Navman icn 520 maps
The NavMan iCN is mounted in the vehicle using a windscreen suction mount. This is a 2 part mount consisting of the suction section which connects to the iCN using a ball and socket joint. In use this proved to be very stable. As this is a proprietary Navman mounting system there is no flexibility to explore other mounting options.
