Well that isn’t good is it; I often go ‘off route’ without wanting the GPS to re route me. I can’t believe there isn’t a setting to offer the option ‘re calculate or not’
A friend of mine just laid his hands on a Zumo and som very preliminary answers are coming from there.
- No, you can't stop the Zumo from recalculating. No way.
- But it's even worse. It seems that one can't even upload a route from MapSource to the Zumo.
It uses only the uploaded waypoints/viapoints, recalculates everything, and creates a route from where you are to the destination including the all viapoints. Makes it indeed tricky to upload a route running in south Spain while still in Sweden....
This means that the Zumo is probably not fit for anything but taking you from A to B. I have a set of 20 routes for one week of travel in the Alps that was used at a couple of organized tours. Total number of bikes was 40 out of which 2/3 had GPS navigators. The routes proved to work fine on SP3, SP2610, SP2720, Quest, Quest2 and 276C. Map versions used where 4, 6, 7 and 8. There where some issues when compiling the routes for the map CN4 but in gereral all worked fine.
But there are huge problems when uploading the 20 routes to the Zumo.
Due to the rather large number of map bugs one needs the power of MapSource to fix all issues. The Zumo seems to work fine only when the map has a perfect coverage of the entire area. And that is seldom the case in Italy.
Maybe, given time, we will sort out how to force the Zumo to follow the uploaded routes but for the time being the (premature?) conclusions are:
- Zumo is not a good choise for vacation travel.
- Zumo is useless where the map is poor. Portugal, Slovenia, Off-road, etc.
- An old SP2610 is a far better MC-GPS than the Zumo.
- Even a stoneage SP3 is a better MC-GPS than the Zumo.
- The Zumo is a better MP3-player than the SP3.
- The Zumo is, by far, a better MC-GPS than the TTRider.
