Hi Gerd,

 > If I comment the roundabout block  in the lines file

See my first mail, I have tested roundabouts. Commenting the roundabout 
block clears problem, but if you instead change objects 0x0c into some 
other road, then problem remains.

More precisely, I think route is correct, when roundabout get the same 
object as main road, but if roundabout is a different object (not 
necessary 0x0C), then calculation is wrong. Maybe reason is a turn angle?

In my test detours contain roundabouts too. And if I set avoidance to 
roundabouts in BaseCamp, then detour changes, which suggest that 
roundabouts aren't the main reason of detour.

I think mkgmap processes tag "junction=roundabout", even if there is no 
roundabout object 0x0C. After commenting the roundabout block, avoidance 
in BaseCamp still works. But avoidance doesn't work with following line 
in style:

junction=roundabout & highway=* {delete junction}

Side note: there is no verification of "class=" value. If I set 
"class=6" then mkgmap crashes with array index out of bounds exception.
