GPS/ NAVIGATION

Forget all about ebay, I have read where people get a gps from there, the problems arise (and this is for Garmins) when the purchaser tries to register it, updates, codes etc, and no warranty, gawd damn it the price has come way down, go and get one from a reputable dealer and get the after sales service,

I won't go into the pro's and con's of brands or which retailer to buy from.
7" screens are fairly big and can be heavy. Extra weight on the mounting bracket, not usually as bright as smaller screens and could cause problems with forward vision.
I think 5" is a good compromise.
Having said that, I bought an unlocked 5" unit on ebay, runs windows CE 6.0, SIRF IV chipset, 2G internal flash memory and now has Oziexplorer maps loaded.

I bought a hema navigator 5 which I used on my 8500km trip from Katherine Adelaide Melbourne, through the Snowy tracks looking for the huts, up to Bourketown and west back to Katherine via the Savannah track. It never missed a beat took me through the major towns and missed all the toll roads, will be using it through the Gibb River road next month, good thing is you can load your own maps via Oziexplorer plus get memoryMaps as well. If you buy them from Ebay you have trouble with warranty.
