Can I buy a nav unit for my 1998 4.6HSE? If so how or where? If not factory, any other suggestions?

My two cents

Shop around and check to see if you have a metalised windshield. If you buy a GPS, that antenna gotta see some sky and those heated windshields block the GPS signal.

Take a good look at the Garmin Palm PDA and the StreetPilot. Both are excellent products and have great features.

I have the heated windscreen on my disco, and I use DeLORME Street Atlas 2005 on my ThinkPad with the GPS receiver placed on the dash. Works flawlessly.
