Hi guys (and gals), the postcode option on my Satnav appears to have disappeared. It's a 61 plate TD4 and it had a software upgrade around 4 months ago. It was fine until about 5 or 6 weeks ago...

Any ideas?

 

Sounds like a UK reg? What satnav have you got? is it a Becker with a disc?

Some post codes in mine will only accept the first half and not the whole postcode. How did you achieve a software upgrade? or was it a new disc.
