I placed the soft removable cradle insert inside the mesh compartment and slipped the GPS in there. That way the GPS is very well padded and snugly secure. It doesn't fall out when you open the case. My bulky power cord (Nuvi1390LMT) fits in the open compartment and shouldn't fall out if you open the case like a book. There's some room to spare in that open compartment, but I don't know about fitting the windshield mount in there. I keep the mount in my car's armrest compartment as it isn't damaged by extreme hot or cold weather. Perhaps if you take the mount apart and/or discard the soft insert it would fit in the case, but I wouldn't compromise GPS protection to fit the mount in my case.
Delivery is fast, thank you
It is a very good device and the application is superb! Customer service is the best I have ever encountered!
Well Worth it!
