Great way to mount large GPS

Hi all ,
I bought the biggest GPS that would take maps because being an old fart , my eyesight is hopeless .
Of course I gave the mounting of such a big unit no thought when I purchased it !That would be like a guy reading an instruction manual .
Finally I worked out a great method that looks good ,does not damage the dash , is stable and very easy to view and work on .
I have a "fitted" carpet like cover on my 100 TD dashboard . I stole my wifes thin white nylon cutting board , located this under the cover , then bolted the large GPS cradle through the carpet to the cutting board . To stop it moving around , I glued to the bottom of the carpeted cover , that mesh non skid rubber sheet you buy from Clark Rubber . I used contact adhesive for this . It seems immoveable now , but the big test will be when I get on the corrugations . If it moves , then I will have to use that sticky velcro tape to tie it down .( I'd rather not though)
You can't see the cutting board which goes all the way to the windscreen to give it stability . I imagine the GPS would be seen as cutting down my vision a tiny bit where it is in the middle of the dashboard , so to keep the law happy I will only put it on when I go bush .
The GPS is a Magellan FX324 colour map and I have loaded maps of all of Aust into a number of storeage cards which can be easilly interchanged . I did not want to rely on a hard disc computer as they crash to easilly . The maps may be better on a laptop but I went for durability .
Willie .
