Anyone know what the battery drain implications are between the tone alerts + flashed up navigation directions when using routing, and the need to regularly display a track?
Presumably, when track-following you either need to have the display on full time (so you can glance at it to check you're OK) or keep flicking the display on whenever you feel the need to check (and maybe find you've missed a turn 5km back!). How do you chaps use it?
I must admit I am finding the degree of ultra-precise faffing about needed to twiddle my auto-routing directions to precisely match the routesheets is increasingly exponentially, and the associated hair pulling is likely to soon run out of raw material! No doubt those much wiser than me have already realised this, and that's why they stick to following tracks!
