nuvi 310d - jam avoidance?

[davek0974]

Hi all,
i'm new(ish) to sat-nav and have a nuvi 310d/gtm12 tmc.

When the nav shows up a red triangle on a route being driven, does the unit automatically re-route or do i have to look at the details and choose 'avoid' to skip the jam?

I have set 'avoid traffic' in the setup panel.

Do the different colour roads indicate anything particular?

If you get an empty red triangle, this means traffic on your route - you need to go and view the traffic and tell it whether or not you want to reroute.

Another option is to simply go through Where To? and select your destination again.

Both of these will result in a new route being drawn up based on the traffic (the traffic which the unit knows about at the time of the route calculation is taken into consideration).

If the red triangle has a swervy road in it, then by simply selected it it will offer you a faster route, for which you can just select Yes, and it will auto reroute for you.

Yes, the different coloured roads indicate the different types of road, ie minor, local, major and primary route / motorways.

thanks swing,
that helps a lot. It would make more sense to have an 'auto re-route' option somewhere though.

Anyway, its a cool gadget and works well.

on the same topic, with the nuvi set to avoid traffic in the menu, what exactly does it avoid??

is it just stationary traffic, or congestion, accidents or what?

Thanks

It avoids any yellow or red traffic - ie not green traffic.

So, it'll avoid stationary, congestion and roadworks (but only with a delay).

I dont use my nuvi 610 much but have been having a play while sat in the drive and getting loads of traffic info. I've put in routes that go directly through traffic problems that are logged on the traffic screen. When should I see the red triangle? Should it tell me as soon as it has calculated the route or will it only appear when I get close to the incident? If so how close? If I scroll the map to where I know the incident is then it has either routed me around it or put me straight throught it. When it has put me straight through it I can see the red triangle but nothing happens when I touch it. Is this because it can't find a quicker route? Also the Garmin website and the manual seem to imply that you should see a yellow diamond on the map screen if there are any problems on your route but I haven't seen anything. Sorry. Alot of questions I know but at the moment I'm thinking of trying to drive into a jam just to see what happens Also I virtually forced the wife to take it with her on a journey explaining how great it was and it would divert her around traffic blah blah and it took her smack into a jam on the M25

Should have read 310.

Right, if the unit already knows about the traffic before you calculate the route, and IF you have it set to Avoid traffic, then it will try it's best to route around traffic (yellow and red delays - not green), and you will then not normally see the red triangle. The red triangle indicates your current route takes you through (or past the end of) traffic (ie you calculated the route before it knew about the traffic, or can't avoid it).

If you press it, it should come up with the list of traffic on your route. If it is not doing that - what software version is the unit (System, Settings, About)?

You won't see the yellow triangle - that's the US symbol for traffic - you will see the red triangle.

There are a number of reasons it would have taken her straight into the traffic jam:
- No traffic signal coverage
- She didn't notice the red triangle, select the traffic, and route around it
- The incident had only just occurred and not yet sent out
- The incident wasn't really that bad, and hence as far as Trafficmaster were concerned, there was no traffic.

Thanks Swing. It is set to avoid traffic and it will divert around when it first calculates the route. Where does the red triange appear on the map screen. is it at the side? At the moment I can only see a red triangle on the route where the actual incident is and if I press it nothing happens.

If you are on the main map page the red triangle will appear just above the distance to next turn (which is in the bottom right hand corner) - it's much larger than the red triangles marked on the map itself (which you cannot click).
