Car Windshield Mount Suction Cup Holder

I previously owned a Garmin Nuvi 2595LMT and recently purchased a Garmin Nuvi 2689LMT. My problem is that I use the Windshield Mount Suction Cup Holder with a Dashboard Donut and the Nuvi 2689LMT clearance is minimal with top of the Dashboard Donut.

My observation is that:
Car Windshield Mount Suction Cup Holder
1. with the Nuvi 2595LMT, the Car Windshield Mount Suction Cup Holder supplied measures 2 ½ inches from the suction cup to the top of the ball shape attachment point.
2. With the Nuvi 2689LMT, the Car Windshield Mount Suction Cup Holder supplied measures 3 3/8 inches from the suction cup to the top of the ball shape attachment point.

I am wondering what is the measurement of the Car Windshield Mount Suction Cup Holder that comes with the Garmin Nuvi 2789LMT?
Is there any other 7 inch display GPS that has a larger Car Windshield Mount Suction Cup Holder that will work with my Nuvi 2689?

Thanks
