I didnt need the disk to get the mount to stick to my dash

We purchased this because the installation of our satelllite radio failed almost immediately insufficient adhesive on disk to stick on dashboard

Really sticky can use it on the dash and not just the window

I purchased this as the original mount for my xm radio which originally mounted over the ac vent a terrible design

Im not sure about the dash mount im not willing to stick anything adhesive to my dashboard

However the suction cup on the mount itself does not stay sticking to the round plastic mounting disk because the weight of the radio overtime is too heavy

What i did was i just took off the plastic disk from the adhesive which was still stuck on the dash and have been utilizing the suction cup mount itself on the remaining adhesive still in the dash
