I am thinking of buying a new E90 BMW 330i and was very impressed with the
front & back Park Control system with its graphics display! However to get
the graphics on this you need to buy the Sat Nav system as well (£1.5K in
the UK + PDC at £.5K)). This seems quite expensive for what I think is
probably a nice toy!

Can anyone suggest reasons as to why the Sat Nav is worth it? I don't travel
much on business in my own car (use a pool car) and generally know where I
am going (to my mothers and so on). Are there any potential advantages that
I have overlooked?
