I was doing a loaded test ride and found a nice canal cycle path on the digital map. Like the previous post there were stairs not shown. I had to take the bags off and being pre pandemic a couple of people kindly brought the bags up the steep stairs while I carried the bike.
I've only just got into the cycling GPS and have found it has really opened up my local area where I would get lost using paper maps or have to stop a lot more for navigation. GPS on my phone eats battery so it's nice to have the bicycle one mounted to the bike especially as it works with my gloves on.
I plan to take it on the next tour, but will be taking some battery banks to keep it topped up and maybe a solar charger. I'll also take a paper map for that overall view just in case I can't power the electronic devices or they break. Never forget the power of local knowledge. People are often quite happy to point you in the right direction if they can, but can also inadvertently point you in the wrong direction.
