the fly and if possible, on the GPS unit itself. If it has to be on the phone, no problem, as long as it's intuitive and/or simple. For example – I'm at point A and have the computer route me to point B, but I don't like the route that's suggested – I want the ability to modify the route – either sections, or the entire thing. Kinda like in Google maps how you can click on the route and drag waypoints around to go on roads you know work better for you. Is this possible on ANY cycling GPS unit?
I totally understand and am ok if I have to use my phone to do this. Or if it's not possible, my other thought was simply using the cycle.travel app, creating a route on the fly, and then sending it to the GPS unit. Would this work with any of the following units without internet connection? I like the idea of the GPS computer being able to do routing/rerouting on its own, however if this use-case is better done by using an app on my phone and sending the maps over to a unit, I'll just do that. I just want to make sure whichever unit I get can accept the maps I'm sending and give decent turn-by-turn navigation.
Units I'm considering, in order:
- Garmin 840
- Garmin 540
- Wahoo Elemnt Roam v2
- Lezyne Mega XL – maybe, sounds like this is breadcrumb-style only. But it would save me some money and is simple which I like.
