Modern cars are fantastic, but not always conducive to mounting radios.
Its easy to take to them with a screwdriver, but modern plastic and resale value really takes a whack!, to solve this with my old car and my icom 706 head unit, I looked wider and came up with the below.
Taking a screwdriver to a windscreen suction mobile phone holder bracket, i was able to convert (this one is a NOKIA brand) this to accept the mounting plate of the icom head. Now i can mount the radio on the windscreen and have it sit on top of the dash, this big suction mount is very stable, no wobble, and has worked well for a number of years.
It also allows quick removal to take the radio away when you get to a car-park, or when the car converts back into the soccer mum shuttle!
