Sounds like loom working fine.
One thing I have noticed, when starting car, refrain from pressing button for about 60s, else it stays quiet. Give that a go.
As to junctions, its designed to warn you of traffic 2 jncs ahead or 10miles, whichever is less iirc.
Or do you mean you have to be right on top of the motorway before it gets a signal? That'll be aerial, but mine is around 100-150m. The one on Mrs TB's Rover is about 3 times that, but it was easy to get an optimal aerial position in that
Ok ill try the 60 secs thing. Probably pressed it 50 times by then usually, so far. Im sure the novelty will ware off soon. :-)
Re the 10 miles thing, i am easily within that of the m4. Probably within a mile as the crow flies and 2.5 miles from junctions 10 or 11. So should be well in range but its well built up so could be shielded by hourses until i get to the end of the road where it opens out a bit.
First peep i get is a bleep, well, more of a meep actually, as i get within 100yards of the 329m junction,( dual carriage way which leads to the m4) and have to press the button to get the info even though its set to automatic mode. Next jcn is m4 and can be 2 or 3 miles down m4 before it is mentioned. I keep pressing the button for an m4 report before i turn onto it and it only talks of the 329m. Even though i have been on m4 for 2 or 3 miles.
Having said all that i wonder if it only pipes up automatically when it has something to report. When passed the last junction ,5, before the m25 at 4b it told of standing traffic on the m25 and reported the 404 being clear, something it would have been nice to know when at the 404 junction at junction 9. But thats the limits of the system i guess, so it does seem to work as designed, as you say.
All would seem to suggest i've been hammering the button, of my new toy, like mad to see if its works, and as you say,thats keeping it quiet.
When leaving Chesham and not touching(forgetting) the button as you suggest, it then worked fine when i got near the m40 and wanted info.
Will see if it settles down as the novelty wares off. :-)
Cheers
Chris.
