That's where I am at, but there's times where I prefer to use Google Maps navigation over the MB system, so I want to mount it.
I am going to MacGyver a couple of approaches for window vs. dash mount to see which might work better for me. It will also let me compare the usability of the MB nav vs. Google on a longer trip to see if I really need to do this.
Simple stuff compared to ABC and brake problems, but I am sure that I will be asking for advice on those in the future.
