After buying my TomTom more than a month ago I have been using it mounted to the windshield using the mount that comes with it. It is a bit distracting being so central in my view, and I’ve heard stories of cars being broken into when the windshield mount is spotted (GPS units are high value and portable).
So finally I have my TomTom mounted where I planned – I bought a new dash trim piece (to avoid trashing the original) and my work colleague drilled a hole and glued a bolt in the back of it. Then he modified the original windshield mount by cutting off the suction bit, and we fitted it to the dash trim piece.
After that, I had MINI of Peabody swap the pieces over (thanks Brian!)
Now it’s much more out of the way, and not so easy to spot from outside.
I’ve found that TomTom still picks up the GPS but is less sensitive (seeing only 5 satellites instead of 7 to 10 when mounted on the windshield) – but next I will wire it to the car and install a booster antenna which will complete the install.
