I replaced my mount for my screen - not a big fan of the suction mount type. I have the old mount but since there are two different screen sizes on the monitor now I am not sure which one you need. Post a picture and I may be able to help you out. Or you can do something like this....
Found replacement mount for about $35 and shipping ~$10. Decided to wait on that one. Looked at my iPhone holder and found the base part was same size and fit monitor part. $13 prime on Amazon I'll put it to test tomorrow when we start a short week long trip.
