Types of stereo system?

[Blenko]

I have JUST bought a 61 plate insignia, 160bhp sri model.. it has the cd500 fitted, I've seen that there's lots of different types but what do they all do that's different?

Also is the only way to update my navigation maps to buy a newer cd with them on or can you download to a USB with the cd 500?

You have to get new map updates on cd. Not sure if there is a cd on here being passed round

All the preface navi are pretty similar only difference is some has 3d mapping and bit more nav features.
