Toyota B9010 Sat Nav

[simonjackson]

Hi all, i recently picked a toyota in dash satnav. i'll start with everything i have on it.

toyota B9010

Toyota 86662-00910

ref no CQ-XS6770AJ

serial 617257

type EA05A6

E13

I am getting a message on the screen saying ( program cannont be read, please consult to dealer)

i do have a maps disc with it and the part number is as follows (86271-53030) (A)

the unit is not responding to any fuctions keys, it will eject the disc but thats it.

i have tried disconnecting Battery, pulling the fuse etc, but nothing seems to make it work.

what i really need to know is, is it likley the unit or the disc is faulty?

i am also looking on the update wesite for maps, but they only state tns models, and i do not know which one i have?

if anyone could help, it would be great,i'm at the end of my teather and really need to sort it out

thanks to all
