Surely only you can answer this question. Do you have a need for nav, do you use it all the time or is it pretty much just a pretty picture on the dash board?

I never ticked the box as I have a need for nav maybe a few times a year at the most. The rest of the time i know where I'm going.

I know pro nav gives a lot more than just the nav element but to be honest those features are not worth £1600 when you already get the standard idrive for free anyway.
