Navman F10 on a bike

I've just acquired one of the above, has anyone any experience of using one on a bike? I've seen an aquabox, but on the website the given dimensions make me think my GPS won't fit into it.

The F10 is sized up at 79 (H) x 110(W) x 19 (D) and the device width of these and others is the concern.

RAM-HOL-AQ3 is too small and RAM-HOL-AQ2 is too small on width Dimensions: Width=2.88" (73m) , Height=5.75" (146mm), Depth=1.88" inches. RAM-HOL-AQ6 (the gps version) has internal sizes of 6" (150mm) x 4" (100mm) x 1.75" (43mm) and attaches to the mount with a round base at rear, RAM-B-202 as this is also cable access route.

Thanks, any suggestions for the best one to mount the contraption onto the handlebar, or is there a better location?
