nav IV annoyance

I am playing around with basecamp and my bmw nav IV. Pretty new to the program, but I'm getting it figured out, and enjoying the learning process. However, there is one annoyance that I have not been able to overcome. I build my route in basecamp, then transfer it to my nav IV. All is well, except if I want to look at the route on the gps, I have to disconnect it from the usb port, replace the battery door, and wait for the unit to boot up. basically, the gps won't allow me to use it if it is connected, or if the battery door is not installed. If I want to change or modify the route, this becomes very frustrating and time-consuming.

My question is whether there is any way to bypass this function of the gps. I would like to be able to simply look at the gps screen without the hassle of unplugging, closing battery door, booting up, etc. etc.

Any suggestions would be greatly appreciated!!
Thank you.

 

Had a feeling that was the case. I was hoping there was a way to get around it, but it doesn't sound like it. I'll just have to live with it, I guess. Thanks for your input!!
