The problem doing this is there are different algorithms used by the mapping companies, so whilst you may have thought you had planned to ride on road A, Garmin may think road B is faster so will route you down the one it likes. This is especially true if you have no motorways set in my route app but you haven't checked the no motorways avoidance box on your Nav. To some extend you can avoid this by having more waypoints but as has been mentioned there is a limit to the amount you can have.
I have been fascinated with maps since I was a kid and one of the best parts of my trips is planning the route. I treat the Sat Nav as a dumb device (the Garmin is dumber than most!!) and it's there merely to guide me on the route I want to take. I could do it with a map only but 300 miles of back roads gets tiresome if you have to keep looking at it and frustrating if you're leading other bikes which I frequently do. Most of the problems people have with satnavs is they expect it to do too much, it's merely an aid to navigation. Back to the OP this is why A stand alone sat nav beats a phone (at the moment) Set it on 2D North up and on a GS with a whizz wheel you can zoom l in and out on the fly, know where you are at any given time, make route adjustments without having to alter your planned routing and all without stopping or removing gloves. Yes it takes practice, so get out and ride more!!
Well I'm on 9000+ miles on the new GS I bought in March 2017, so I don't think lack of riding time and practice in using satnavs is the issue! If anything just the reverse, the more you use them the more their deficiencies irritate, and as for zooming in and out and making route adjustments without stopping, whizz wheel or not, this sounds dangerously distracting to me, and possibly enough to get you arrested in some countries.
Even when stopped, having been there and done that, I found zooming in and out to work out an alternative when you need to make a change of route, incredibly frustrating. On one occasion I ended up in a 20 mile tailback to get through the St Bernard tunnel and wanted to work out which way to go to get back to a point where I could take an alternative route out of Switzerland. The problem is that with small screens with limited resolution you have to zoom right in to see names of nearby roads and towns, but then when you zoom out to see the bigger picture of where you are heading, most of that information disappears, making it very hard to put your position into context. Very laborious to plot a route that way - in sheer frustration I eventually phoned my son and got him to find me a route on Google maps on his PC and give me a list of key towns to head for.
With my current system I could simply go for a coffee break and while stopped plot a new route, or make a new version of the existing one in the MyRoute routing module, and immediately load it into the satnav app on the phone - this would probably take about 5 minutes, and I would then be good to go. On the recent tour of Andalusia I have just completed, I left the Garmin at home and used the MyRoute Navigation and routing app. Every time we wanted to move on I just booked the next hotel on booking.com and then created a route taking in the roads and places I wanted to visit en-route. Very quick and easy, and immediately available to load into the satnav app.
