Sat Nav Problems!

[PrinceOfDarkness]

hi everyone!

i own a 2005 (55 plate) toyota avensis t-spirit which has the full screen sat nav that turns out of the dashboard. it's the same as the one show in this picture...

i am completely baffled by all the different tns model numbers and disc versions! i'm hoping that someone will be able to tell me exactly what model of sat nav i actually have because there is no writing on the unit and there's no hardware model number on the disc. in addition, i'm wanting to update the maps to a later version. can anyone tell me what disc i will need?

this is the picture of my current disc...

many thanks

Really easy, you need to goto

just put the numbers in that are on the disc and all will be revealed.

sorry, but that doesn't work. i've tried both numbers on the dvd and the site says they're not valid (or something along those lines)

i even called the dealer to ask them what system i have and they said they didn't know!
