Question on aftermarket GPS system

onlooker123 SG

I read the papers that 30% of new cars come installed with GPS system these days.

What are the GPS options for existing cars? Must be professionally installed?

I thought a GPS system would be very useful if driving to Malaysia.

Anybody with experience to share?
