Hi Mal,

The GPS would only need a remote aerial if it is located in a spot that is shielded from the overhead satellites.

I have a Magellan Meridian Platinum handheld, which snaps into a cradle mounted near the gear selectors on the centre console. Have never needed an external aerial and it includes a memory card slot for additional maps.

Your other specification however is one woth thinking about. (Large Screen)
No hendhelp unit has a really big screen, however, most can be connected to a laptop for better moving map display.

Failing this, you may like to investigate an "In-Car" navigation unit which certainly has a larger screen, but is less portable.

Here is a couple of WEB sites that may be of help to you.

Prestige Comms
GPSOZ

and of course there is the ExplorOz Shop.

I needed the same things and bought a Magellan FX 324 MAP Colour. Can only load Magellan maps , but no hard drive to drop it's guts . Screen incredibly large and clear and I have poor eyesight .
Very pleased with it .

Hi Mal B,
