It just gives a ‘turn by turn’ type navigation. It’s sort of alright, but it’s nowhere near as good as having a phone satnav. Really annoying that it doesn’t keep a list of recent destinations so you have to enter your home address every time you set it for home. It does make a nice log of all your rides, showing a route map, distance and duration. You can also set it to ’avoid motorways’ (freeways) which can make some entertaining diversions. Latest version added ‘what 3 words’ support. Maybe they’ll add full screen in a later version? I’m not sure about all the ‘it should have been included’ type arguments - I mean, they included stuff on the GT over the R, and the price is just higher. Overall, I’d prefer a lower list price and a longer options list.
On the helmet front, I attached a pic of my current favorite.
