Don't have my copy of the approach chart at home but from memory the basics are:
"Cloud breaker" LOC/GS at about 4 1/2 degrees until break out altitude around 1500 ft agl (lower with special permission from Austrocontrol).
Visual curving approach following lights mounted on town rooftops to runway.
The initial descent is right down the Inn River valley through the usual cumulo-granite. The problem is that there is often a thick cloud layer hence the LOC/GS with high decision altitude. CAE have modelled it for the CRJ sim so it might be on one of the Microsoft sim web sites.
