Agreed on the pointless route choices, I usualy set it to walking then give it a quick once over to check it makes sense.
My edge 800 does navigation, but it’s not very good, it needs an option to avoid dual carrigeways.
Garmin car sat-nav is the worst though, it’s horrible compared to tom-tom. Things like not being able to tell it that there’s a road block in x-miles might sound like a minor inconvenience untill you tell it there’s a diversion, turn off the motorway, only to find it just takes you on a very convoluted detour to deposit you right back at the road block.
It treats Scotland and Wales as a seperate countrys, so to to make a trip accross the border you have to go back into the menu to change country before typing in the place name. Even if you’re only a few miles away.
No option to navigate to a generic ‘town center’, really infuriating if you’re arangeing to meet mates for a ride in some tiny village with instructions like “meet at the vilage green” because it won’t accept anything less than a street and house number.
Village with less than a few hunded inhabitants, won’t be in the database, again useless if moutinabiking in the middle of nowhere.
Find the nearest petrol, yes it’ll do that, but it won’t be in the direction you’re going, if you’ve just past one it makes you do a U-turn. Tom tom finds the one with the least detour from your route.
And I’ve lost track of the number of footpaths/rivers/clif edges it’s tried to send me allong/through/over.
Whenever I see somethign on the news about sat-nav goign wrong, i reckon it’s safe to assume it was a garmin.
