Another way to mount GPS kit on your dash
Nobody wants to drill holes in their dash, and suction mounts can be unpredictable, leave ugly round marks and often obscure your view. There's another solution, Velcro:
That's a rectangle of 5mm rubber curved to match the dash with the other half of the Velcro. Never, ever works loose even over the toughest corrguations yet is very easy to remove by hand. And no holes!
The unit by the way is an iPaq 312, 4.3" screen, 800x480 resolution modified to boot Oziexplorer directly of an 16Gb SD card. Works a treat.
