Eric,
A cheap method of holding a scanner in place is velcro. Take a look at the back of the 96 in the
middle photo. You'll see some of the soft side (not the prickly hook) velcro on the back of the scanner at two locations.
What I have done is put the hooks on console then place the scanner on them. With the scanner on its back, I can look down and see the display fairly easily. Holds for most cases and is easy to remove the scanner.
Putting the soft side of the velcro on the scanner makes it more comfortable to carry the scanner if I want to take it out of the car.
They sell velcro that is preglued and I've used this for a number of years. Every so often the soft side of the velcro needs to be replaced as the threads get worn down and don't hold as well. The hooks never seem to wear out.
Notice that I have not done this to the 396, that #$%%$% swivel connector preclude this. The 500 had just come out of the box, but has been modified like the 96.
