Running an aeroscreen 7, and needing my satnav tomorrow I have just fabricated a bracket and plate which attaches below the dash on the passenger side. Basically it is an aluminium upper clamping piece and lower plate, curved to match the profile of the dash cross bar with a thin rubber coat where it clamps to the rail. There are two holes in the flange which carry 6 mm bolts through the bottom plate to wing nuts which clamp both parts together, for easy attachment and removal. The plate is angled to hang vertically, and the Garmin sucker attachment mounts onto that. This is a quick and dirty fix for tomorrow, and Mk 11 will be profiled to the size and shape of the Garmin mounting. The green background is to match the car - Mk 11 will be matt black!
