Where to stick a toll tag on an Opel Grandland?

Where can you place a toll badge on the windshield of an Opel Grandland GS electric? The entire windshield is covered in heating wires, and there are no black dotted areas where you'd normally place a badge.

Or wouldn't the heating wires interfere with the badge? I haven't received a satisfactory answer anywhere, not even from Opel, where it simply says, "Just stick it somewhere on the windshield, it'll work."

Thanks in advance for a reply

Hi Eric,

The heating element should have no effect on the toll tag being read at all, but if the glass has a layer to help reduce noise etc. that can have an effect. 

Near the very top and as close to the middle as you can ususally works, but no harm trying a few options manually (with a passenger holding the tag in place) to ensure the chosen location works.
