What does "Avoid Highways" mean?...

On Friday I needed to go along a Motorway (M3) but there had been a big accident so I thought I would turn on the Avoid Highways and let the i3 get me there. It started off and straight away started directing me towards the M3 (this was not a surprise as the alternative rout A30 is in the same direction) but I knew there was bad traffic so I headed in the opposite direction knowing that you could loop round. Sure enough the i3 picked up on this and took me round and back to the A30 at a clearer point. So far so good... Now the A30 crosses the M3 at junction 5 at this point the i3 tried to direct me onto the stationary M3. Knowing this part of the route I went straight over and the i3 directed me along the A30 until Guildford. At Guildford the i3 took me onto the A3 but then tried to take me off onto the M25 (a longer route) and then at every other possible oppertunity tried to get me off of the A3... So my question is this... Am I going mad or does the i3 considder A roads more Highway like than Motorways? And if so how can you avoid Motorways?

Many thanks

Trev

I have the same problem with my C310
must be a garmin thing it will always try to get me onto a motorway even if I want to just cruise the a roads and Ive tried all sorts of things from changing the faster time to shorter distance Sad

I too have found the Garmin choice of route questionable. The quickest/shortest route for me on any journey out of my house is to turn left for about 400 yards along a single track country road, which then joins another country road that is a lot wider.

The Garmin always tries to make me turn right out of my house which will take me a mile along the single track country road before joining one that is more useable.

Even when I asked it to calculate a route from my house to the nearby decent country lane (the one that's 400 yards away) it took me on a circular route for 3 miles, rather than do the obvious and turn left out of my house to start with.

Hi guys

I recently bought the i3, have spent about 6 hours driving with it locally and I am having similar problems to the rest of you, the route it chooses is quite frankly ridiculous at the moment, I have tried setting it to fastest and shortest route and each time it plots to take me right into the center of a busy nearby town, when all I have to do is turn right out my house and follow a duel carriageway for about 3 minutes and take a B road right to various destinations.

Tried the route on the way back and again it wanted to take me into the center of a town with 20 billion sets of lights and high congestion..... yes very fast..... any idea if I have something set wrong?

Avoid Carpool Lanes and U-Turns are set ON as default.

In my i3 also Avoid U-Turns are selected by default and twice I noticed that when I go past a certain turn ( once on A1-A14 interchange and once in Nottingham) it asks me to take the next available U-turn and directs me to a turn on the road on a dual-carriageway. I complained to Garmin and they told me the following

"I am not aware of any issues with U-turns with v3.1.

Please let me know if you continue to experience issues with this and I will forward this information onto the engineers."

I have V8 maps and 3.1 software with 256 MB card.

i've not had any probs with avoid highways, its always avoided them.
u turn comes up now and again even though thats selected to avoid also.

I'm beggining to wonder if whoever programs the route has got some interest in petrol....

From my house to work there are two clear routes, one along the A27 and one along the A22.

Now the A27 is technically shorter by about 9 miles, but the A22 route is technically quicker by abuot 15 minutes (work that out!).

Now seeing as the I3 has the ability to choose between "fastest" and "shortest" i'm stunned that either way it'll choose the A27.

And why does it not learn the route I choose? And why is it that at one point sometimes it says "keep left" on a road that doesn't go right, yet other times it doesn't bother. This thing either has a mind of it's own or it doesn't.

Thats a point, I assume the i3 does not learn by its mistakes if you chose to take it another way while it's switched on? or does it?
