Satellite Navigation - different types

[estoril]

Can anyone explain what the differences are between the business and professional satellite navigation systems?

Also, on my spec sheet I have many options, some are obvious but others I can't work out, what is, for example:

853 * Instrument Panel Letter
633 * Bluetooth phone prep and telemat (it's the telemat bit I don't understand...)
1CA * cop relative

 

[mmm-five]

Business Nav uses the small LCD panel of the radio for visual instructions. Prof Nav gives you the pop-up screen.

853 - is probably to do with language coding for the instrument display.
633 - 'Telemat' will be short for 'telematics' - or interactive telecommunications.
1CA - 'COP' stands for 'coil on plug' AFAIK - which means it doesn't have a single coil with a distributor but multiple coils controlled electronically.

Business Nav = Crap

Pro Nav = Less crap, and you get a handy screen for other things e.g. audio.

Joking aside, the Nav is alright (not worth the original price tag though - but 2nd hand is worth the premium) and I like the way it integrates with the car e.g. distances appear in the dials when you close in on a junction.
