I was reading through this post, but have neither the Scala or a Montana GPS on my bike. The idea of a choke is a good one. I found that it helped me in previous setups on my Dakar and a GPS system.
If you have a friend who is an amateur radio operator "ham", ask him for a type 34 snap-on type ferrite bead or two. Wrap any wires leading into the Scala and the Montana in them, snap them shut, and see what happens. Sometimes any wires running into units like these act as antennas and can pick up unwanted signals that will screw up the unit. hope this helps.
