Re Stani's original post. Maybe I am too easy going but I havnt changed any alarm sound levels. I am happy to tolerate the default settings .
The warning display not to fiddle with things whilst driving switches itself off after only 4 seconds. If you cant bear to wait that long simply press the button. I think its more annoyance at being repeatedly told something you already know.

But the next driver may not actually be you. They wouldnt get the warning if you have disabled it. And unfortunatly experience has shown there are many idiots out there who need to be told such things, even if they chose to ignore the advice.
I find indicator volume about right when travelling at speed, maybe a little loud when stationary, (when the car is otherwise silent) . But tolerable.
I think you have got it the wrong way round regarding Toll Roads. Toll roads, vignette roads, motorways, unpaved roads, U turns etc are all "Avoidances" . You tick the box of those you wish to avoid. Unchecking a box means you are happy to use them. This is the same on the new 'Here' satnav and the previous Garmin.
Personally I have no issue with the speed alarm. I soon developed 'selective hearing' . I subconsciously pay attention to the alarm if I inadvertently exceed the limit. The other day the car behind me was a police van, and despite being extra careful to keep to the limit I inadvertently exceeded it by a couple of mph now and again . The beep was as useful warning.

If I deliberately chose to exceed the limit (If I think the real limit is actually higher, or occasionally a bit of

) its easy enough to ignore the maximum of 3 beeps which stop once you reach your chosen speed , naughty or not.
