Mercedes-Benz uses two very different types of material for their dashboards. Their most common one is the Basic (High Relief) and a Nappa (Smooth) finish. We carry this in the older EZ-Pass, pre 2012 square style transponder as well as the newer I-Pass, post 2012 convex shaped transponder. Our cases attach to the EZ-Pass and I-Pass using two straps the hook and loop Velcro ends. They are designed not to interfere with the signal to the reader. They also resist fading in direct sunlight.
We currently have the Basic product available for sale. The Nappa finish will be available in February, 2017.
