Hmm, that's rather curious, as I can repeat the experiment - simulated route, select bus and it sends be down the first route, select truck and it sends me down the slightly larger looking but more of of the way roads?
An 'avoid B class or less roads' would be great - anything to avoid the no-doubt-classed-as-30mph roads that you acutally have to bury your card into a hedge to let other cars passed every few minutes. |

Intresting, haven't seen those comments, new here. That does concur with what I've found while playing with local trips.
Another strange thing, the c320 came with a copy of "CitySelect Europe v7 c320" the routing with this gives a different route than the GPS  |
This may be because the road speeds are customizable in CS giving more varied options

Hey, don't shoot the messenger - I'm only repeating comments by Garmin that were posted here - and that comment was pretty adamant - whether it was truthful, knowledgable or factually correct, I cannot be sure, but nevertheless, if you are to buy the word of a Garmin representative, and that it was accurately quoted, the vehicle selection has nothing whatsoever to do with the roads chosen, merely the estimates for the arrival time, and the estimates for the time / speed on certain types of roads.
I've never personally tried altering my vehicle selection, with a view to any alteration in route. |

| I drove from Newcastle to Bamburgh the other day. When I was established on the A1 the i3 told me to stay on it for 43 miles and the read out said A1 to B1431 which was the road I expected to take. However, when I got near Bamburgh it took me off the A1 onto a very minor 1 track road. I ended up in a field, though I think that may have been due to reacting too quickly to an instruction to turn without checking map. It got me where I wanted to go and when I came back took me the same route. On the return trip I came across a large farm vehicle and had to reverse some distance in the dark. The unit did appear to know the better route until I got up there so presumably it wouldn't be too complicated to alter the software to use that route?! |

| What is required is the ability to enter average speeds for differing classes of roads. I could do this on my Tom Tom for pda but cant here on my Nuvi. I wrote to Garmin about this and was told I should have bought a differing unit. Some help - NOT..... Surely this is an easy fix. I listed all this on the reply to a another thread.... |

Is this thread still the current state of play?
I still regularly get sent down tiny roads with more grass than tarmac.
I3, V9 maps, version 2.7...  |

the reason you get sent down unsuitable road is because many little lanes in the uk. have speed limits of 60mph so the routing algorythm will use the small roads as falls within its rules

For those with more sophisticated Garmin units try setting the data fields to : Distance to next and Time to next and divide them out ..you will then see why minor roads where you spend most of your time in reverse gear are used in preference to A and B roads

I agree that changing the vehicle type does appear to change the routing. I tried selecting truck and did not notice a difference, and then tried bus, and that seems to have helped with this problem? I think truck might be american for 4WD vehicle or pick-up? |
