Round 'n' round in circles.........
Well I used the SPIII for the first time in anger over the weekend. just over 600 miles in two days all aided by the GPS on a premarked route done from Mapsource.

On the whole very pleased but it did tend to do some rather odd things, via points for example?

What are they?

I was not aware that when I was doing the route on Marpsource I had added any? But over the 300 mile first leg there were 12 of them?
The odd thing was that it seemed to send me off down a road that was clearly off route just to do a U-turn after the via point had been reached.:confused:

But this is the best one and hopefully someone can explain why. Going down a dual carriageway to an island, GPS tells me to take the fifth exit. But in doing so it would bring me back in the opposite direction again?
So I do it anway just in case there might have been a turning and you are not allowed to cross the lanes in order to make the turn.

But no? I am now traveling back the opposite way to the next island where the GPS now says take the third exit.
Yep you've guessed it back down the same dual carriageway that I was going 1/2 hour before hand?

BUT this time when I come to the island that the GPS first told me to take the fifth exit now tells me to take the third exit which is the correct one? Please explain someone?

Then the headset decided to pack in after just a few miles of leaving home but after a stop I found it was a bad connection in the jack plug. With the headset back in action it made the journey so much easier not having to keep looking at the screen.
The cable from the headset to the GPS has got to be changed for a coiled cable. Job for Mr Farmer I cry:shout
The standard straight cable moves about to much and when at speed, (anything above 80mph) it acts like a skipping rope whipping about all over the place. It also frets on the tank and has resulted in lots of very fine scratches on the top of the tank. All polished out ok, but they could be avoided I think with the coiled cable idea keeping a little tension on it.

On the whole a great piece of kit. To take us from Worcs to Maryport not using the motorways and using only B roads and white roads without looking on a map is fantastic. Mind you it did take us down some "very" dusty tracks at times!!

I've noticed when making routes that it is best to zoom in and have a good look. If you had marked the points yourself you could have done a find point for each and it would not of happened.

So in the future make a route but check it zoomed in before loading it to your GPS. For me its a mapsource problem rather than the GPS
 
BTBR, mine does all of that as well, what fun :( I always check the pictogram of the junction on the display before I commit now, the ‘take the 3rd exit’ stuff is often wrong.
What’s more annoying is arriving at a junction that’s been there 100 years and the GPS doesn’t know about it.

Generally though I’m very happy with it, Norway in two weeks, and I won’t get lost!
 
I've just learned the hard way on my 4 day UK trip... I preprogrammed loads of routes on MapSource, uploaded them, and when you then follow the GPS, make 1 mistake, the GPS recalculates a new route to your final destination, bypassing all the great roads I have programmed.

best is to put waypoints, and go from waypoint to waypoint...
 
What Mark said above for towns. The dual carriageway thing happens when you click the wrong carriageway as a via point, not always apparent when zoomed out in mapsource.

To stay on route disable auto recalc or at least set it to ask first then only if you get really off route let it take over.

GPS is always fun and games when you start out :)

Thanks for the very prompt replies and I guessed that it was a Mapsource issue. Like some have already said its best to zoom in and check the out first.
The other really odd thing that it did was to divert me of a main road down a dusty cart track which was just big enough for the GS to fit :D
Some ten miles later I then popped out on the main road again, God knows if it was the same one or not? Now I cannot recall adding that route? I can only think that because I had used the route tool from one town to another it just selected the fastest route. Not a problem really with that but it did confuse me as to why at the time. :confused:

Regarding the headset cable does it have to be screened?

I have found some coiled cable in the RS book that looks like it might fit the billb - RS part number 365-234 250mm coiled, 1.5mm extended, book 1, pg 263. Can some tell me if its suitable or not please?

One last question, what size is the jack plug that goes into the rear of the SPIII?

BTBR - the incident with the roundabout may well have been that, when you clicked the 'via point', it positioned it on the other side of the road (was it a dual carriageway?). Betty therefore steered you to the via point and then back on your route. Via points are the points that you click on when setting the route on your PC...

Having checked my route more closely last night on the PC I can see where I went wrong.

As everyone has suggested, when I was doing the route I was just "clicking" on towns that I was passing or junctions that I needed to pass by.
I did this at the 5 mile scale, but after zooming in I can see where these via points came from...........hence I went up two dead ends, four times up/down the same dual carriageway, round one island twice and finally into a public toilet in Holme Firth! :D

Still, a lesson learnt as they say?

I have also turned the autoroute off and have it set as prompt only, lets see what happens now then.

Cheers

OK, so I'm thick - how does one do this? I've been fiddling around for twenty minutes without finding it!

Try page 43 of the owners manual?

The other thing that hasn't been mentioned yet is the "Auto-routing" settings on the preferences part of the set up on the PC.

If it is set on "Shortest route" it will use all the green lanes etc. it has at its dipossal.
If it is set to "avoid highways", it will lead you off the dual carriageway at every opportunity.
Also, even the speed settings will alter the route. Put 70mph on the "residential streets" and see it leap!

Your set up is vital to the route computation.
