I first saw this when I loaded Wapping's routes for his Pas de Calais jaunt the other week. I wasn't the only person to experience this. I assumed that there was some glitch in the way Wappers had compiled the route.

But this weekend, I treked up to the Midlands and found that, even though the route was calculated by the Zumo itself, one section of the route was shown as a straight line and all navigation references were lost when I drove the roads adjacent to the staight line.

Reading the Zumo forums, this appears to be a known but occassional problem.

Has anybody else seen it when on the 3.50 firmware?

Not sure what your exact problem is but last year in France my 660 (Nav' IV) would only give me the "as a crow flies" option after setting our destination's postcode...

Usually the 660 gives you 3 options: fastest time, shortest distance, off-road.

It had been pouring down for days, maybe it didn't like water?

:D

Greg,

It happens with the Nuvi 550 too. As you say, even though the unit recalculates the route on loading, and with all the options set correctly, you can end up with straight lines on the unit. Occasionally, the same can occur within Basecamp/Roadtrip/Mapsource. Dunno why.

The 'solution' is to recalculate (again) on the unit, which invariably tidies up the route.

Something very simialr happended on my 550 and IIRC the zumo forums mentioned Mapsource problems. As has been said force a recalculation on the unit made it follow the roads. Some time later it seemed to be fixed, don't know what they did, maybe they fixed a bug in the mapping that both the GPS and PC didn't like.

That's OK as far as it goes, but it doesn't explain the straight route section I had when I asked the Zumo to calculate a route to a destination.

I've pinged one off to Garmin Support - we'll see what they have to say.

No glitches in the creation and it ran fine on mine, despite us both running the latest maps and software on both our PC's and GPS devices, Greg :thumb2

I have though managed to re-create the problem by opening a route (drawn on an older map version) in the latest version. It looks perfect on my PC, as it should.

If I then send it to my 660 it asks me if I want to re-calculate. If I say 'NO' I get straight lines between the via points. If I say 'YES' (fastest route) it is fine.

But, if I open the old route on my PC and then SAVE AS, rename it and then upload it, all seems to be well.

Had meant to contact Garmin, so would be interested to hear what they say.

Greg,

Can you post Garmin's reply when you get it?

I still get this glitch from time to time, even with the latest mapping. Last year, I managed to reproduce the 'issue' on Roadtrip when planning a route to Spain. These odd lines occurred well before I loaded the route onto my Nuvi. Zooming in the closest setting and making sure that the dragged waypoints were on a road made little difference. I then loaded the route onto the Nuvi, same problem. Until I recalculated.

I did take pictures, both on the unit & Mac, in order to tell Garmin, but ran out of steam :augie
