i think the 520 , 620 / 6200 go pros are all brilliant sat navs
i like having my whats app messages read out to me
i like not having to touch it , i just say the passphrase and it talks to me and asks where i want to go
like recent destination or a favorite place or even a new place , you just have to say the address and it plans the route
i only recently found out that is has that amazon alexa thing built in , or it might be google now
say for example you wanted to go to have a pizza you just say the passphrase , say activate phone say you want a pizza and it will read out several nearby pizza places , you choose one and it plans the route
but you could say anything , like tesco , sainsburys or any firm or shop or factory etc and it plans the route
once its plugged in at the start of the duty , even with multiple drops , you never have to touch it again
