I use a tomtom all the time in more then one vehicle. My F350 I bought used had a disk installed to the right of the steering wheel, when I use it in that truck I use the short mount to keep the GPS low in my field of view.
I also use the GPS in various tow trucks for a PT job I work as a driver. I have
this mount and it works great. The tow truck can be a chevy, ford, hino, peterbuilt, I can always find the right way to mount it where its reachable. I prefer to keep it on the left corner at dash level and this arm adjusts perfectly.
