Naviking, Carmax, Toyota: Help canceling journey; entering Long & Lat.

I’m enjoying my new Naviking GPS but I am having trouble doing a few simple things.

I can’t seem to find the cancel journey button. I believe I found the buttons that let you replace one destination with an other or add a stop in between. But, I can’t seem to find a button like the cancel button that is on my Garmin.

Also, can someone share an example of the proper longitude and latitude format? I can’t seem to get it right. I would be entering the longitude and latitude of a place that would be caught on my old Garmin. Thanks
