Does this unit support Satellite Navigation or GPS

I have a 2003 Toyota Corolla 180iGSX, made in South Africa, The car has an integrated stereo (radio to South Africans) system. The system has the following buttons:

*Guidance
*Reroute
*Menu
*Trip/Navi
See http://www.icon.co.za/~i30003097/misc/radio.htm

The unit gives basic fuel consumption, average speeds etc,

My Question is as follows- Does this unit support Satellite Navigation or GPS as it have the buttons to do so, and if so how do I activate the system?

Hopefully Toyota have thought this through and not placed the buttons on the radio for show?

Well, it doesn't look like it would have satalite or any sort of navigation what so ever.

I'm sure however that the manual would be a good place to check out what the radio does.

Most of us here can only guess just like you what those bottons may do, but it looks to me that the system may be prepare to support an outside GPS or Navigation system. The same way some headunits can control CD Changer.

It looks like it can do more than just play the radio. Do you by any chance have the manual for it? If nor ask your dealer to supply you with one since they know who the manufacturer is.
