I thought some may want to see my installation of the XRX in my Bonanza. I used a small block of black high density foam to support the bottom and used 2 small clear suction cups (hardware store) in each of the two corners that touch the glass. Both suction cups were glued to the XRX with a dab of clear silicone adhesive and when both are suctioned to the glass, hold the XRX firmly in place.

While the XRX is only 3.5" inches from the side post or the front windscreen I don't seem to have any problem picking up traffic targets in most all directions.
