Thanks. It's works fine with my Montana.
Some have correctly queried if active routing works in V4 . The answer is , yes but given this gmapsupp , it works for only the 3 types of Cycling. I have analysed the img and TYP file and both contain no info regarding walking hiking and climbing. Interestingly, the contours are less detailed
I added in post n.4 some TYP files for this topo map better readability, I got them from sorcieremonique forum.
You can test them and give feedback.

Spoiler: Replace TYP file in img file
All links to download Topo v4 in post#1 and post #2 are dead.
