GPS with "fewest turns" option

Although I can't say I've seen 'Fewest Turns' option, there are similar Navigation options available on Sat-Navs. As a general rule Sat-Navs try to plan a route that goes up in road size and then descends again in road size near the destination, I quite often select 'Avoid Motorways' unless I am travelling hundreds of miles, because I find Sat-Navs seem to go out of there way to get to a motorway only to leave it one or two junctions later, when it's not worth the bother. The kind of Navigational options I have seen include :-

Avoid Unpaved roads / Tracks
Avoid Changing roads
Minimize Turns

Although some of these are more common on Smartphone Navigation Apps.

There is quite a selection of Voice activated Sat--Navs available, including :-

Garmin Nuvi 2597
TomTom Via 135
TomTom Go 510

 

I think 'Minimize Turns' is what you are looking for, I placed it last on the list because I have only seen this on a Smart Phone Apps. the User manual for the 2597 (Link HERE), only seems to say this about changing routes (Page 8) :-



You could plot / edit a route on a computer and then download it to your Sat-Nav, but that is a bit of a long winded way to get what you want

 

I am sure I have seen 'Minimize Turns' in the Waze App. in the past, however I think the version I have on my smartphone must have updated itself, because I can't see it now, there is a website that describes it here (Click link)



BTW
If you are thinking of using a Smart phone App., it's worth remembering that although Waze uses on-line maps, there are Apps. that download maps to your phone so you don't need a link to the internet to use them, i.e. no 'Air-Time', they include OsmAnd and MapsMe
