Sat Nav with no Post Code option

[Uday]

s600L 2000 w220


The nav system does not have an option for destination address by postcode.
What do I do? If i buy a new CD from Merc-Benz uk will it load up with this option as postcode is so handy now. Any other sugestions?
Please!

To enter the post code you have a row of numbers at the bottom of the screen where you put in the address,,just type in the first 2 letters of the post code, then a number and it will go from there, you will only get the first 4 to 5 in depending on the disc,, but it will then give you a list of roads within that post code
