Sat Nav disc upgrade

[goddo]

I have just bought a 2006 Continental GT and the sat nav disc fitted will only allow partial post code entries.
If I purchase, for example, a 2015 upgrade CD will I be able to enter the entire postcode?
Thanks for your help. I am sure I will be back with more questions later

Hi Flammetta, thanks for your reply.
You are correct. Since I posted this question, I have installed an upgrade CD and you cannot enter a full postcode on mine either.
Probably the worst aspect of the car all together in my opinion. The quality of map display is poor too.

Very quiet forum this one, isn't it?

This is a quiet forum compared to the Aston martin one that I have just migrated from.

Hi Speculatore,
I seem to be following you around, unintentionally of course.
I too, had an Aston Martin (DB9) before moving on to a Jaguar XFR and recently onto the Bentley.
As you say, the sat-nav is severely lacking in use-ability and display. Probably the poorest I've seen for a good few years.
